Description
Technical Field
The utility model relates to a building room ventilation technical field, concretely relates to air handler system.
Background
In recent years, monomer buildings expand unprecedentedly, the building airtightness is continuously enhanced, in addition, the environmental pollution is gradually serious, the traditional natural ventilation mode can not meet the health and comfort requirements of human bodies on fresh air any more, in addition, if the humidity of the living environment is too high, insomnia and dreaminess can be caused, meanwhile, a large number of bacteria are easy to breed in the humid environment, in addition, furniture, clothes and the like can easily go moldy and have peculiar smell, and some fungi are easy to attach to dust, so that the possibility of diseases is caused.
But the air treatment equipment function on the market is comparatively single at present, and few equipment have the function that fresh air dehumidification regulation temperature air-purifying has concurrently, and it can bring inconvenience for the consumer to purchase multiple equipment, extravagant indoor space. Or the volume is great, contains the compressor and integrates in a box, and the noise is great, and the processing procedure is complicated, and the resident of being convenient for chooses by oneself. Therefore, new fans, dehumidifiers and other air treatment equipment with richer, more flexible and more convenient functions are receiving attention of consumers.
Application number CN201410058724.1, entitled "room temperature control ventilation system and its application", discloses a room temperature control ventilation system, which realizes the functions of energy saving, cooling, ventilation, air purification, etc. of a linkage air conditioner, but the device cannot realize the dehumidification function. Also, as in the patent document of application No. cn201611172058.x entitled "a room temperature control ventilation system", a room temperature control ventilation system is disclosed, which integrates the functions of fresh air heat exchange, internal circulation constant temperature dehumidification, dehumidification refrigeration, heating, air filtration and the like, but all rotating equipment including a compressor and the like are placed in a box body, an air duct is relatively tortuous, a plurality of processing units are arranged in the equipment, and the equipment has large volume, vibration and noise.
In order to solve the problems, the applicant develops a separated small-sized room temperature control ventilation system which has the functions of fresh air cooling and dehumidifying, constant temperature dehumidifying, heating, air filtering, optimization haze removing and the like, is small in size, light in weight, small in vibration and low in noise, and applies for patent CN 109959076A. The patent discloses a control method of an indoor fan with fresh air dehumidification and no cooling. The method is characterized in that two indoor heat exchangers are arranged in an indoor box body, one heat exchanger is controlled to become a condenser, the other heat exchanger becomes an evaporator, and fresh air firstly absorbs heat through the condenser and is heated, then is dehumidified and cooled through the evaporator and then is sent into a room. Thus, the evaporator and the condenser are positioned in a circulating system, so that the heat released and absorbed by the evaporator and the condenser during working should be the same theoretically, and the constant-temperature dehumidification effect can be achieved. Therefore, the defect that the temperature of fresh air is reduced due to the dehumidification mode of the conventional air conditioner fan is overcome.
The above patents still suffer from the following drawbacks: although two indoor heat exchangers are arranged in a circulating system, when fresh air passes through the two indoor heat exchangers, theoretically, heat absorbed by an evaporator is equal to heat released by a condenser, but actually, electric power equipment consumes electric energy and converts the electric energy into partial heat in the running process (specifically, a compressor in an air-conditioning circulating system can work to convert partial electric energy into internal energy and kinetic energy of a heat transfer medium, and the kinetic energy is converted into the internal energy finally, so that the heat of the air-conditioning system is increased, namely the actual heat release of the indoor condenser is larger than the heat absorption capacity of the evaporator, but moisture content in the air is removed after the fresh air is cooled and dehumidified by the evaporator, so that the heat required by wind flow after moisture removal to the original temperature is actually smaller than the heat taken away in the cooling process), and the released heat can be accumulated along with the increase of the running time of the equipment, therefore, the fresh air temperature can be gradually increased in actual operation, and the constant temperature dehumidification effect cannot be better achieved. In 2 above-mentioned patent, the new trend air inlet is afterwards earlier through the condenser intensification, then passes through the evaporimeter cooling dehumidification again, can lead to cooling dehumidification effect relatively poor like this, especially dehumidification effect relatively poor.

In order to solve the technical problem, the utility model discloses a following technical scheme:
an air handler system comprises an indoor box body installed indoors and an outdoor box body installed outdoors, wherein one end of an inner cavity of the indoor box body is provided with an air inlet interface for air inlet, the other end of the inner cavity of the indoor box body is provided with an air supply interface for air supply, a filtering structure is arranged in the position, close to the air inlet interface, of the inner cavity of the indoor box body, and an indoor heat exchanger is installed between the filtering structure and the air supply interface; an outdoor heat exchanger is installed in an inner cavity of the outdoor box body, a first heat exchange medium pipeline and a second heat exchange medium pipeline are connected and arranged on a heat exchange medium interface between the outdoor heat exchanger and the indoor heat exchanger, a compressor and a heat exchange medium flow direction switching device are installed on the first heat exchange medium pipeline, and an expansion valve is installed on the second heat exchange medium pipeline and forms a circulating heat exchange system with the first heat exchange medium pipeline;

Like this, set up two indoor heat exchangers in indoor box, can make an indoor heat exchanger become the evaporimeter through control, another indoor heat exchanger becomes the condenser for the new trend is sent into indoorly after two indoor heat exchangers realize twice heat exchanges in proper order. Meanwhile, the outdoor heat exchanger positioned outdoors can be controlled to be used as a condenser to release partial heat to the outdoors, so that the heat absorbed by the indoor heat exchanger used as an evaporator, the heat released by the indoor heat exchanger used as the condenser and the heat released by the air conditioning system in the indoor box body can be balanced, and constant-temperature dehumidification is realized. Therefore, the outdoor heat exchanger is additionally arranged to serve as a condenser, partial heat is released to the outdoor, and the heat absorption and the heat release in the indoor box body can be balanced. Therefore, constant-temperature dehumidification can be better realized, and the effect of dehumidification without temperature reduction is achieved.
Meanwhile, in the scheme, the bypass pipeline is connected in parallel between the access pipeline and the output pipeline of the outdoor heat exchanger, and the flow distribution condition of the heat exchange medium between the outdoor heat exchanger and the bypass pipeline is controlled through the flow control valve, so that the heat release control of the outdoor heat exchanger is realized. Therefore, the control process of the heat release of the outdoor heat exchanger cannot influence the overall circulation flow condition of the heat exchange medium in the heat exchange medium circulation pipeline, cannot cause the change of the flow quantity of the heat exchange medium in the other two heat exchangers, and cannot generate new variable factors. The overall control of the system can be more accurately realized. The specific control mode can obtain the corresponding relation between the control result and the control quantity under various working conditions through actual detection, and the corresponding relation is preset in the control device for control. For example, in the case of detecting different fresh air inlet temperature and air inlet amount by actual verification, to achieve the same outlet air temperature and inlet air temperature, the distribution amount of the heat exchange medium of the outdoor heat exchanger needs to be controlled to obtain a one-to-one correspondence relationship. And then the control can be realized in the control system according to the corresponding relation. Certainly, during implementation, the heat absorption amount or the heat release amount of the two indoor heat exchangers under different working conditions can be calculated according to an algorithm, and the calculated heat absorption amount or the heat release amount is converted into the heat exchange medium distribution amount required to control the outdoor heat exchanger to realize control, and the specific process is not described in detail here.
Furthermore, a first partition and a second partition are arranged in the inner cavity of the indoor box body along the ventilation direction and between the filtering structure and the air supply interface at intervals, a first air supply small chamber is formed between the first partition and the filtering structure, a second air supply small chamber is formed between the second partition and the first partition, a third air supply small chamber is formed between the second partition and the air supply interface, the first indoor heat exchanger is located in the second air supply chamber, the second indoor heat exchanger is located in the third air supply chamber, the first indoor heat exchanger is provided with an air inlet located on the first partition and an air outlet located in the second air supply chamber, the second indoor heat exchanger is provided with an air inlet located on the second partition and an air outlet located in the third air supply chamber, a first air valve capable of communicating the first air supply chamber and the second air supply chamber is further arranged on the first partition, and a second air valve capable of communicating the second air supply chamber and the third air supply chamber is further arranged on the second partition.
In this way, the valve air flow is better controlled to pass through the indoor heat exchanger in the working state in the indoor box body, and the valve air flow can be selected not to pass through the indoor heat exchanger in the non-working state. The heat exchange efficiency and the flow efficiency of the wind flow are improved.
Therefore, when the temperature control ventilation system of the building realizes constant temperature dehumidification control, the two air valves are closed firstly, so that fresh air in the indoor box body enters and then sequentially passes through the two indoor heat exchangers for heat exchange and then flows out. And then, by controlling the flow path of the heat exchange medium (closing the third electric control switch valve, opening the second electric control switch valve, opening the first electric control switch valve, and opening and adjusting the size of the electric control valve for the flow of the heat exchange medium), the heat exchange medium flows out of the first indoor heat exchanger through the first heat exchange medium pipeline, then passes through the compressor, then passes through the outdoor heat exchanger, then passes through the second heat exchange medium pipeline, and then sequentially passes through the second indoor heat exchanger and the expansion valve to return to the first indoor heat exchanger to form circulation. Therefore, the first indoor heat exchanger forms an evaporator, the outdoor heat exchanger and the second indoor heat exchanger form two condensers which are connected in series, and in the working process, the flow of the heat exchange medium flowing through the outdoor heat exchanger is controlled through the heat exchange medium flow electric control valve (the specific flow control size can be determined through theoretical calculation or preliminary experiments), so that the heat release of the outdoor heat exchanger is regulated and controlled, and the heat of the outdoor heat exchanger is matched with the heat increased by the operation of the air conditioning system in the indoor box body.

When the deep dehumidification and cooling is performed, the control mode is consistent with the conventional dehumidification and cooling, namely the first electronic control switch valve is closed, the heat exchange medium flow electronic control valve is completely opened, the third electronic control switch valve is opened, the second electronic control switch valve is closed to disconnect the second indoor heat exchanger, so that the heat exchange medium flows from the first indoor heat exchanger to the outdoor heat exchanger through the first heat exchange medium pipeline and the compressor, and then flows back to the first indoor heat exchanger through the second heat exchange medium pipeline and the expansion valve. In the control process, the frequency of the compressor is improved through adjustment to realize deep dehumidification and cooling. Meanwhile, the control of the reverse flow can realize the control of a conventional temperature rise mode and a deep temperature rise mode.
Furthermore, the periphery of the first indoor heat exchanger is also surrounded by heat pipes, and two ends of each heat pipe are respectively positioned at the front end and the rear end of the first indoor heat exchanger in the downwind flow direction.

Therefore, the heat exchanger and other components in the outdoor box body can be radiated by the exhaust fan.
Furthermore, the heat exchange medium flow direction switching device comprises a four-way control valve, two interfaces of the four-way control valve are connected to the first heat exchange medium pipeline, and the other two interfaces of the four-way control valve are respectively connected with the inlet and the outlet of the compressor through pipelines.
Therefore, the power direction of the compressor can be conveniently controlled to realize switching through the four-way control valve, and the four-way control valve has the advantages of simple structure, convenience in control, reliability, stability and the like.
Furthermore, the four-way control valve and the compressor are both arranged in the outdoor box body.
Therefore, the four-way control valve and the compressor can be well protected.
Further, the filtration includes the first filter stage and the first filter stage of imitating that the downwind flow direction set up, installs first filter module in the first filter stage of imitating, installs well filter module in the well filter stage of imitating, and well filter module filter effect is superior to first filter module of imitating.

Meanwhile, the outdoor heat exchanger positioned outdoors can be controlled to be used as a condenser to release partial heat to the outdoors, so that the heat absorbed by the indoor heat exchanger used as an evaporator, the heat released by the indoor heat exchanger used as the condenser and the heat released by the air conditioning system in the indoor box body can be balanced, and constant-temperature dehumidification is realized. Therefore, the outdoor heat exchanger is additionally arranged to serve as a condenser, partial heat is released to the outdoor, and the heat absorption and the heat release in the indoor box body can be balanced. Therefore, constant-temperature dehumidification can be better realized, and the effect of dehumidification without temperature reduction is achieved.
Meanwhile, in the scheme, the bypass pipeline is connected in parallel between the access pipeline and the output pipeline of the outdoor heat exchanger, and the flow distribution condition of the heat exchange medium between the outdoor heat exchanger and the bypass pipeline is controlled through the flow control valve, so that the heat release control of the outdoor heat exchanger is realized. Therefore, the control process of the heat release of the outdoor heat exchanger cannot influence the overall circulation flow condition of the heat exchange medium in the heat exchange medium circulation pipeline, cannot cause the change of the flow quantity of the heat exchange medium in the other two heat exchangers, and cannot generate new variable factors. The overall control of the system can be more accurately realized. The specific control mode can obtain the corresponding relation between the control result and the control quantity under various working conditions through actual detection, and the corresponding relation is preset in the control device for control. For example, in the case of detecting different fresh air inlet temperature and air inlet amount by actual verification, to achieve the same outlet air temperature and inlet air temperature, the distribution amount of the heat exchange medium of the outdoor heat exchanger needs to be controlled to obtain a one-to-one correspondence relationship. And then the control can be realized in the control system according to the corresponding relation.
