The utility model is characterized in that the air handling device is provided with a direct evaporative system electrically connected with the electrical control system; and the direct evaporative system is formed by an indoor direct evaporative coil and an air-cooled heat pump outdoor unit which is arranged outside and is connected with the indoor direct evaporative coil through a pipeline. The utility model has the advantages of the concentrated cooling (or heating) of the central air conditioner and advantages of the directly-cooled evaporative unit. The cold water coil and the direct evaporative coil can realize the flexible switching and mutual compensation through an electrical control line. Thereby, the utility model has the advantages that the energy-saving effect is obvious during the operation in transitional seasons and the service life of the system is prolonged.
Description
Technical field
The utility model relates to a kind of air regulator, especially relates to a kind of a kind of air-conditioning system with two Cooling and Heat Source.
Background technology
Water carries out central cooling as carrier or heating is present the most frequently used a kind of air-conditioning system, and some local air-conditioned room still needs refrigeration at transition seasons such as spring, autumns because of heat radiations such as indoor equipment, illumination, personnel in this air-conditioning system; As some the hospital operating room of specific (special) requirements is arranged, still need use central air-conditioning cooling (or heating) at night or transition season; May also have some air-conditioned rooms because of being in the building periphery, be subjected to outdoor environment to influence big and may need cooling (or heating).These partial cold-supplies (or heating) can cause that 1. the design refrigeration duty of chilling requirement and whole air-conditioning system does not match, and cause handpiece Water Chilling Units to open frequently, fragile unit part and shorten its life-span; When underrun, according to the handpiece Water Chilling Units characteristic curve as can be known, its refrigerating efficiency is extremely low to handpiece Water Chilling Units for a long time, therefore causes energy waste.2. the contradiction between cooling and the heating demand can't well be coordinated.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency; thereby when developing a kind of air-conditioning system that is used for central cooling (or heating) and shutting down; when local air-conditioned room still need freeze or heat, can meet the demands and energy savings, prolong system's two Cooling and Heat Source air processors in service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of pair of Cooling and Heat Source air processor, have wind-mixer, filter, the chilled water coil that is communicated with central air conditioner system, heater, blower fan, sterilization filter, directly vaporation-type coil pipe and electric control system thereof, it is characterized in that: described air processor is provided with the direct vaporation-type system that is electrically connected with electric control system; Described direct vaporation-type system by indoor direct vaporation-type coil pipe be arranged at the outdoor unit of air-cooled heat pump outdoor, that be connected by pipeline with indoor direct vaporation-type coil pipe.
The design mainly is at night or transition season partial air conditioning room still needing the concentrated central air conditioner system of cooling (or heating) to develop.As at conventional medical sanitary lustration type constant temperature and humidity machine, on the basis of an original chilled water coil 1 and heater 3, increase a direct vaporation-type coil pipe 2 again, change the air processor of original routine into two cold (heat) sources air processor.Constitute two cold (heat) source air-conditioning systems.When central air conditioning cooling (or heating), clean rooms etc. are lowered the temperature by chilled water coil pipe or heater or heats (control is provided with water cooling or heating preferentially); When central air-conditioning such as night or transition season stopped to supply water, the room was as still needing cooling or heating, and unit can start the supporting compressor of direct-cooled coil pipe automatically, and space air is lowered the temperature or heated.Direct-cooled system mainly is made up of indoor direct vaporation-type coil pipe 2 and Air-Cooled Heat Pump Unit 7 (off-premises station) two parts, with the cold-producing medium copper pipe evaporation coil of indoor units and the outdoor unit of air-cooled heat pump is coupled together to get final product.Evaporation coil and the supporting use of original air-conditioning, other functions of room air processor all can be shared.Because of direct vaporation-type coil pipe in pair cold (heat) air conditioning chambers, source links to each other with off-premises station, the air-conditioning of any system is opened, and the corresponding unlatching automatically of off-premises station need not to start handpiece Water Chilling Units and water pump in advance, thereby has improved the flexibility of air-conditioning equipment use greatly.
Therefore; the utility model has the advantage of central air-conditioning central cooling (or heating) system and direct-cooled vaporation-type system concurrently; chilled water coil (or heater) is passed through electric control circuit with direct vaporation-type coil pipe; realize switching flexibly and can replenishing mutually; therefore operation of air-conditioner is more flexible; under any environmental condition, all can start; and can effectively avoid causing that because of concentrating central air-conditioning to shut down air-conditioning lost efficacy; guarantee that air-conditioned room humiture precision is controlled in the designing requirement scope; in transition season operation remarkable energy saving effect is arranged, and can prolong system service life.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Two cold (heat) source air processor as shown in Figure 1 has wind-mixer 6, filter, the chilled water coil 1 that is communicated with central air conditioner system, heater 3, blower fan 4, sterilization filter 5; Direct vaporation-type coil pipe 2 is housed between chilled water coil 1 and heater 3, and the outdoor unit 7 of air-cooled heat pump that is connected with direct vaporation-type coil pipe is arranged at outdoor, and the two connects by pipeline.
Central air-conditioning chilled water (hot water) centralizedly supply means that all air-conditioned rooms can only cooling or heat supply, and two cold source system can be adjusted operational mode automatically according to the humiture of different air-conditioning system needs, and arbitrary system all can freeze or heat.Boiler or handpiece Water Chilling Units, freezing cooling water pump, cooling tower must move during the central air-conditioning operation, this part power consumption accounts for the 60%-70% of the total power consumption of whole building, use central air-conditioning because of local environment needs cooling (or heating) as in the night or during outdoor environment temperature higher (or lower) such as transition season, can cause the waste of the energy.If local room need reach design temperature fast, also can directly evaporate unit and central cooling (heating) equipment and move rapidly simultaneously and achieve the goal.
In addition as in the cryosurgery chamber of medical domain (the operation temperature requirement that refers to special requirement here is 16 ℃ ~ 18 ℃ a operating room), need sometimes indoor temperature is reduced to 18 ℃ rapidly from normal 24 ℃, or even 16 ℃.After a period of time, need be returned to normal temperature rapidly from low-temperature condition, this just needs direct vaporation-type unit to be used with central air conditioner system, learns from other's strong points to offset one's weaknesses, and brings out the best in each other.Directly the vaporation-type unit stands ready, and as insufficient water when deficiency or central air-conditioning fault (when the room needs low temperature deficiency), direct-cooled vaporation-type unit starts operation at once, reaches the humiture requirement of setting, has guaranteed needs annual, round-the-clock use.
