Description
Technical field
A kind of air conditioner dehumidifier combined unit is the utility model is related to, the function of existing cooling and heating air conditioner, there is dehumidifying again
Machine function, belong to indoor air temperature, the control and regulation field of humidity.
Background technology
Air conditioner and dehumidifier are regulation temperature, the common equipment of humidity in building respectively.Air conditioner and dehumidifier are equal
For heat pump, it is also identical using part and operation logic.But existing air conditioner and dehumidifier are often all only paid attention to respectively
From independent application, fail completely to be combined into one its function；Air conditioner can not be used in some temperature humidity ranges in other words
Dehumidifier is made, after user buys air conditioner, it is also necessary to buy dehumidifier in addition.And existing Domestic dehumidifying acc power and moisture removal
Small, noise is big, summer operation when raise indoor temperature, it is impossible to meet the needs of indoor dehumidification, while cause device resource again
And the interior space waste.
The existing mode for reducing indoor air relative humidity：
First, air conditioner refrigerating dehumidifies
Air conditioner can realize dehumidification function when temperature is higher indoors by running refrigeration mode.Air conditioner operation refrigeration
When, the water vapor condensation in the air flowed through is that aqueous water discharge is outdoor by indoor evaporator, so as to which the humidity of interior be reduced.
Its principle be reduce air in moisture so that absolute humidity and relative humidity in air all reduce.
But when indoor temperature is below 20 DEG C, it is by the water vapor condensation in room air such as by way of refrigeration
Aqueous water discharge is outdoor, will necessarily constantly reduce the temperature of room air.And during less than 20 DEG C room temperatures refrigeration indoor set air-out
For temperature below 12 DEG C, adverse effect will be brought to health and comfortableness by blowing on the person；The descent tape of temperature is come simultaneously
The raising of relative humidity, the effect of meeting partial offset dehumidifying.And indoor temperature be less than 16 degree when, conventional air conditioner refrigeration mould
Formula is just stopped, and dehumidifying cannot continue.Although existing air conditioner is also equipped with dehumidification function, either refrigeration mode
Dehumidification function under lower or dehumidification mode, used when being typically suitable only for indoor temperature higher than 20 DEG C, many times in 1 year
Be not suitable for using.
2nd, air-conditioning heating reduces relative humidity
If water loading of the air is constant, temperature improves, and the relative humidity of air will decline.Its rule is about temperature
Degree often raises 2 DEG C, and relative humidity is the 90% of former relative humidity.Temperature such as air is 20 DEG C, and relative humidity is 70%, then when
Temperature rises to 22 DEG C, then relative humidity, which reduces, is changed into about 63%.
Air conditioner heating when, can by indoor air temperature improve so as to reduce relative humidity, its reason be high temperature sky
Gas has a bigger moisture carrying capacity, rather than the moisture in air is removed, reduction be relative humidity rather than it is definitely wet
Degree, water loading of the air are not reduced.But decline sometimes with the raising of indoor air temperature and relative humidity, it is indoor various
The moisture included in article can discharge, and relative humidity is accordingly increased.If interior has moisture to be constantly discharged into sky
In gas, the vapor as caused by the indoor daily lifes such as the breathing, culinary art, bathing of people is relatively wet even if indoor temperature is higher
Degree can still exceed zone of reasonableness, therefore the method for adjusting indoor relative humidity by air-conditioning heating has its limitation.Maintain simultaneously
Indoor air temperature is higher than outdoor temperature, it is necessary to air conditioner continuously works, and consumes substantial amounts of energy.Therefore, by air conditioner not
It is also that infeasible, actual service condition also illustrate that this that disconnected heating, which reduces the method for indoor relative humidity many when,
Point, the high area of humidity such as seashore building are being provided with the occasion of air conditioner, when needing dehumidifying in winter, are still needing to install
Dehumidifier.
3rd, dehumidifier dehumidifier
The principle of dehumidifier is identical with air conditioner, and evaporator absorbs the air cooling-down that heat makes to flow through, and air themperature is less than
During dew-point temperature, the moisture in air, which can be condensed into aqueous water and be removed from air, declines the absolute humidity of air.Dehumidifier
Condenser and evaporator be all placed on interior, pass through condensation because heat can be discharged when moisture in air is condensed into aqueous water during dehumidifying
Device is discharged into air, plus the power consumption of dehumidifier in itself, during operation, indoor air temperature will be made to have increased；So as to
The relative humidity of room air is reduced in terms of the temperature two of the moisture in room air and raising room air is reduced.
The existing general power of domestic dehumidifying machine is below 650W, and majority is 300W or so.And 300W dehumidifier one is small
When water removal below 0.3 kilogram, water storage case capacity is less than 4 liters, general water storage case be with 12 hours fall a water set
Meter, only about 5-6 kilograms daily of actual dehumidifying effect.
Vapor caused by life is about as follows daily for the family of four in a set of 100 square metres or so houses:Culinary art 3 is public
Jin, do washing 1 kilogram, everyone 1.5 kilogram of * 4 people=6 kilogram of having a bath, gas-fired produces 2 kilograms of aqueous vapor, human body respiration and distributes
0.1 kg/hour of * 12*4 people=4.8 kilogram, window, crack between a door and its frame tide vapour penetrate into 20 kilograms of interior, are aggregated in more than 35 kilograms.Such as
In rainy day, humid area and season, the numeral can also improve.
It can be seen that in many humid regions and season, the family of four in a set of 100 square metres or so houses, one per small
When 0.3 kilogram of moisture removal dehumidifier can not be effectively reduced interior relative humidity, actual dehumidifying far can not be met
Demand.If increasing the power of dehumidifier, the noise of dehumidifier also increases therewith, and dehumidifier must necessarily be placed in interior, high-power
The noise of 650W dehumidifiers is to endure the limit.When temperature is higher than 25 DEG C indoors simultaneously, the operation of dehumidifier, indoor temperature will be made
Rise, 1 kilogram of vapor is often condensed, the heat of about 570 kilocalories is discharged, need air conditioner refrigeration that heat is discharged into room again
Outside.
Summarize：A kind of equipment is currently there are no reasonable, thorough, synchronous to solve in humid area and wet season room
Temperature and dehumidifying problem.Really to solve the problems, such as family's indoor dehumidification, the equipment must is fulfilled for following four condition：Remove per hour
2 to 4 liters of moisture, plant capacity is in more than 1KW；Room noise is below 45 decibels；Adapt to various indoor and environment temperature
Use:Including cooling in summer dehumidifying, spring and autumn constant temperature dehumidification, winter heating dehumidifying；Easy for installation, installation difficulty is not above existing
There is the installation of separating air conditioner.
For above-mentioned problem and demand, the stakeholder in some dehumidifiers and air conditioner industry, which also has, certain to be recognized
Know, and propose some solutions, disclose the patent of correlation.But since it is desired that consider various links it is more, difficulty compared with
Height, involves the factors such as cost, technique, the reliability of critical component, and in the market does not occur the air conditioner dehumidification joint of maturation
Device.
Some have used more complicated structure and multiple magnetic valves in disclosed air conditioner dehumidification combined unit patent.Compared with
Complicated structure causes the increase of cost and volume, also causes the reliability decrease of equipment；In the heat pump of similar air-conditioning,
Because the pressure of refrigerant is very high, the sealing of bidirectional electromagnetic valve is deteriorated, and causes secondary refrigerant leakage；In the market has the unidirectional cutoff of maturation
Valve, but lack the two-way shut-off valve available for high pressure refrigerant.If using refrigerant two-way shut-off valve reluctantly, secondary refrigerant leakage can be caused
With stop valve caused by failure, cause scheme possible in theory, actual product can not stablize use, experiment it is verified this
Point.
Utility model content
For the deficiency of existing air conditioner and dehumidifier, it is proposed that a kind of air conditioner dehumidifier joint dress of the present utility model
Put, air conditioner is possessed dehumidifier completely, simple in construction, cost is low, has diversified function.
Therefore, the utility model takes following technical scheme：A kind of air conditioner dehumidifier combined unit, including one complete

The position A described in pipeline S is in position B downstream；The relevant position of each part is A → Dehumidification controlling valve on loop dehumidification
(7) → dehumidify evaporimeter (6) → dehumidifying stop valve (8) → B；(Fig. 1,2) it is described dehumidifying stop valve (8) all the time prevent refrigerant except
A is flowed to from B in wet loop, and allows refrigerant to flow to B from A in loop dehumidification under certain conditions；The Dehumidification controlling valve (7)
The flowing of refrigerant in loop dehumidification can be controlled.Flow through indoor heat exchanger (4) air quantity be more than flow through dehumidify evaporimeter (6) air quantity
1.2 times.Dehumidifying stop valve (8) and Dehumidification controlling valve (7) are turned off when the combined unit is as operation of air-conditioner；It is described
Attach together and put when being dehumidified as dehumidifier, there is valve member (2) (Fig. 1) or valve member (9) (Fig. 2) to make pipe between pipeline S position A and B
Road S is separated, and the indoor heat exchanger (4) is used as condenser, and dehumidifying stop valve (8) is opened, Dehumidification controlling valve (7) is not closed,
Magnetic valve (10) is opened, and outdoor heat exchanger does not work, to indoor air dehumidification；The combined unit runs as dehumidifier and heated up
Dehumidification mode, when carrying out heating dehumidifying simultaneously to room air, indoor heat exchanger (4) is condenser, the stop valve (8) that dehumidifies is beaten
Open, Dehumidification controlling valve (7) is not closed, magnetic valve (10) is closed, and has refrigerant in dehumidify evaporimeter (6) and outdoor heat exchanger (3)
Gaseous state is evaporated to from liquid.This patent scenario-frame is simple, practical, and the loop dehumidification design of indoor set is unique ingenious, increases

Ensure the indoor heat exchanger as condenser again has larger air quantity leaving air temp is not increased above 45 DEG C, makes refrigerant cold
Solidifying temperature is maintained at rational scope, and the system of ensure that has higher COP；Dehumidification mode in conventional air-conditioning machine is exactly by room
The air quantity of interior evaporator is turned down, and its principle is identical.This feature it also avoid on existing conventional dehumidifier evaporate air quantity with
It is equal to condense air quantity, when air themperature is higher such as more than 25 DEG C, because refrigerant condensation temperature is too high when relative humidity is more than 80%
The drawbacks of causing system COP relatively low.Especially described device is when running so-called heating dehumidification mode, because only that part is cold
Matchmaker is evaporated in dehumidify evaporimeter, and refrigerating capacity is smaller, if the air quantity for flowing through dehumidify evaporimeter is equal with condensation air quantity, can make stream
The air themperature for crossing dehumidify evaporimeter is dropped under less than dew-point temperature, it is impossible to dehumidifies, or the leaving air temp of condenser is higher than 45 DEG C,
COP significantly declines.
