Specific embodiment
The present invention provides a kind of control method of shunt Wind-cooling type thermostatic and humidistatic air conditioning unit, for make the purpose of the present invention,
Technical solution and effect are clearer, clear, and the present invention is described in more detail as follows in conjunction with drawings and embodiments.Ying Ru
Fruit understands that described herein specific examples are only used to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, the present invention provides a kind of shunt Wind-cooling type thermostatic and humidistatic air conditioning unit, 90 in Fig. 1 are used to illustrate
Air circulation duct in the air conditioner, it is therefore intended that express the setting sequence of all parts in the channel.Arrow direction in Fig. 1
For the flow direction of circulation air.
The shunt Wind-cooling type thermostatic and humidistatic air conditioning unit includes shell (being not drawn into figure) and is set to the shell
Intracorporal compressor 101 is sequentially connected reheater condenser 102, expansion valve that the compressor 101 exports in the shell
105 and evaporator 106, it is set to the intracorporal humidifier 205 of the shell, the pressure fan being set at the air conditioner air outlet
206 and it is set to outdoor air-cooled condenser 102 and corresponding condensation fan 1021；The outlet of the evaporator 106 connects
The entrance of the compressor 101, the import of the reheater condenser 103 and the import of air-cooled condenser 102 pass through threeway ratio
Regulating valve 109 is connect with the outlet of the compressor 101, the outlet of the reheater condenser 103 and going out for air-cooled condenser 102
Mouth is connected in parallel the entrance of the expansion valve 105；The evaporator 106, reheater condenser 103 and humidifier 205 are along described
Air-flow direction is set gradually in shell.Above-mentioned threeway ratio adjusting valve is the form of " One In and Two Out ", threeway proportion adjustment
Two outlets of the outlet of valve import connect compressor, threeway ratio adjusting valve are separately connected air-cooled condenser and reheating condensation
Device.For the ease of illustrating, channel that the threeway ratio adjusting valve is connect with compressor is set as first passage, the threeway ratio
The interface channel of regulating valve and air-cooled condenser is second channel, the channel which connect with reheater condenser
For third channel.
The cyclic process of the working cycles of division refrigerant and air in detailed below:
Liquid refrigerant in the evaporator absorbs heat and the evaporation of air, is then sucked and is pressed by compressor
Contracting, compressed gaseous refrigerant is respectively enterd in air-cooled condenser and reheater condenser by threeway ratio adjusting valve to be condensed
Become low-temperature low-pressure refrigerant at liquid, then after throttling by expansion valve and enter evaporator, completes refrigerant circulating process.
Under the action of the pressure fan, air sucks to form circulation air from the return air inlet of air conditioner, circulation air warp
With liquid refrigerant heat exchange (refrigerant heat absorption at this time is evaporated) and by the elutriation in air out to realize drop when pervaporation device
Temperature, dehumidifying, circulation air is further across reheater condenser and the compressed gaseous refrigerant heat exchange (quilt of refrigerant heat release at this time
Condensation), i.e., the waste heat that script entrained by refrigerant should discharge into the atmosphere is used to heat cycles air, circulation air into
One step is by humidifier and humidifies to certain humidity, finally sends out from the air outlet of air conditioner, mixes with room air, mixes
Air afterwards is returned to the return air inlet of air conditioner, to form the working cycles of air.
Heat needed for being greater than circulation air heating due to the waste heat generated in refrigerant working cycle process, institute
The reheater condenser stated can replace the high-power electric heater in the thermostatic and humidistatic air conditioning unit of the prior art completely, not only realize
Heating to circulation air, while having saved mass energy, so that and when avoiding high-power electric heater and running
Overheat, overcurrent, the problems such as burning or even is on fire, improve the security reliability of air conditioner.In addition, the present invention passes through threeway ratio
Example regulating valve is distributed to adjust into the refrigerant of reheater condenser and air-cooled condenser, that is, is realized step-less adjustment and entered reheating
The refrigerant flow (i.e. step-less adjustment enter reheater condenser waste heat heat) of condenser, thus can according to actual needs,
The refrigerant of most suitable flow is provided to reheater condenser, the control precision of the air conditioner greatly improved.It can be seen that this hair
It is bright by the way that reheater condenser is arranged, be effectively utilized and need to be dispersed into waste heat in atmosphere originally, saved a large amount of energy, together
When, by and air-cooled condenser by threeway ratio adjusting valve carry out refrigerant shunt regulating, improve control precision, protect
It is reliable and stable, energy-efficient the operation of air-conditioner has been demonstrate,proved.
Due in practical application, it is less in the case where the compressor 101 of air-conditioning do not need to open, it is empty in order to still reach
The constant temperature effect of gas is additionally provided with electrical auxiliary heater 20 between the reheater condenser 103 and humidifier 205, i.e., if
When compressor 101 does not start, the circulation air in the air conditioner is heated by electrical auxiliary heater 204, is met
The air conditioner operates normally.It should be noted that above-mentioned electrical auxiliary heater is to open to carry out auxiliary heating under a few cases,
Therefore the high-power electric heater of thermostatic and humidistatic air conditioning unit compared with prior art, power is small, runing time is few, does not burn
The security risks such as ruin, be on fire.
Further, in the shunt Wind-cooling type thermostatic and humidistatic air conditioning unit, the entrance of the expansion valve is connected with one
Liquid storage device, the entrance of the liquid storage device connect the outlet of the reheater condenser and the outlet of air-cooled condenser.Through air-cooled condensation
Device and the liquid refrigerant of reheater condenser condensation enter fluid reservoir and are buffered, and are then gone forward side by side by expansion valve flow restriction control
One stepping enters evaporator, i.e., so that into the liquid refrigerant of evaporator the available control of flow, ensure that air passes through
Can effectively it be cooled down when evaporator, dehumidify purpose.
In order to improve the purified treatment to air, air filter 201 is additionally provided at the return air inlet of the air conditioner.
I.e. air first passes through the air filter 201 and carries out purified treatment, and subsequently into air conditioner inside, therefore the air conditioner is full
On the basis of sufficient room air constant temperature and humidity, the degree of purification of air is further improved.
