Air-refrigerant heat exchanger has mutually independent coolant channel and air duct, can select finned tube exchanger or micro-
Channel heat exchanger.
A kind of disclosed single complete straight swollen warm and humid sub-control air-conditioning system of type of refrigerant circuit, has intelligence and system
Hot two kinds of operating modes, specific workflow are as follows：
Refrigeration cycle
As shown in Fig. 2, cooling down to the fresh air of feeding by the air-conditioning system in summer, it is carried out at the same time the multi-joint place of return air sensible heat
Reason, the first port of the first four-way reversing valve and the second four-way reversing valve be connected to second port under the pattern, third port with
4th port is connected to, and outdoor heat exchanger is as condenser, and the multi-joint heat exchanger of sensible heat is as evaporator, and fresh air heat exchanger is also as steaming
Send out device.
Specifically refrigerant circulating process is：Double suction atmospheric pressure compressor discharging refrigerant is sent into the first four-way reversing valve and the
The first port of two four-way reversing valves, and be discharged from second port and two-way is divided by pipeline, wherein freezing machine is admitted to all the way
Outdoor heat exchanger cooling condensation, another way are sent directly into reheating heat exchanger 4 by pipeline, add to the fresh air after cool-down dehumidification
Heat reaches comfortable temperature value, and condensing agent enters pipeline by pipeline by the first expansion valve and check valve later, and outdoor is changed
The refrigerant that hot device comes out is sent into indoor unit, after being mixed with the refrigerant of heat exchanger again all the way by being again divided into two-way
It is sent into fresh air heat exchanger, cool-down dehumidification is carried out to fresh air, refrigerant after heating is sent via pipeline to the of the first solenoid valve
Three ports, and pass through the air entry that the first solenoid valve is sent into double suction atmospheric pressure compressor by pipeline in the 4th port, and it is outdoor
The another way that heat exchanger comes out is laggard through the multi-joint expansion valve throttling expansion of sensible heat then by the multi-joint end of each sensible heat of piping connection
Enter the multi-joint heat exchanger of sensible heat, the indoor return air sent to the multi-joint wind turbine of sensible heat cools down, and refrigerant again by the road, is sent after heat absorption evaporation
Enter the second four-way reversing valve, and returns to the air entry of double suction atmospheric pressure compressor by second solenoid valve.
When closing the first solenoid valve, unit only freezes return air, does not handle fresh air；When closing second solenoid valve, unit
Fresh air is only handled, return air is not handled；When the first solenoid valve and second solenoid valve unicom simultaneously, bridge joint solenoid valve remains turned-off；
When the first solenoid valve or second solenoid valve are closed, solenoid valve can be bridged with unicom and increase refrigerating capacity, the first expansion valve can be adjusted
Save the new air temperature after reheating.
The processing procedure of air is that fresh air first passes through air filter in air supply duct, removes the dust in air, then
Dew-point temperature or more is warming up to by cool-down dehumidification, then heat exchanger by fresh air heat exchanger, is most sent into room through fresh-air fan afterwards.
Heating cycle
As shown in figure 3, heating up in winter to the fresh air of feeding by the new wind turbine, it is carried out at the same time the multi-joint place of return air sensible heat
Reason, the first port of the first four-way reversing valve and the second four-way reversing valve be connected to the 4th port under the pattern, second port with
Third port is connected to, and outdoor heat exchanger is also used as cold as evaporator, the multi-joint heat exchanger of sensible heat as condenser, fresh air heat exchanger
Condenser.
Specifically refrigerant circulating process is：The refrigerant of double suction atmospheric pressure compressor discharge is divided into two-way, all the way through the
One four-way reversing valve enters fresh air heat exchanger heating fresh air, and another way enters each sensible heat through the second four-way reversing valve, by pipeline
The multi-joint heat exchanger of sensible heat of multi-joint end, is heat-treated return air again, after two-way refrigerant converges, throttles through third expansion valve
Cooling is absorbed heat into outdoor heat exchanger from air, and finally, the refrigerant after gasification heating is through the first four-way reversing valve and the two or four
Logical reversal valve, returns to two air entries of double suction atmospheric pressure compressor respectively, completes heat pump cycle.
Under heating condition, the first solenoid valve and second solenoid valve keep unicom, bridge joint solenoid valve to remain turned-off；When closing the
When two expansion valves, unit only handles return air, does not handle fresh air；When the multi-joint expansion valve of closing sensible heat, unit only handles fresh air, no
Handle return air.
The processing procedure of air is that fresh air first passes through air filter in air supply duct, removes the dust in air, then
It is warmed by fresh air heat exchanger, then humidified device humidification, is most sent into room through fresh-air fan afterwards.
Not complete all components of displaying refrigerant circulation and air duct in above-described embodiment, in implementation process, are selected different
It is auxiliary that the common refrigeration such as high-pressure reservoir, gas-liquid separator, oily separation, filter, drier are arranged in refrigerant circuit in refrigerant
Silencer, auxiliary heater is arranged in air duct in part, and the air-treatments attachment such as sterilizing unit changes wind turbine position, increases or decreases
The quantity of the multi-joint end of sensible heat cannot be considered as and carry out substantial improvements to the present invention, should belong to the scope of the present invention.
The words such as " first " used herein, " second " limit component, and those skilled in the art should know：" the
One ", the use of the words such as " second " is intended merely to facilitate in description and is distinguished to component.Such as without Stated otherwise outside, on
Predicate language has no special meaning.
Finally it should be noted that：Above-described embodiment is presently preferred embodiments of the present invention, is not to the technology of the present invention
