Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Air conditioner 100 according to an embodiment of the present invention is described below with reference to Fig. 1-Fig. 4, which can be to interior
Air is freezed and/or is heated.
As Figure 1-Figure 4, air conditioner 100 according to an embodiment of the present invention, including refrigerant circulation flow path, intermediate heat exchange mould
Block 5 and the first control valve group 8a.
Compressor 1, outdoor heat exchanger 2, indoor heat exchanger 3 and restricting element 4 can be equipped on refrigerant circulation flow path, it is outdoor
Heat exchanger 2 and indoor heat exchanger 3 can be connected with compressor 1 respectively, and restricting element 4 can be connected on outdoor heat exchanger 2 and room
Between interior heat exchanger 3, one of them in indoor heat exchanger 3 and outdoor heat exchanger 2 can be condenser, 3 He of indoor heat exchanger
Another in outdoor heat exchanger 2 can be evaporator.
Specifically, refrigerant can be logical in refrigerant circulation flow path inner recirculation flow when air conditioner 100 is run.Wherein, work as sky
When device 100 being adjusted to carry out refrigeration work, outdoor heat exchanger 2 may be used as condenser, and indoor heat exchanger 3 may be used as evaporator.Pressure
The gaseous coolant for the high temperature and pressure that compression is completed in contracting machine 1 can enter in outdoor heat exchanger 2, and the refrigerant of high temperature and pressure is in room
It exchanges heat in external heat exchanger 2 with outdoor air, refrigerant is converted to the state of medium temperature and medium pressure.Restricting element 4 can be to from room
The refrigerant of the medium temperature and medium pressure of external heat exchanger 2 carries out reducing pressure by regulating flow, and refrigerant is converted to the state of low-temp low-pressure.The liquid of low-temp low-pressure
Refrigerant is flowed into indoor heat exchanger 3 and exchanges heat with room air, and liquid refrigerants evaporation endothermic is simultaneously converted to gaseous state, thus may be used
To play the purpose for reducing room temperature, finally in gaseous refrigerant return to compressor 1, a refrigeration cycle is thus completed.
When air conditioner 100 carries out heating work, outdoor heat exchanger 2 may be used as evaporator, and indoor heat exchanger 3 can be used
Make condenser.The gaseous coolant for the high temperature and pressure that compression is completed in compressor 1 can enter in indoor heat exchanger 3, and high temperature is high
The refrigerant of pressure exchanges heat in heat exchanger 3 indoors with room air, it is possible thereby to play the purpose of promotion room temperature, refrigerant
It is converted to the state of medium temperature and medium pressure.Restricting element 4 can the refrigerant to the medium temperature and medium pressure from indoor heat exchanger 3 carry out throttling drop
Pressure, refrigerant are converted to the state of low-temp low-pressure.The liquid refrigerants of low-temp low-pressure flow into outdoor heat exchanger 2 and and outdoor air into
Row heat exchange, liquid refrigerants evaporation endothermic are simultaneously converted to gaseous state, in last gaseous refrigerant return to compressor 1, thus complete one
A heating circulation.

Dividing can enter directly into condenser.Refrigerant can be with the heat exchange in intermediate heat exchange module 5 when circulating in intermediate flow passage 52
Part 51 exchanges heat, refrigerant by high temperature and pressure condition conversion at medium temperature and medium pressure state, complete heat exchange refrigerant pass through centre
The outlet end of flow path 52 is flowed out and is flowed into condenser, it is possible thereby to the temperature in condenser is reduced, it is cold so as to reduce
Condensing pressure in condenser can be prevented because condensing pressure is excessively high to cause compressor 1 to be frequent stoppage protection the case where, can
To ensure the normal operation of air conditioner 100.When the condensing pressure in condenser meets normal operation demand, can choose
One control valve group 8a is closed.
It is understood that when outdoor temperature is higher while air conditioner 100 is freezed or heats work, or
When the very low air conditioner 100 of outdoor temperature is there is still a need for heating work is carried out, refrigerant is converted in the case where temperature is certain by gaseous state
Pressure when liquid becomes larger, i.e., condensing pressure increases, and causes the inlet pressure of condenser increased dramatically, compressor 1, which will appear, to stop
The phenomenon that machine is protected, air conditioner 100 is out of service, to not be able to satisfy the use demand of user.Pass through the intermediate mould that exchanges heat of setting
Block 5, intermediate heat exchange module 5 can exchange heat to the refrigerant in intermediate flow passage 52, and the refrigerant for the completion that exchanges heat can enter cold
In condenser, it is possible thereby to the temperature and condensing pressure that are effectively reduced in condenser, so as to ensure the normal fortune of air conditioner 100
Row.
