The present invention proposes an air-injection enthalpy-increasing air-conditioning system, which includes an air-conditioning indoor unit, at least two parallel-connected air-conditioning outdoor units, a main refrigerant pipeline, a main refrigerant pipeline loop, an air injection device and an enthalpy-increasing pipeline, and each air-conditioning outdoor unit includes Air injection enthalpy increasing compressor, outdoor unit heating components, enthalpy increasing branch connected to air injecting enthalpy increasing compressor and surrounding outdoor unit heating components; one end of the enthalpy increasing pipeline is connected to the air injection device, and the other end is connected to each air conditioner outdoor unit; The air injection device is installed at any node of the main refrigerant pipeline. The refrigerant entering the enthalpy-increasing pipeline absorbs the heat of the air injection device and the heating components of the outdoor unit, evaporates into a medium-pressure gaseous refrigerant, and flows into the air-injection enthalpy-increasing compressor of each air-conditioning outdoor unit. . The invention reduces the temperature of the heating components of the outdoor unit while realizing the increase of enthalpy by air injection, and does not need to add expansion valves and corresponding pipelines. The air injection device can be installed flexibly, greatly reduces the cost of the system, and avoids waste of resources.
Description
technical field [0001] The invention relates to the field of vapor compression refrigeration and air conditioning, in particular to an air-jet enthalpy-increasing air-conditioning system. Background technique [0002] As the power of the inverter air conditioner increases, the calorific value of its electronic heating elements also increases. If the heat is not dissipated in time, its performance will be reduced or even burned. The existing method is to use the refrigerant to absorb the heat generated by the electronic heating element to increase the enthalpy by injecting air, which not only reduces the temperature of the electronic heating element, but also improves the enthalpy value and energy efficiency ratio of the air conditioning system. However, when multiple outdoor units are connected in parallel, it is necessary to Setting multiple expansion valves and corresponding pipelines independently increases the cost. Contents of the invention [0003] The main purpose ...
