The invention provides an air-cooling evaporation cold low-temperature type multi-connected unit. The air-cooling evaporation cold low-temperature type multi-connected unit comprises a low-temperaturejet enthalpy-increasing compressor with two refrigerating medium reflux ports and a first heat exchange part; the first heat exchange part includes an air-cooling heat exchanger, a fan making air flow through the surface of the air-cooling heat exchanger, an evaporation cold heat exchanger and a spraying assembly for spraying cooling water onto the surface of the evaporation cold heat exchanger.The air-cooling evaporation cold low-temperature type multi-connected unit, whether in a heating mode or a refrigerating mode, can stay in a cooperative working state in which the air-cooling heat exchanger and the evaporation cold heat exchanger work cooperatively; compared with existing multi-connected units, the multi-connected unit has the advantages of a larger evaporation area and a larger condensing area, and thus the heating efficiency and the refrigerating efficiency are higher; moreover, the two refrigerating medium reflux ports are simultaneously started in the heating mode so thatheating can be performed efficiently in an outdoor environment at the temperature as low as -25 DEG C, thus original technical bottlenecks are broken through, and the use range of the unit is expanded.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to an air-cooled evaporative cooling and low-temperature multi-connection unit. Background technique [0002] At present, there are three main cooling methods for air conditioning units: [0003] Air-cooled mode, using air to exchange heat with the cooling medium; [0004] The water-cooling method uses cooling water and refrigeration medium, and both the cooling water and the refrigeration medium flow inside the condenser. [0005] The evaporative cooling method also uses the cooling water to exchange heat with the cooling medium. Unlike the water cooling method, the evaporative cooling method sprays the cooling water directly on the surface of the condenser, and uses the latent heat of vaporization of water to remove heat. [0006] The multi-connected unit can be classified into the air-cooled category in terms of cooling methods. The difference from the air-cooled chiller is ...
