Problems solved by technology

All kinds of dust and dust contained in the outdoor air are easy to adhere to the surface of the finned surface heat exchanger, thereby increasing the heat transfer resistance of the finned surface heat exchanger, resulting in the failure of the finned surface heat exchanger. Decreased heat exchange efficiency leads to lower unit energy efficiency and increased power consumption

Embodiment 1

[0024] Embodiment 1: during refrigeration:

[0025] The high-temperature and high-pressure gaseous refrigerant passes through the refrigerant circulation pipeline 3 and flows into the finned surface heat exchanger 1 to condense through the refrigerant pipeline inlet 11, and then flows into the water-refrigerant heat exchanger 5 through the refrigerant circulation pipeline 3 to be cooled into a completely liquid refrigerant, and then passes through the refrigerant pipeline Outlet 12 flows out.

[0026] Powered by the circulating water pump 6, the low-temperature water is first sent to the water-refrigerant heat exchanger 5 to exchange heat with the refrigerant through the circulating water pipeline 7, and the water that absorbs the heat of the refrigerant is then sent to the water distributor 8 through the circulating water pipeline 7 for even spraying. The evaporative heat and moisture exchanger 9, water flows evenly from top to bottom from the surface of the evaporative heat ...

Embodiment 2

[0028] Embodiment 2: when heating:

[0029] The low-temperature and low-pressure liquid refrigerant flows into the finned surface heat exchanger 1 to evaporate through the refrigerant circulation pipe 3 through the refrigerant pipe inlet 11, and then flows into the water-refrigerant heat exchanger 5 through the refrigerant circulation pipe 3 to evaporate into a completely gaseous refrigerant and then passes through the refrigerant pipe Outflow from exit 12;

[0030] Powered by the circulating water pump 6, the relatively high-temperature water is first sent to the water-refrigerant heat exchanger 5 to exchange heat with the refrigerant through the circulating water pipeline 7, and the water absorbed by the refrigerant is then sent to the water distributor 8 through the circulating water pipeline 7 for uniformity Spray to the evaporative heat and moisture exchanger 9, and the water flows evenly from top to bottom from the surface of the evaporative heat and moisture exchanger 9...

Abstract

The invention discloses a compression-type refrigeration and heating outdoor heat exchange device, which includes a refrigerant circulation heat exchange assembly, a water circulation heat exchange assembly and an air convection heat exchange assembly; the refrigerant circulation heat exchange assembly includes a finned surface heat exchanger, a refrigerant, Refrigerant pipeline inlet, refrigerant pipeline outlet, refrigerant circulation pipeline and water-refrigerant heat exchanger, water circulation heat exchange components include circulating water pump, circulating water pipeline, circulating water, water-refrigerant heat exchanger, water distributor, evaporative heat and moisture exchange Air convection heat exchange components include evaporative heat and moisture exchangers, fans and finned surface heat exchangers. The present invention lowers the condensation temperature of the refrigerant during refrigeration, improves the refrigeration efficiency, and fully utilizes the latent heat of the air during heating to improve the heating efficiency. At the same time, the outer surface of the finned surface heat exchanger is clean and the thermal resistance is small; at the same time, it has a simple structure. , less auxiliary equipment, convenient operation and maintenance, etc., can greatly improve the energy efficiency ratio of the unit.

Description

technical field [0001] The invention relates to the technical field of compression refrigeration and heating, in particular to a compression refrigeration and heating outdoor heat exchange device. Background technique [0002] With the development of the economy and the improvement of people's living standards, the requirements of production technology and people's pursuit of quality of life make refrigeration and heating a necessity in the work and life of each of us.
