Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Referring to the accompanying drawings, the present invention relates to a storage management software system based on a mobile phone client. The system includes five parts: a compressor, a working medium, an evaporator, a cold and heat exchanger, and a throttling device; it is characterized in that: the air source heat pump Working procedure The low-temperature and low-pressure air-side heat exchanger absorbs the heat in the air and evaporates; the refrigerant becomes a low-temperature and low-pressure gas, which is then compressed by a compressor through a small amount of electric energy input; the high-temperature and high-pressure gaseous refrigerant Heat exchange with the cold water in the exchanger; the high-pressure liquid refrigerant is decompressed through the throttling mechanism; the cold water is heated until the hot water of the required temperature ...

Abstract

The invention relates to an ultra-low temperature heat-exchange device of an air source unit. The ultra-low temperature heat-exchange device of the air source unit comprises a compressor, a working medium, an evaporator, a cold-heat exchanger and a throttling device. The ultra-low temperature heat-exchange device of the air source set is characterized in that as for the working procedure of an air source heat pump, a low-temperature and low-pressure air-side heat exchanger absorbs heat in air for evaporation; refrigerant becomes low-temperature and low-pressure air, and the air is compressed by the compressor via a small amount of power input; the high-temperature and high-pressure gaseous refrigerant performs heat exchange with cold water in the cold-heat exchanger; the high-pressure liquid refrigerant is subjected to pressure reduction through the throttling mechanism; and the cold water is heated till becoming hot water with the needed temperature, and the hot water is stored in a heat-insulating hot water tank. According to the ultra-low temperature heat-exchange device of the air source unit, the vertical top exhaust design is adopted, the unit is small, other rooms do not need to be additionally arranged, and project installation is simple; the intelligent control and defrosting functions are achieved; multiple measures like indirect heating and water-electricity separation are included, and no potential safety hazard exists; and the power-off automatic memory function is achieved, the unit is started to run automatically after power is on, and the unit does not need to be specifically guarded.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an ultra-low temperature air source group heat exchange device. Background technique [0002] At present, the structural connection direction of the centrifugal compression refrigeration unit cannot be selected. When cleaning, inspecting and maintaining the heat exchange tubes, the workload is heavy and the required maintenance space is also large. The space on site often cannot meet the requirements. Contents of the invention [0003] The ultra-low temperature air source group heat exchange device provided by the present invention realizes no huge oil separation device, the unit size and weight are small, and the whole unit has no oil supply system, which fundamentally solves the problem of oil return in the system and avoids the failure of the compressor to lose oil . [0004] The present invention solves technical problem and provides following scheme: [0005] The...
