Thermoelectric heat regeneration system

Abstract

The invention discloses a thermoelectric heat regeneration system. The thermoelectric heat regeneration system comprises a refrigerating unit and a thermoelectric heat regeneration unit. The refrigerating unit comprises a compressor, an air cooling type condenser, a throttling valve, an air cooling type evaporator and circulating pipelines. The thermoelectric heat regeneration unit comprises a thermoelectric pile, heat exchangers and a bypass branch circuit controller; the hot end and the cold end of the thermoelectric pile are connected with the hot end heat exchanger and the cold end heat exchanger correspondingly; the hot end heat exchanger is connected with the circulating pipeline coming out of the evaporator, heats steam coming out of the evaporator and improves the overheating degree of a refrigerant; the cold end heat exchanger is connected with the circulating pipeline coming out of the condenser, cools liquid coming out of the condenser and improves the overcooling degree of the refrigerant; and the bypass branch circuit controller can control the flow rate of the refrigerant passing through the heat exchangers and widens the heat exchange range. Compared with a traditional heat regenerator, the thermoelectric heat regeneration system can accurately adjust and control the overcooling degree and the overheating degree of the refrigerant and has the beneficial effects of being small in size, simple in structure, easy to install, convenient to control, free of noise and environment-friendly.

Description

technical field [0001] The invention belongs to the field of air conditioning and cold storage refrigeration, and more specifically relates to a thermoelectric heat recovery system. Background technique [0002] The world is facing an energy crisis. On the one hand, it is necessary to develop new energy sources, and on the other hand, energy-saving management of existing products is required. At present, "energy saving and emission reduction" is an important topic in the eyes of all countries in the world. As a major energy consumer, building energy consumption accounts for about 1 / 3 of the total energy consumption of society, and heating and air conditioning energy consumption accounts for about 40% of building energy consumption. %. With the development of urban construction, the proportion of air-conditioning energy consumption in civil energy consumption will also increase, so in the research of air-conditioning systems, energy-saving research has very important economi...

Problems solved by technology

However, the subcooling temperature difference that can be realized by the current regenerator is low, and the improvement of COP (Coefficient of Performance, coefficient of performance) is small, so it is difficult to ensure that the COP is in the optimal state at all times. will significantly reduce the cooling capacity
