Embodiment Construction

[0015] figure 1 A compressed air refrigeration system is shown, including a compressor (1), a heat exchanger (2), an expander (3), an electric motor (4) and a circuit control system; the compressed air refrigeration system includes two operating modules, Cooling module (5) and heating module (6).

[0016] When indoor cooling is required in summer, the circuit control system switches the indoor system to the refrigeration module (5), and the indoor hot air A undergoes two-stage adiabatic compression in the compressor (1) to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters from port a The plate heat exchanger (2) performs heat exchange. After heat exchange and cooling, the medium-temperature and high-pressure gas is output from port b, and then enters the expander (3). After adiabatic expansion, it becomes low-temperature and low-pressure gas B, and cold air B of low temperature and low pressure enters Indoor, to achieve cooli...

Abstract

The invention discloses a compressed air refrigeration system. The compressed air refrigeration system mainly comprises a compressor, a heat exchanger, an expansion machine, a motor and a circuit control system, wherein when refrigeration is required indoors in summer, the circuit control system switches an indoor system to be in a refrigeration mode, indoor hot air A enters the compressor, is subjected to adiabatic compression and heating, enters an a port of the heat exchanger, is subjected to heat exchange and cooling at the heat exchanger, is sent out from a b port, enters the expansion machine, and is subjected to adiabatic expansion and cooling, and cold air B is sent into the indoor space; and when heating is required indoors in winter, the circuit control system switches the indoor system to be in a heating mode, indoor cold air C enters a c port of the heat exchanger, and after primary heat exchange, hot air D is sent into the indoor space from a d port of the heat exchanger. According to the compressed air refrigeration system, the heat exchange process of the heating mode is carried out at a high temperature, so that the frosting problem is radically avoided, the heating effect is improved, and the energy consumption is reduced; air is selected as a heat transfer medium, so that the pollution of a synthetic refrigerant to the environment is avoided; and the compressed air refrigeration system can be widely applied to winter heating and summer refrigeration systems, and can be applied to refrigeration systems like refrigerating cabinets and refrigerators as well.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to a refrigeration system for compressing air. Background technique [0002] At present, when the air conditioner enters the heating operation in winter, the heating effect gradually decreases as the external ambient temperature decreases. This is because the heating principle of the air conditioner in winter is that the outdoor unit absorbs heat from the outside air and transmits it to the room through the indoor unit. coefficient, thereby deteriorating the heating effect. [0003] In order to improve the heating effect of the air conditioner in winter, it is necessary to defrost the outdoor unit. Generally, regular defrosting or constant temperature defrosting are adopted, and the heating mode is changed to cooling mode by switching the four-way reversing valve. At this time, the heat exchanger of the outdoor unit acts as a condenser to rel...
