Air conditioner with gas-aided heating

TLDR: In this paper, a heat-cool air conditioner, which recycles coolant to refrigerate and burns gas to heat, is presented, which can solve the problem that air conditioners can not work in ultra-low temperature, to reduce energy consumption and improve the heat efficiency.

Abstract: The invention discloses a heat-cool air conditioner, which recycles coolant to refrigerate and burns gas to heat. It comprises an indoor unit A and an outdoor unit B; wherein, the unit B contains a compressor, an outdoor fan, an outdoor heat exchanger, a four-way valve and a gas heater; the cool recycle tube between the indoor and outdoor heat exchangers is mounted with a gas heater; the upper part of gas heater is mounted with a smoke cover while the lower part has a burner; the burner is connected to a gas valve; a heat exchanger is between the burner and the smoke cover; one side or two sides of heat exchanger is mounted with a liquid tank; the outer and inner heat tubes form a channel to connect the liquid tank; it uses the thermal transmission of liquid medium of liquid tank to exchange heat; uses the positive recycle of coolant to refrigerate; the passive recycle of coolant and the auxiliary heating of burning gas are used to heat. It can solve the problem that air conditioner can not work in ultra-low temperature, to reduce energy consumption and improve the heat efficiency.
