Abstract

The invention relates to a low-temperature type fuel gas heat pump air-conditioning system and a control method thereof. The low-temperature type fuel gas heat pump air-conditioning system comprises arefrigerant circulation loop which is composed of compressor, an oil separator, a four-way valve, an indoor unit heat exchanger, an outdoor unit heat exchanger and a gas-liquid separator which are connected in sequence. The compressor is connected with a fuel gas engine through a belt; a cooling water tank is disposed outside the fuel gas engine; the cooling water tank forms a cooling water circulation loop through a water pump and a radiator; an auxiliary evaporator is further included; a refrigerant side outlet pipe of the auxiliary evaporator is connected with the gas-liquid separator, anda refrigerant side inlet pipe of the auxiliary evaporator is connected to a pipeline between a second end of the indoor unit heat exchanger and a first end of the outdoor unit heat exchanger; the twoends of a water way of the auxiliary evaporator are connected with the two ends of the radiator correspondingly; and the first end of the outdoor unit heat exchanger is connected with an outlet of the oil separator. By means of the low-temperature type fuel gas heat pump air-conditioning system and the control method thereof, the effect of heating running of the system under the low temperature can be effectively improved, and the unfavorable influences caused by insufficient power supply can be avoided.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system capable of effectively improving the heating operation effect of the system at low temperatures, in particular to a low-temperature gas heat pump air-conditioning system and a control method thereof. Background technique [0002] Existing air conditioners use electricity to drive compressors to operate, thereby forming a cooling or heating cycle. [0003] With the rapid development of urbanization and the rapid increase of civil and industrial electricity consumption, the phenomenon of power shortage is becoming more and more obvious. As a large electricity consumer, air conditioners urgently need to seek improvements to avoid impacts on users due to insufficient power supply. [0004] At the same time, when the ambient temperature is low in winter, the heating effect of the air conditioner will also decrease accordingly. The current common practice is to...
