Double-compressor hybrid-power combustion-gas thermal pump air-conditioning system

Abstract

The invention relates to a dual-compressor mixed power fuel gas heat pump air conditioner, with multifunction, energy-saving and environment-friend properties. Wherein, the system engine (1) is connected to the open compressor (2) via axle or belt; the exhaust tube of open compressor (2) is combined with the exhaust tube of direct-current variable-frequency compressor (9) to connect the oil separator (3); the sucker of open compressor is combine with the sucker of direct-current variable-frequency compressor (9) to connect gas-liquid separator (8); the output of oil separator (3) is connected to the inlet A tube of four-way valve (4); the first output C tube of four-way valve (4) is connected to the gas-liquid separator (8); the second output B tube is connected to the indoor heat exchanger (7); another end of indoor heat exchanger (7) is connected to the throttle device (6); another end of throttle device is connected to the outdoor heat exchanger (5); another end of outdoor heat exchanger is connected to the third output D of four-way valve.

Description

technical field [0001] The invention relates to a novel dual-compressor hybrid gas heat pump air-conditioning system, which belongs to the technical field of air conditioner manufacturing. Background technique [0002] Coal has always been dominant in my country's primary energy consumption. Extensive use of coal has brought serious environmental pollution and brought great pressure to my country's economic development and environmental protection. Natural gas is a kind of green energy. It is clean and can reach a state of complete combustion. Increasing the proportion of natural gas in my country's energy use will help adjust the energy structure. Compared with electric air conditioners, gas air conditioners have obvious comparative advantages in saving energy, reducing air pollution, improving urban environmental quality, adjusting power peak-valley balance rate, and increasing power load rate. Therefore, the popularization and application of gas-fired air-conditioning ha...

AI Technical Summary

Problems solved by technology

[0003] At present, in the application process of gas heat pumps, when the load of the heat pump air conditioning system changes frequently, the fuel engine mainly operates under partial load conditions, and the operating conditions constantly change with the external load, usually deviating from the calibration conditions. The change of working conditions is mainly realized by controlling the size of the fuel flow. With the change of fuel flow, the working conditions of the engine are changing frequently, the engine running stability is poor, and the fuel economy is low; at the same time, although the gas heat pump mainly consumes fuel (such as natural gas, gasoline, etc.), but the fans, pumps and control circuits in the air conditioning system also need additional electric energy to drive, making the gas heat pump dependent on the power supply place, which limits the application range of the gas heat pump
