Problems solved by technology

[0002] Generally, when the air conditioner is cooling, the refrigerant throttled by the throttling element directly enters the indoor heat exchanger for heat exchange. Since the throttled refrigerant is mixed with a part of gaseous refrigerant, it enters the indoor heat exchanger for heat exchange. The gaseous refrigerant in the heater not only affects the heat exchange effect of the indoor heat exchanger, but also increases the compression power consumption of the compressor and reduces the energy efficiency ratio of the compressor, thus affecting the energy efficiency level of the air conditioner

Abstract

The invention discloses a cold and warm air conditioner and a control method. The cold and warm air conditioner comprises a double-cylinder compressor, a reversing assembly, an outdoor heat exchanger and an indoor heat exchanger assembly; the double-cylinder compressor comprises a first air cylinder and a second air cylinder, the value of the volume ratio of the first air cylinder to the second air cylinder ranges from 1 to 20, the reversing assembly comprises an exhaust valve port, a first outdoor connecting valve port, a second outdoor connecting valve port, a first indoor connecting valve port, a second indoor connecting valve port, a first air suction valve port and a second air suction valve port; the indoor heat exchanger assembly comprises a first indoor heat exchange portion and a second indoor heat exchange portion, the two ends of the first indoor heat exchange portion are connected with the first indoor connecting valve port and the second end of a heat exchange flow way, and the two ends of the second indoor heat exchange portion are connected with the second indoor connecting valve port and the second end of the heat exchange flow way. According to the air conditioner, the energy efficiency level of the cold and warm air conditioner can be optimized, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heating and cooling air conditioner and a control method capable of improving the energy efficiency of the air conditioner.
