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 cooling-and-heating-type air conditioner and a control method thereof. The cooling-and-heating-type air conditioner comprises a double-cylinder compressor, a reversing component, an outdoor heat exchanger and an indoor heat exchanger component, wherein the double-cylinder compressor comprises a first air cylinder and a second air cylinder, and the volume ratio of the first air cylinder to the second air cylinder ranges from 1 to 20; the reversing component comprises exhaust valve ports, a first outdoor connection valve port, a second outdoor connection valve port, a first indoor connection valve port, a second indoor connection valve port, a first air suction valve port and a second air suction valve port; the outdoor heat exchanger comprises one gathering port and two diversion ports; two ends of the first indoor heat exchange part of the indoor heat exchanger component are separately connected with the first indoor connection valve port and one of the diversion ports; and two ends of the second heat exchange part of the indoor heat exchanger component are separately connected with the second indoor connection valve port and the other diversion port. By adopting the cooling-and-heating-type air conditioner disclosed by the invention, the energy efficiency level of the cooling-and-heating-type 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. Background technique [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. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at le...
