Air conditioner

Abstract

The invention discloses an air conditioner. The air conditioner comprises a compressor, an indoor side heat exchanger, an outdoor side heat exchanger, a throttle device, a four-way valve, a reversingassembly and a connecting tube, wherein a compression assembly of the compressor is provided with a first gas suction hole, a first gas exhaust hole, a second gas suction hole and a second gas exhausthole; a first gas cylinder and a second gas cylinder are connected in series; a connecting channel is arranged between the first gas exhaust hole and the second gas suction hole; the outer side heatexchanger comprises at least two outdoor heat exchange units which are arranged in parallel; the throttle device is separately connected to the indoor side heat exchanger and the outdoor side heat exchanger; the reversing assembly comprises at least two switchover valves; the reversing assembly is connected between the outdoor side heat exchanger and a third valve port of the four-way valve; and one end of the connecting tube is connected to the reversing assembly, and the other end of the connecting tube is connected to the first gas exhaust hole. The air conditioner provided by the embodiment of the invention reduces influences, on an indoor temperature, of the air conditioner in a heating defrosting process, improves defrosting effect and comfort of the air conditioner, and reduces defrosting energy consumption of the air conditioner.

Description

Technical field [0001] The present invention relates to the field of air conditioning equipment, in particular to an air conditioner. Background technique [0002] The traditional air conditioner system is mainly composed of a compressor, a condenser, a throttle valve, and an evaporator. A four-way valve is added for the cooling and heating switch to make the condenser and the evaporator interchangeable to realize the cooling and heating switch. In the heating process, the surface of the outdoor heat exchanger will be frosted, and the frost will affect the heat exchange performance of the outdoor heat exchanger. When the frost on the outdoor heat exchanger needs to be removed, the four-way valve needs to be reversed. At this time, the condenser and the evaporator are interchanged, and the indoor heat absorption is used to melt the frost of the condenser, which will reduce the indoor heating effect , Affecting comfort. [0003] In view of the effect of the defrosting process on th...

Problems solved by technology

When the frost on the outdoor heat exchanger needs to be removed, the four-way valve needs to be reversed. At this time, the condenser and the evaporator are interchanged, and the indoor heat is used to melt the frost on the condenser, which will reduce the indoor heating effect. , affecting comfort

[0003] As the defrosting process will affect the indoor temperature, the researchers improved the existing air conditioner, such as adding an electric heater to the outdoor heat exchanger, although this method can defrost the outdoor heat exchanger without affecting the room temperature. frost, but the energy consumption of electric heating is high, and the defrosting efficiency is low

[0004] In view of the above problems, we need a system that can realize that the indoor temperature will not be greatly affected during the heating and defrosting process, and the abnormal throttling noise in the room caused by the shutdown of the air conditioner will not affect the use of the air conditioner. Continual heating and defrosting air conditioners with higher defrosting efficiency and lower energy consumption
