an air conditioning system

Abstract

The present invention provides an air conditioning system, wherein the first ports of the first four-way reversing valve and the second four-way reversing valve are respectively connected to the exhaust port of the two-cylinder compressor; One port of the liquid tank is respectively connected to the two compression chambers of the compressor, and the other port is respectively connected to the second port of the first four-way reversing valve and the second port of the second four-way reversing valve; the second port of the outdoor heat exchanger One port is respectively connected to the third port of the first four-way reversing valve and the third port of the second four-way reversing valve; one port of the first indoor heat exchanger and the second indoor heat exchanger are connected to the outdoor heat exchanger The second port, the other port is connected to the fourth port of the first four-way reversing valve and the fourth port of the second four-way reversing valve; wherein, the first four-way reversing valve and the second four-way reversing valve There are two conduction states, one is that the first interface communicates with the third interface, the second interface communicates with the fourth interface, and the other is that the first interface communicates with the fourth interface, and the second interface communicates with the third interface.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a split cooling and dehumidifying air conditioning system. Background technique [0002] Air conditioning dehumidification is also a very important function of the air conditioner. In fact, the principle of dehumidification of the air conditioner is the same as that of refrigeration. It also relies on the operation of the entire refrigeration system, using the compressor to cool down, and the indoor unit fan to discharge the water in the room to the outside. [0003] The dehumidification function of the air conditioner means that the humidity in the air during the rainy season is relatively high, which can easily cause the indoor walls to "sweat", the clothes are damp, and people feel depressed. At this time, using the dehumidification function can help remove the moisture in the room, so that the room is dry and people feel comfortable. [0004] In summer, there is a lot of humidi...

AI Technical Summary

Problems solved by technology

[0007] In the cooling mode of the traditional refrigeration and air-conditioning system, it undertakes two functions of cooling and dehumidification at the same time. In order to achieve dehumidification, the evaporation temperature is blindly lowered, resulting in lower system energy efficiency and lower human comfort.
