Air conditioner capable of controlling temperature and humidity separately

Abstract

The invention discloses an air conditioner capable of controlling temperature and humidity separately. The air conditioner comprises an indoor unit system positioned on a user side, and an outdoor unit system positioned on an outdoor side, wherein the outdoor unit system comprises a compressor; the compressor is connected with an outdoor side heat exchanger through a four-way valve; the outdoor side heat exchanger is connected with a refrigerant distribution adjustor I; the indoor unit system is partitioned into two modules, namely, a high-temperature module and a low-temperature module; the refrigerant distribution adjustor I is connected with a low-temperature module heat exchanger of the low-temperature module through a low-temperature module expansion valve; the refrigerant distribution adjustor I is connected with a high-temperature module heat exchanger of the high-temperature module through a high-temperature module expansion valve; the high-temperature module heat exchanger is connected with a refrigerant distribution adjustor II; the low-temperature module heat exchanger is connected with the refrigerant distribution adjustor II through a refrigerant boosting device and a one-way adjusting valve; the refrigerant distribution adjustor II is connected with the four-way valve. According to the air conditioner, temperature and humidity can be controlled separately, and the requirement for separate control of temperature and humidity on the indoor side is met; the energy efficiency ratio of the air conditioner can be increased greatly; the refrigerant flows of the high-temperature module and the low-temperature module can be adjusted optionally, so that the requirement of different indoor working conditions are met.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air conditioning, in particular to an air conditioner with independent temperature and humidity control and good energy saving. Background technique [0002] At present, traditional air-conditioning equipment has become the mainstream of room air-conditioning, but the traditional air-conditioning equipment mainly has the following three deficiencies: First, in order to meet the humidity requirements, the transitional cooling to remove excess humidity will cause waste of energy utilization grade; Second, the ratio of sensible heat to latent heat of air treatment is difficult to match with the change of indoor heat-humidity ratio. Sometimes it is necessary to sacrifice the control of humidity to meet the requirements of indoor humidity, and it is difficult to guarantee thermal comfort. [0003] The CN102519099A invention discloses a ground source heat pump unit for temperature and humidity in...

[0002] At present, traditional air-conditioning equipment has become the mainstream of room air-conditioning, but the traditional air-conditioning equipment mainly has the following three deficiencies: First, in order to meet the humidity requirements, the transitional cooling to remove excess humidity will cause waste of energy utilization grade; Second, the ratio of sensible heat to latent heat of air treatment is difficult to match with the change of indoor heat-humidity ratio. Sometimes it is necessary to sacrifice the control of humidity to meet the requirements of indoor humidity, and it is difficult to guarantee thermal comfort.

The air source heat pump unit needs to perform secondary heat exchange. The refrigerant flowing in the pipeline is low-temperature water, and the low-temperature end mainly deals with fresh air. The cooling and dehumidification of fresh air cannot deal with the return air in the room, and the scope of application is small.
