Air conditioning system capable of regulating temperature and dehumidifying and control method thereof

Abstract

The invention relates to the field of air conditioners and provides an air conditioning system capable of regulating temperature and dehumidifying and a control method thereof. The air conditioning system comprises a compressor unit, an outdoor heat exchanger and indoor large and small heat exchangers. The outdoor heat exchanger, the indoor large heat exchanger, an exhaust port of the compressor unit and an air suction port of a large air cylinder communicate to a first reversing valve; the first reversing valve is used for controlling the outdoor heat exchanger to communicate to the exhaust port of the compressor unit and the air suction port of the large air cylinder alternatively and is used for controlling the indoor large heat exchanger to communicate to the air suction port of the large air cylinder and the exhaust port of the compressor unit alternatively; the indoor small heat exchanger, the air suction port of the compressor unit, the exhaust port of the compressor unit and the first reversing valve communicate to a second reversing valve, and the second reversing valve is used for controlling the outdoor heat exchanger or the indoor large heat exchanger to communicate tothe air suction port of a small air cylinder selectively through the first reversing valve and is used for controlling the indoor small heat exchanger to communicate to the air suction port of the small air cylinder, the air suction port of the compressor unit and the exhaust port of the compressor unit alternatively. The air conditioning system can meet the demands in summer, winter and transition seasons.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system with adjustable temperature and dehumidification and a control method thereof. Background technique [0002] The temperature-humidity separate control air-conditioning system based on high and low temperature dual cold sources is referred to as the dual-temperature air-conditioning system. Realize independent control of indoor temperature and humidity. [0003] The dual-temperature air-conditioning system mainly includes the following advantages: 1. Realize the separation of temperature and humidity control equipment, thereby liberating the temperature restriction on the main cold source of the air conditioner. 2. Through the setting of high and low temperature dual cold sources, more than 85% of the total air conditioning load in summer is borne by high temperature cold sources with a cooling efficiency of more than 8.0, which has a significa...
