Temperature and humidity separated control air conditioner system based on single-machine different evaporation temperatures and control method

Abstract

The invention provides a temperature and humidity separated control air conditioner system based on single-machine different evaporation temperatures. A cold and heat source system, a tail end system,a first water system and a second water system are included. The cold and heat source system comprises a single-machine different evaporation temperature compressor, a first four-way valve, a secondfour-way valve, an outdoor heat exchanger, a liquid vision lens, a drying filter, a first ball valve, a second ball valve, a third ball valve, a fourth ball valve, a first electronic expansion valve,a second electronic expansion valve, a first indoor heat exchanger and a second indoor heat exchanger. The tail end system comprises a temperature control tail end and an energy classified utilizationhumidity control tail end. The first water system comprises a first circulation water pump, a first indoor heat exchanger and a first water circulation loop formed at the humidity treatment section.The second water system comprises a second circulation water pump, a second indoor heat exchanger, a second water circulation loop formed at the temperature control tail end and a third water circulation loop formed by the second circulation water pump, the second indoor heat exchanger, a pretreatment section and a retreatment section. The invention further provides a control method of the air conditioner system.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system with separate temperature and humidity control based on different evaporation temperatures of a single machine and a control method. Background technique [0002] The Yangtze River Basin has high humidity all year round, especially in summer. Considering the comfort and energy efficiency of the air-conditioning system, it is advisable to adopt the temperature-humidity separate control air-conditioning system in this area. The dual evaporating temperature and humidity separate control air conditioning system is more energy-efficient than the traditional air conditioning system. [0003] In my country, the research on air-conditioning systems and machines with dual evaporating temperatures involves many aspects, but there are few studies on air-conditioning systems with separate control of temperature and humidity at different evaporating temperatures. For ...

Problems solved by technology

For example, patent CN102141316A provides a double evaporating temperature air conditioner with independent control of temperature and humidity. This air conditioner can only cool in summer and is suitable for places with small cooling capacity.

[0004] In addition, the dual evaporating temperature air-conditioning system in the prior art also has problems such as complex system structure, high cost, difficult control, and insufficient energy efficiency.
