Abstract

The invention relates to an air conditioning system for independently controlling temperature and humidity, belonging to the air conditioning system field, which comprises an evaporator, an expansion valve, a condenser, a compressor, a gas-liquid heat exchanger, a condensing heat exchanger, a solution regeneration device, a valve 1 to 5, a heat exchanger and a connecting pipeline. The system recovers heat dissipating capacity of the condenser of an air source heat pump unit, and the heat dissipating capacity is used as the heat of the solution regeneration in order to realize the regeneration of desiccant solution, which reduces the requirements of the solution regeneration on other waste heat. The invention saves energy in the regeneration process of the desiccant solution, improves the energy efficiency ratio of the air conditioning system, has the simple structure, and reduces the heat pollution of the environment.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system with independent temperature and humidity control. Background technique [0002] The air-conditioning system with independent temperature and humidity control is a new type, high-efficiency, and energy-saving air-conditioning system. It can realize independent control of temperature and humidity. The humidity control uses a solution dehumidification system. At the same time, the solution dehumidification has a good bactericidal effect, which is conducive to improving the quality of the indoor environment. The solution dehumidification system part of the system generally uses low-grade heat energy as the heat energy for solution regeneration. In summer, if there is sufficient low-grade heat near the air-conditioning system, using this heat as the heat required for solution regeneration can significantly reduce the overall power consumption of the air-conditi...
