Central air-conditioning system combining independent regulation of temperature and humidity of heat recovery solution of screw machine

Abstract

The invention relates to a central air-conditioning system combining the independent regulation of the temperature and humidity of heat recovery solution of a screw machine. The central air-conditioning system consists of a two-stage heat recovery circular regenerated solution system of the screw machine, an air-conditioning temperature reduction water system, a temperature reduction and dehumidification air conditioner processing system and a central air-conditioning comprehensive integration control system which combines the independent regulation of the temperature and humidity of two-stage heat recovery regenerated solution of the screw machine, wherein solution for temperature reduction and dehumidification is filled into the circular regenerated solution system; clean water is filled into the air-conditioning temperature reduction water system; and superconducting solution is filled between a heat exchanger and a solution regenerator. In the central air-conditioning system whichcombines the independent regulation of the temperature and humidity of heat recovery solution of the screw machine, the regenerated solution is subjected to two-stage heat recovery by utilizing the high-temperature exhaust gas of a screw air conditioner to be used for the dehumidification of a temperature reduction and dehumidification air conditioner; and the temperature is reduced by using the original air-conditioning water system, so the energy for the dehumidification is reduced, the temperature of the air-conditioning water for the temperature reduction is raised, the efficiency of an air-conditioning host is improved, and the consumption of a water pump, a cooling power and the air-conditioning host of the original air-conditioning water system is reduced greatly.

Description

technical field [0001] The invention relates to a central air-conditioning system, in particular to a central air-conditioning system which can independently adjust the temperature and humidity of a heat recovery solution combined with a screw machine. Background technique [0002] At present, the application of solution cooling and dehumidification in central air conditioning has been vigorously used and promoted in the air conditioning industry, and has been recognized by most experts and scholars in the academic circle. In actual use, due to the significant energy saving effect, it has played a very good role in the energy saving of central air conditioning. However, the existing solution-type temperature and humidity independent humidity control units are all independent equipment, driven by electric energy. The refrigerant circuit needs to increase the power load, and the equipment is too large to be widely used, and the optimal system energy saving cannot be achieved. ...
