Heat source tower based heat pump air-conditioning system and method taking fresh air into consideration

Abstract

The invention discloses a heat source tower based heat pump air-conditioning system and method taking fresh air into consideration. The system comprises a steam compression cycle, a switchable fresh air system, a solution circulation loop, an anti-freezing solution circulation loop and a cooling water circulation loop. The system has a winter operating mode and a summer operating mode, specifically, in winter, the system operates as a typical heat pump system of a heat source tower, and anti-freezing solutions in three filler towers enter an indoor unit to release heat after absorbing heat from air to be heated; and in summer, a steam compression type refrigerating system based on the corresponding filler tower and a solution dehumidification fresh air system based on the corresponding filler towers are adopted, the second and third filler towers are used for the solution dehumidification fresh air system, and the first filler tower operates as a conventional cooling tower and provides cooling water for a condenser. By means of the system and method, a cooling tower, in idle in summer, of the heat pump system of the heat source tower is utilized reasonably, the requirement for summer fresh air treatment cooling capacity is reduced, and an energy tower based heat pump air conditioner capable of obtaining fresh air is obtained.

Description

technical field [0001] The present invention relates to a heat pump air-conditioning system based on an energy tower and taking fresh air into account. It is a method and device for pre-dehumidifying fresh air by using a packing tower idle in summer in a heat source tower heat pump system, and belongs to heat source tower heat pumps, solution dehumidification, and fresh air units. technology field. Background technique [0002] With the continuous improvement of living standards, people's requirements for the comfort of life and work are getting higher and higher, the demand for building cooling and heating is increasing, and the proportion of building energy consumption in the total energy consumption of society is constantly increasing. Therefore, to achieve The energy saving of building air conditioning system has become an important way to alleviate the energy shortage. [0003] The heat source tower heat pump system is proposed to solve the problem of frosting in winte...

AI Technical Summary

Problems solved by technology

Since dehumidification requires air to be processed to the dew point temperature corresponding to the indoor temperature, the fresh air unit consumes a part of cooling capacity for dehumidification

In addition, dealing with latent heat and sensible heat loads at the same time will create a wet surface on the surface cooler, providing an environment for mold growth, which is not conducive to maintaining the quality of fresh air
