Abstract

A heat pump coupling contraflow type liquid-desiccant central ventilation system and control method thereof comprise a heat pump system and a liquid-desiccant and fresh air regeneration processing system, wherein the heat pump system comprises a compressor, a four-way directional control valve, a condenser, an evaporator and a throttle member; the liquid-desiccant and fresh air regeneration processing system comprises a fresh air processing module, a liquid regeneration module, a heat exchanger and a liquid pump; both the fresh air processing module and the liquid regeneration module are serially connected with the pipes by the two liquid heat exchangers through a liquid pool. The fresh air processing module is arranged in an indoor air inlet; the liquid regeneration module is arranged in an indoor air outlet to recycle the energy of the indoor exhaust wind. The invention adopts liquid-desiccant to process the fresh air of the air conditioner and removes the dust and the bacteria in the air through spraying the liquid so as to purify the air. The system can recycle the energy of the indoor exhaust wind, which reduces the energy for processing the fresh air; the heat pump is used for providing energy for the liquid to make use of the low-grade heat source.

Description

technical field [0001] The invention relates to a solution dehumidification fresh air system, in particular to a heat pump coupled countercurrent solution dehumidification fresh air system and a control method thereof. Background technique [0002] Most of the air-conditioning systems in civil buildings in my country adopt the mixed mode of fresh return air. Since most of the air circulates indoors, pollutants cannot be discharged outdoors quickly, which is harmful to human health. Increasing the fresh air volume (or adopting fresh air operation mode) can dilute indoor harmful substances and discharge them outdoors, significantly improving indoor air quality. But on the other hand, the increase of fresh air volume greatly increases the energy consumption of fresh air processing. In addition, refrigeration and dehumidification are mostly used for air treatment at present. This air-conditioning method has the following disadvantages: 1. The air needs to be lowered to the dew ...
