Heat pump system of heat humidity independent control driven by condensation waste heat and based on solid dehumidification

Abstract

The invention provides a heat pump system of heat humidity independent control driven by condensation waste heat and based on solid dehumidification. The heat pump system provided by the invention comprises a first fan, a second fan, a first dehumidification heat exchanger, a second dehumidification heat exchanger, a first air regulating valve, a second air regulating valve, a compressor, an expansion valve, a bidirectional four-way valve, a first air duct, a second air duct and a refrigerant circulation pipeline, wherein the surfaces of the first dehumidification heat exchanger and the second dehumidification heat exchanger are provided with solid dehumidification materials. According to the invention, the humidity load in air is processed by the solid dehumidification materials arranged on the surfaces of the dehumidification heat exchangers, the processing of air heat load is realized through the cooling mode of the traditional evaporator; and the separation processing and independent control of the heat humidity load are realized only by adopting one device according to the invention, compared with the traditional composite heat humidity independent control heat pump air-conditioning system, the heat pump system provided by the invention has the obvious advantages of simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air-conditioning systems, in particular to a heat pump system driven by condensing waste heat and based on solid dehumidification with independent control of heat and humidity. Background technique [0002] In recent years, with the improvement of people's living standards and the frequent appearance of extreme environments around the world, the widely used traditional vapor compression heat pump air-conditioning system has become the main source of electricity consumption in the whole society. In addition, while the vapor compression heat pump air conditioning system cools the room by cooling the evaporator side, it will generate waste heat higher than the ambient temperature on the condenser side and discharge it into the outside air, resulting in a more significant urban heat island effect. Therefore, it is of great significance to develop low energy consumption technology in the fie...
