Self-coupling heat exchange and cold heat recovery fresh air dehumidification air conditioner

Abstract

The invention provides a self-coupling heat exchange and cold heat recovery fresh air dehumidification air conditioner. The self-coupling heat exchange and cold heat recovery fresh air dehumidification air conditioner is composed of a machine box, an air filter, a heat exchanger, an fresh air damper, an aeration damper, a return air damper, an exhaust damper, an aeration fan, a dehumidification fan, a heat source fan, a dehumidification surface air cooler, a heat source surface air cooler, a four-way valve, an expansion valve, a compressor and a refrigerant pipeline. A wind-separating angle slab, a fresh air inlet chamber, an aeration chamber, a return air chamber, a clean air chamber, a preheating pre-cooling chamber, a dry fresh air chamber and a heat returning and cold returning chamberare mainly arranged in the machine box. Self-coupling heat exchange is carried out on heat and cold of a heat pump through the heat exchanger to achieve the purpose of improving the heat pump performance and energy saving, and efficient recovering and energy-saving are carried out on the cold or heat of the exhaust air through the heat pump. The self-coupling heat exchange and cold heat recoveryfresh air dehumidification air conditioner has the characteristics of high energy efficiency ratio, large dehumidification capacity, high comfort of an air conditioner and no moisture condensation ona fresh air outlet.

Description

[0001] Technical field [0002] Self-coupling heat exchange and cold and heat recovery fresh air dehumidification air conditioner involves an air conditioning system, especially a self-coupling heat exchange through the heat exchanger to perform self-coupling heat exchange on the cold or heat of the heat pump itself, so as to improve the performance of the heat pump and save energy. Through The heat pump efficiently recovers the cold or heat of the exhaust air and saves energy, and is a device that can simultaneously meet the requirements of fresh air, dehumidification, and heating and cooling air conditioning. Background technique [0003] As we all know, the climate in subtropical regions is cold and humid in winter, humid in spring, hot in summer and dusty in autumn. If there is no clean and dry fresh air introduced into the room, and there is no heating and cooling air conditioner to adjust the temperature, humidity and CO2 will be generated indoors. 2 The concentration is...

Problems solved by technology

[0011] At present, there is no four-season solution for fresh air, dehumidification, and heating and cooling in nearly zero buildings. It is a combination of high-cost fresh air dehumidifiers and cooling and heating air conditioners. There is no low-cost four-season solution for fresh air, dehumidification, and heating and cooling.
