Refrigerant supercooling heat reusing and recovering air processing unit

Abstract

The invention discloses a refrigerant supercooling heat reusing and recovering air processing unit, an air processing method and an adjusting and control method for all components. The air processing unit comprises a fresh air box, an exhaust air box and a heat pump unit. The fresh air box and the exhaust air box are arranged adjacently. The heat pump unit is arranged in the fresh air box and the exhaust air box. Compared with the prior art, the air processing unit utilizes heat released by refrigerant supercooling under the summer operation working condition, and low-temperature air is heated to the proper air feeding temperature; and the air processing unit utilizes heat released by refrigerant supercooling under the winter operation working condition, outdoor low-temperature air is preheated, return air is prevented from being directly mixed with outdoor fresh air and generating condensed water, and an electric heater which wastes high-grade energy and extra heat sources required by heating of hot water and steam does not need to be arranged; and meanwhile, the heat pump unit of the air processing unit is used for recovering heat of indoor exhaust air, and efficient operation of the air processing unit in summer and winter is achieved.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, in particular to a heat recovery air handling unit for reusing refrigerant supercooled heat. Background technique [0002] With the continuous improvement of the quality of social life, people have higher and higher requirements for the comfort of the indoor environment. The air conditioning system processes the temperature and humidity of the air to meet people's needs. For summer comfort air conditioners, the difference between the air supply temperature of the air conditioner and the indoor temperature should not be greater than 10°C. The primary return air unit processes the air to the dew point temperature. In order to meet the requirements of the temperature difference of the supply air, it usually uses electric heating to reheat the air, and there is an obvious phenomenon of cold and heat offsetting. The secondary return air unit uses the secondary return...

Problems solved by technology

The primary return air unit processes the air to the dew point temperature. In order to meet the requirements of the temperature difference of the supply air, electric heating is usually used to reheat the air, and there is an obvious phenomenon of cold and heat offset

The secondary return air unit uses the secondary return air to reheat the low-temperature air, but there are problems such as complex operation and management, lower dew point, and lower operating efficiency of the unit
