Different-quality heat recovery refrigerant undercooling and reheating air conditioner and air processing method thereof

Abstract

The invention provides a different-quality heat recovery refrigerant undercooling and reheating air conditioner. The different-quality heat recovery refrigerant undercooling and reheating air conditioner comprises an indoor unit module, an outdoor unit module and a heat pump unit. The indoor unit module further comprises an air supply channel, two exhaust channels and a clean air return channel. The air supply channel comprises a front-section fresh air channel and a rear-section fresh air and returned air mixed air channel. The two exhaust channels are the severe foul air exhaust channel and the mild foul air exhaust channel. In the air inlet direction of the outdoor unit module, an outdoor unit heat exchanger and an outdoor unit exhaust fan are sequentially arranged, the outdoor unit heat exchanger is connected with an outdoor unit fresh air inlet, and the outdoor unit exhaust fan is connected with an outdoor unit exhaust outlet. The invention further provides an air processing method for the different-quality heat recovery refrigerant undercooling and reheating air conditioner. The different-quality heat recovery refrigerant undercooling and reheating air conditioner and the air processing method achieve the purposes that the air conditioner effect is excellent, multiple functions are achieved through one machine, the energy recovery efficiency is high, and cross-contamination is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a subcooling and reheating air conditioner and an air treatment method thereof for heat recovery by mass separation. Background technique [0002] In civil buildings such as passive houses with ultra-low energy consumption and high-end quality, in order to reduce heat loss and the airtightness of the building envelope is better, it is necessary to use fresh air air conditioners to take ventilation measures to effectively purify the indoor air to ensure Good indoor air quality. Indoor air pollutants include physical, chemical, biological and radioactive pollution, which come from indoor and outdoor. In particular, the nature and concentration of air pollutants in different indoor places, such as toilets, kitchens, bedrooms and dining rooms in houses, etc. There is a big difference. At the same time, in order to save energy consumption, it is necessary to recover heat fr...

Problems solved by technology

There are two types of fresh air air conditioners in practical use at present, but both have certain defects: one kind of equipment is that all the dirty air is mixed and then discharged and recovered in a unified manner. The disadvantage of this form is the plate-fin or rotary wheel type total heat recovery Air leakage is inevitable, which will cause indoor cross-contamination; another kind of equipment is to directly discharge the heavily polluted air such as toilets, without heat recovery, and this form will cause energy loss

[0003] In summer, the air supply temperature after the mixed air cooling and dehumidification treatment is low. For this, there are two situations in the fresh air air conditioners that are actually used, but there are certain defects: one is to use electric heating for reheating, which wastes energy; It is to directly supply air to the room at low temperature, which reduces the comfort and is not easy to realize the form of replacement air supply
