Efficient energy-saving multi-stage heat and humidity treatment air conditioning device and treatment method thereof

Abstract

The invention discloses an efficient energy-saving multi-stage heat and humidity treatment air conditioning device and a treatment method thereof. The device comprises a refrigeration circulation component, an air circulation component, and an air heat and humidity treatment component. The refrigeration circulation component comprises a high-temperature stage refrigerator unit, a low-temperature stage refrigerator unit, a high-temperature stage refrigerant delivery pump, a high-temperature stage refrigerant circulation pipeline, a low-temperature stage refrigerant delivery pump, a low-temperature stage refrigerant circulation pipeline, a high-temperature stage primary cooling and dehumidifying refrigerant supply automatic regulating valve, a low-temperature stage secondary cooling and dehumidifying refrigerant supply automatic regulating valve, and a high-temperature stage cooling refrigerant supply automatic regulating valve. Aiming at the defects that the conventional air heat and humidity treatment is substantially high in energy consumption, severe in resource waste, and pollutive to environment, or the like, a reasonable air heat and humidity treatment device is provided, accordingly increasing the utilization ratio of energy resources, reducing the resource waste, reducing the emission, and protecting the environment.

Description

Technical field [0001] The invention relates to a central air conditioning air heat and humidity treatment technology, in particular to a high-efficiency energy-saving multi-stage heat and humidity treatment air conditioner and a treatment method thereof. Background technique [0002] The heat and moisture treatment of the central air-conditioning system in our country mostly adopts the mixing of fresh air and return air and then the heat and humidity treatment, that is, about 20% of the fresh air is mixed with about 80% of the return air, and then the surface is cooled and dehumidified to the room. Need humidity below the dew point temperature (usually <10°C), and finally the air is heated to the supply air temperature (usually about 20°C) by reheating and then sent into the room. [0003] Due to the addition of fresh air, in order to maintain the balance of the indoor air pressure, the excess indoor air needs to be exhausted to the outdoors. Currently, it is mostly directly e...
