Problems solved by technology

However, the essence of the low heat utilization efficiency of the rotary dehumidifier is that the two processes of dehumidification and regeneration are isenthalpic processes rather than isothermal processes. The humidity and temperature differences between the surface of the rotor and the air are very uneven, resulting in a large irreversible loss

Abstract

The invention discloses a double-effect heat-pump type total-heat recovery fresh air processor, belonging to the energy source utilization technology and air conditioning field. The processor is composed of an air-air heat recovery device, an air exhaust part, a fresh air processing part, a heat recycler and a heat-pump system. The air-air heat recovery device has various types and materials (such as (1) diamond-shaped or hexagonal special paper core, (2) diamond-shaped or hexagonal aluminum core, (3) rotating wheel type, and (4) hot rod type); and the heat-pump part comprises a compressor, a condenser, an evaporator and a throttling valve. The indoor low-temperature low-humidity exhaust air is used for exhausting the condensation heat quantity of a refrigerating system in summer; and the indoor high-temperature high-humidity exhaust air is used for exhausting the evaporation cold quantity of the refrigerating system in winter. The air-air heat recovery device pre-cools or pre-heats the new exhaust air through the heat exchange; and the heat-pump system provides necessary cold quantity and heat quantity for a fresh air processing system.

Description

technical field [0001] The invention relates to a fresh air processor with full heat recovery, in particular to a double-effect heat pump type full heat recovery fresh air processor. Background technique [0002] Most of the air-conditioning systems in civil buildings in my country adopt the mixed mode of fresh return air. Since most of the air circulates indoors, pollutants cannot be discharged outdoors quickly, which is harmful to human health. Increasing the fresh air volume (or adopting fresh air operation mode) can dilute indoor harmful substances and discharge them outdoors, significantly improving indoor air quality. But on the other hand, the increase of fresh air volume greatly increases the energy consumption of fresh air processing. In addition, chilled water or direct evaporation dehumidification methods are mostly used for air treatment. This air-conditioning method has the following disadvantages: 1. The condensation temperature of the air-cooled refrigerator ...
