Ice-storage cold-heat pump coupled multi-stage total-heat recovery fresh air processor

Abstract

The invention discloses an ice-storage cold-heat pump coupled multi-stage total-heat recovery fresh air processor, belonging to the energy source utilization technology and the air adjusting field. The processor consists of an air exhaust part, a fresh air processing part, a total-heat recoverer and a heat pump system. The heat pump system comprises a compressor, a condenser, a condensation heat recoverer, an evaporator and an expansion 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 total-heat recoverer performs multi-stage total-heat recovery of fresh air and exhaust air so as to improve the heat recovery efficiency. The heat pump system provides necessary cold quantity and heat quantity to a fresh air processing system. The ice-storage cold provides the low-temperature frozen water to completely dehumidify the fresh air so as to achieve lower moisture content.

Description

technical field [0001] The invention relates to a fresh air processor with full heat recovery, in particular to an ice storage cold heat pump coupling multi-stage full heat recovery fresh air processor. [0002] Background technique [0003] 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 o...

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, and there is also cross-contamination between fresh air and exhaust air
