Problems solved by technology

The traditional rotary dehumidification method uses steam, high-temperature hot water and electric heat as renewable energy sources, and the heat energy utilization efficiency is low. The essence is that the two processes of dehumidification and regeneration are isenthalpic processes rather than isothermal processes, resulting in a large irreversible process. loss

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 , The heat pump regenerative runner type total heat recovery humidity control temperature control fresh air unit and its control method are composed of an air-air heat recovery device, a dehumidification runner, an exhaust part, a fresh air processing part and a heat pump system. The number of dehumidification wheels is 12; the heat pump system includes a compressor 1, a four-way reversing valve 2, an evaporator 10, a condenser 3, a condensation heat recovery device 6 and a throttling component 9; the exhaust part is performed by the exhaust fan 4, and the fresh air is processed Partially performed by fresh air machine 7.

[0023] The dehumidification wheel 12 is at the next processing position where the air passes through the evaporator 10 and the condenser 3 of the heat pump system.

[0024] In the heat pump system, through the f...

Abstract

The invention relates to a heat pump regeneration rotating wheel type total heat recovery humidity-adjusting and temperature-controlling fresh air handling unit and a control method of the fresh air handling unit, belonging to the field of energy utilization technology and air conditioning. The fresh air handling unit consists of an air-air heat recovery unit, a dehumidification rotating wheel, an air exhaust part, a fresh air processing part and a heat pump system, wherein the heat pump system comprises a compressor, a condenser, a four-way reversing valve, a condenser, a condensation heat recoverer, an evaporator and a throttling part; the air-air heat recovery unit is utilized to carry out preliminary full heat recovery on new exhaust air, the condensation heat quantity of the heat pump system is utilized to carry out regeneration on the dehumidification rotating wheel, and an exhaust fan brings away the moisture adsorbed by the dehumidification rotating wheel; the evaporator of the heat pump system is utilized to carry out forecooling dehumidification on the fresh air so as to further carry out adsorption type dehumidification on the fresh air through the dehumidification rotating wheel; and a humidifier of the fresh air processing part is utilized to carry out humidification on the dry fresh air. The heat pump system provides the required cold quantity and regenerated heat quantity for a dehumidification system.

Description

technical field [0001] The invention relates to a total heat recovery fresh air unit, in particular to a heat pump regenerative runner type total heat recovery humidity adjustment temperature control fresh air unit and a control method thereof. 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 in fresh air volume greatly increases the energy consumption of fresh air processing, and the fresh air load accounts for about 30%-40% of the total load of air conditioners. In addition, chilled water or direct evaporation dehumidification methods are mostl...
