An energy recovery type intelligent fresh air processing unit

Abstract

The invention discloses an energy recovery type intelligent full fresh air processing unit which comprises a cabinet body, a fresh air inlet, an evaporative condenser, a primarily efficient filter screen, an electric dedusting device, a volute draught fan, a fresh air outlet, a return air inlet, circulating air openings, an inner circulating air valve, a baffle, a condenser, a compressor and a return air outlet. The cabinet body is divided into the air feeding side and the air exhaust side by the vertical baffle, the middle of the air feeding side and the middle of the air exhaust side are provided with the circulating air openings, and the evaporative condenser, the primarily efficient filter screen, the electric dedusting device and the volute draught fan are located on the air feeding side. According to the energy recovery type intelligent full fresh air processing unit, heat of indoor return air can be recycled so that the condensation temperature and the condensation pressure can be changed, energy consumption is reduced, and cross infection caused by traditional heat recovery is avoided; and in haze weather, internal recycle of the unit can be started, the indoor air quality can be maintained, energy consumption is reduced, and different operation modes can be carried out according to different indoor and outdoor environment temperatures, humidity, CO2 concentrations and PM2.5 concentrations.

Description

Technical field: [0001] The invention relates to an all-new fan unit, in particular to an intelligent all-new fan unit with exhaust energy recovery type. Background technique: [0002] At present, air conditioners are widely used in buildings, and fresh air treatment is carried out on the basis of temperature regulation. The direct evaporative fresh air air handling unit has the advantages of simple system, flexible layout, high operating efficiency, and precise temperature and humidity control, especially when it is used as the fresh air system of the VRV air conditioning system, its superiority can be more clearly reflected. However, when the outdoor air temperature is very high, the brand new fan unit cannot get rid of the disadvantages of high compressor discharge temperature and discharge pressure, and low operating efficiency. And the traditional heat recovery fresh air unit will lead to cross-contamination. Secondly, increasing the fresh air volume is a way to impro...
