Abstract

The invention discloses a super heat recovery fresh air unit. The super heat recovery fresh air unit comprises an air supply fan and an exhaust fan. A compressor, an expansion valve, a heat exchanger, a fan body, a filter screen, a control device, an air inlet, an air outlet, a copper pipe connector, a condensate pipe connector and a metal plate shell are arranged in the air supply fan. The exhaust fan comprises a heat exchanger, a fan body, a copper pipe connector, an air inflow connector, an exhaust connector, an electric cabinet and shell. The air supply fan and the exhaust fan are connected through a copper pipe, and energy at the exhaust part is transferred to the air supply end with Freon under driving of the compressor based on internal Freon circulation similar to the air conditioner principle. Due to the fact that the temperature of indoor air is lower in summer and higher in winter compared with that of outdoor air generally, the overall COP value can be greatly increased, namely, the purpose of heat recovery of indoor air is achieved from the fundamental principle; compared with traditional common plate or runner type heat recovery only depending on the air temperature difference, the heat recovery efficiency of the mode can reach up to 500%-600%.

Description

technical field [0001] The invention belongs to the technical field of central air conditioning, and in particular relates to a super heat recovery fresh air unit. technical background [0002] In recent years, with the improvement of people's material life, people pay more and more attention to the indoor environment, especially the indoor air quality and comfort. Fresh air systems are developing rapidly, especially the large number of fresh air systems currently on the market. However, conventional fresh air systems generally only have the functions of filtration and ordinary heat recovery (generally realized by plate heat exchangers). The heat recovery efficiency depends on the temperature difference between indoor and outdoor, and the supply air temperature cannot be controlled. The temperature of the incoming fresh air is high in summer and low in winter. While greatly affecting the comfort of the human body, it also increases the energy consumption of indoor air cond...
