Abstract

A fresh air unit with an air supplying and heat recovering device relates to a fresh air unit and solves problems of counteraction between cold energy and heat energy and high energy consumption, which exist in air treating process of a reheating type air supplying system. The fresh air unit also comprises the air supplying and heat recovering device; one end of a fresh air pipeline is communicated with the air supplying and heat recovering device; two ends of a second connecting pipeline are communicated with the fresh air pipeline and an air discharging and heat recovering device; two ends of a first connecting pipeline are communicated with the air supplying and heat recovering device and the second connecting pipeline; a first air amount regulating valve is arranged on the fresh air pipeline between the second connecting pipeline and the air supplying and heat recovering device; a second air amount regulating valve is arranged on the second connecting pipeline; and an air supplyingsection is communicated with the air supplying and heat recovering device by a third connecting pipeline. By taking advantage of the air supplying and heat recovering device, the invention effectively solves the problem of counteraction between cold energy and heat energy and reduces energy consumption of the system.

Description

technical field [0001] The invention relates to a fresh air processing unit. Background technique [0002] The fresh air processing unit is a common equipment in the air conditioning system and has been widely used in various central air conditioning systems. The air supply methods of the existing fresh air processing units are generally divided into two types: dew point air supply and reheat air supply. But both approaches have problems to varying degrees. The main problems of the dew point air supply system are: 1. The temperature and humidity are coupled with each other, and the adjustment performance is poor, so it is difficult to strictly control the temperature and humidity; 2. The temperature difference of the air supply is large, the air supply volume is small, and the room temperature is uniform. 3. The dew point temperature achieved by the air cooling treatment is low, resulting in a low coefficient of performance of the refrigeration system. The main problem of...
