Fresh air ventilation system with heat recovery function

Abstract

The invention provides a fresh air ventilation system with a heat recovery function. The fresh air ventilation system comprises a machine box, a fresh air fan, an exhaust air fan, a heat recovery heatexchanger, a heat pump heat exchanger set, an electric control box and a remote controller, wherein a partition plate is connected into the machine box, a fresh air inlet and a fresh air outlet are formed in two side walls corresponding to a fresh air partition chamber, and an exhaust air inlet and an exhaust air outlet are formed in two side walls corresponding to an exhaust air partition chamber; the fresh air inlet and the fresh air outlet correspondingly form a fresh air channel; the exhaust air inlet and the exhaust air outlet correspondingly form an exhaust air channel; the fresh air fan is erected at the inner side of the fresh air partition chamber; the exhaust air fan is erected at the inner side of the exhaust air partition chamber; the upper portion of the heat recovery heat exchanger is located in the fresh air partition chamber, and the lower portion of the heat recovery heat exchanger is located in the exhaust air partition chamber; and the heat pump heat exchanger set comprises a compressor, and an outlet is sequentially connected with a fresh air heat pump heat exchanger and an exhaust air heat pump heat exchanger through pipelines. According to the fresh air ventilation system, the heat recovery efficiency can reach 80% or above from 50% to the maximum; and meanwhile, through heat recovery of heat pumps, 100% recovery of air conditioner energy in exhaust air can be realized, additional cold and heat capacity can be generated, and the requirement of a user for the fresh air temperature is met.

Description

technical field [0001] The invention belongs to the technical field of fresh air ventilation, and in particular relates to a fresh air ventilation system with heat recovery function. Background technique [0002] With the improvement of people's material life, the requirements for indoor air quality have also increased significantly. Therefore, regular and quantitative organized ventilation has been paid more and more attention by people, and it has also become an important indicator for evaluating the grade of indoor environment. Therefore, the market for fresh air ventilators will become larger and larger, and it will surely become one of the must-installed equipment for indoor air treatment. [0003] With the improvement of the airtightness of the enclosure structure and the adoption of measures such as minimizing the intrusion of outdoor cold wind in order to achieve the effect of heat preservation, the discharge or dilution of indoor pollutants is not timely. People in ...

Problems solved by technology

Therefore, the size of the fresh air volume has a great influence on the energy consumption of the building. It is necessary to consider both the indoor air quality and the energy consumption. Therefore, using a fresh air ventilator with heat recovery function to ensure the fresh air volume is currently a commonly used method, but the efficiency is generally high. Not high, there is still a part of exhaust heat that has not been recovered
