Total-heat-exchange fresh air system

Abstract

The invention provides a total-heat-exchange fresh air system, and relates to the field of fresh air ventilator systems. The total-heat-exchange fresh air system comprises a fresh air ventilator box,a first air supply tube, a first exhaust tube and phase-change heat-exchange assemblies. The phase-change heat-exchange assemblies are separately arranged on the inner wall of the first air supply tube and the inner wall of the first exhaust tube. The first air supply tube is connected with the fresh air ventilator box, communicates with the fresh air ventilator box, and is used for delivering outdoor air to the fresh air ventilator box after the outdoor air is subjected to first-time temperature change effect through the phase-change heat-exchange assemblies; and the fresh air ventilator boxis used for carrying out second-time temperature change effect on the outdoor air, and the first exhaust tube is connected with the fresh air ventilator box, communicates with the fresh air ventilatorbox, and is used for delivering the outdoor air to an indoor environment after the outdoor air is subjected to third-time temperature change effect through the phase-change heat-exchange assemblies.The total-heat-exchange fresh air system has high temperature regulation and control ability, and can efficiently utilize energy generated by diurnal temperature variation; load is further reduced; and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of fresh air system, in particular to a total heat exchange fresh air system. Background technique [0002] The full heat exchange fresh air system uses the temperature difference between the fresh air and exhaust air and the partial pressure difference of water vapor to recover sensible heat and latent heat, which can reduce or increase the temperature of the air entering the room, reducing the air conditioning load by about 57% in summer. Increase by about 64% in winter to achieve the purpose of energy saving and environmental protection. [0003] However, the existing full heat exchange fresh air system still has the following disadvantages: (1) it only achieves energy recovery of the passing gas, which has certain limitations; (2) a small amount of gas will leak through the sealing ring of the partition plate, resulting in energy (3) Improper protection during installation will affect the operation effect of the ...
