Total heat exchanger and fresh air handling unit system

Abstract

The invention discloses a total heat exchanger and a fresh air handling unit system. The total heat exchanger comprises moisture absorption grains, cooling medium channel pipes, shunt pipes and a screen mesh, wherein the shunt pipes are symmetrically distributed on the two ends of the total heat exchanger along a longitudinal direction, and multiple cooling medium channel pipes are formed on the total heat exchanger along the longitudinal direction; each cooling medium channel pipe is respectively communicated with the corresponding shunt pipe, and the gap of each cooling medium channel is divided into multiple independent spaces by screen mesh in a horizontal direction; and the moisture absorption grains are filled in the separate independent spaces in a porous medium form. By the total heat exchanger and the fresh air handling unit system provided by the invention, the dehumidification and humidification performances of an air conditioner are enhanced and the operating efficiency of the air conditioner is improved.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a total heat exchanger and fresh air unit system. Background technique [0002] With the continuous improvement of people's living standards, in the living and indoor working environment, the installation of air conditioning system to improve the comfort of living and working environment has become an important choice for people to improve the comfort demand. Among them, multi-connected air-conditioning technology is an important direction for the development of air-conditioning due to its advantages of free control, high efficiency and energy saving, and easy installation and maintenance. [0003] A multi-split air conditioner system generally includes one or more outdoor units, one or more indoor units, and a wire controller. The wire controller is connected to the indoor unit, and the indoor unit is connected to the outdoor unit. The outdoor unit is generally composed of outdoor...

Problems solved by technology

However, there is a pressure difference between the outdoor fresh air of the total heat exchanger and the water vapor partial pressure in the indoor exhaust air. The water vapor passes through the moisture-permeable paper of the core to transfer mass between the fresh air and the return air. The moisture permeability of the internal paper affects the The heat and mass transfer capacity of the total heat exchanger, at the same time, due to the limited mass transfer capacity and speed of this method, the dehumidification and humidification capacity of the total heat exchanger is limited, resulting in insufficient dehumidification in summer and humidification in winter, reducing the performance of the air conditioner. operation efficiency
