Air-freshening, ventilating, air-conditioning and purifying unit with heat recovery function

Abstract

An air-freshening, ventilating, air-conditioning and purifying unit with the heat recovery function comprises an air-conditioning indoor unit heat exchanger, an air-conditioning outdoor unit heat exchanger connected to the air-conditioning indoor unit heat exchanger through a connection pipe, a ventilating unit and an air and air heat exchanger arranged in the ventilating unit; the ventilating unit is provided with an air inlet communicating with the outdoor side, an internal air outlet guided to the outdoor side, an air return port communicating with the indoor side and an internal air supply port guided to the indoor side, gas subjected to heat exchange and output by the internal air supply port of the ventilating unit is guided into an air supply channel and conveyed into the indoor side after sequentially flowing through the air-conditioning indoor unit heat exchanger and an air supplier, and gas subjected to heat exchange and exhausted by the internal air outlet of the ventilating unit is exhausted to the outdoor side after sequentially flowing through an air exhaust channel, the air-conditioning outdoor unit heat exchanger and an exhaust fan. The air-freshening, ventilating, air-conditioning and purifying unit integrates the functions of air freshening, air ventilating, heat recovering, air conditioning and purifying and can be operated stably at the highest temperature in summer or at the lowest temperature in winter, and the energy is saved by more than 40%.

Description

Technical field [0001] The invention relates to an air conditioning purification unit. In particular, it relates to a heat recovery fresh air ventilation air conditioning purification unit. Background technique [0002] In modern buildings, air conditioning is an indispensable device. It provides people with a comfortable working and living environment and also brings a lot of building energy consumption. Part of the air conditioning load comes from the building envelope and indoor personnel and equipment, and part comes from outdoor fresh air. In order to reduce the energy consumption of air-conditioning, more and more new buildings are adopting passive building technology, requiring good airtightness, and selecting fresh air ventilation units with heat recovery function to reduce the air conditioning load of fresh air and indoor air discharge. Energy waste. [0003] The fresh air ventilation unit with heat recovery in the prior art generally includes fresh air fan, exhaust fan...

AI Technical Summary

Problems solved by technology

Therefore, the heat recovery fresh air ventilation unit with the existing structural form and working method cannot fully recover the exhaust air energy from the economic point of view, and cannot fully meet the requirements of indoor air conditioning from the practical point of view.
