Problems solved by technology

[0003] Compared with the indoor environment of ordinary buildings, the indoor environment of large bathrooms is a high-temperature and high-humidity environment. During operation, a large amount of water vapor will be generated. The air to be discharged has the characteristics of high humidity and high temperature. The composition of the discharged air that requires waste heat recovery is complex. Therefore, the gas must be treated before waste heat recovery. Filtration and dehumidification has become the key to air treatment. If the indoor exhaust air volume is small, the indoor temperature comfort will be guaranteed, but i

Abstract

The invention provides a recycling system for exhaust waste heat of a shower room. The system comprises an exhaust system, an air inlet pipeline and a waste heat recovery system. The exhaust system comprises an exhaust pipeline, a first fan, a first low efficient filter and a membrane separator. The waste heat recovery system comprises a compressor, an evaporator, a condenser and an expansion valve, and the condenser is arranged in the air inlet pipeline; air exhausted in shower room from the first fan successively passes through the first low efficient filter, the membrane separator and the evaporator through the exhaust port of the exhaust pipeline; the evaporator is connected to the inlet of the compressor, the outlet of the compressor is connected to the condenser, and the condenser is connected to the evaporator through the expansion valve. According to the recycling system for exhaust waste heat of the shower room provided by the invention, high humidity air exhausted from the shower room is initially filtered and dehumidified and the humidity of gas is reduced, so that the waste heat recovery standard is met. The waste heat in exhaust of the shower room is effectively recovered and utilized for pre-heating fresh air in the shower room, so that the energy consumption is reduced and the energy resource is saved.

Description

technical field [0001] The invention relates to an exhaust system, in particular to a bathroom exhaust waste heat recycling system. Background technique [0002] As the world pays more and more attention to building energy conservation and the world oil crisis continues to emerge, waste heat recovery has become a new direction of energy conservation research. A good waste heat recovery system can re-collect and utilize waste heat and waste heat. As we all know, the indoor environment of the bathroom is very complicated, and high humidity and high temperature become its main characteristics. Controlling the indoor environment of the bathroom to ensure the comfort of the indoor personnel is an important part of the bathroom. [0003] Compared with the indoor environment of ordinary buildings, the indoor environment of large bathrooms is a high-temperature and high-humidity environment. During operation, a large amount of water vapor will be generated. The air to be discharged ...
