Problems solved by technology

[0004] Due to differences in seasons and users’ requirements for comfort, it is necessary to adjust the indoor humidity in a timely manner, and there is even a need to turn on the air conditioner for dehumidification in transitional seasons, and to turn on the air conditioning unit in transitional seasons, because the actual demand for cooling load in the room is very small. It is easy to cause low temperature (or low pressure) protection of the unit during dehumidification operation. In severe cases, freezing will damage the system and cause the unit to fail to operate normally. It is becoming more and more important to provide a dehumidification safe operation system for passive houses to meet the different needs of customers.

Abstract

The invention relates to a dehumidification safety operation system for an air conditioner unit used in a passive house, which includes an outdoor unit system composed of a compressor, a gas-liquid separator, a first four-way valve, a second four-way valve and an environmental heat exchanger, and an indoor An indoor unit system composed of a heat exchanger, a heater, a first one-way valve, a second one-way valve, a third one-way valve, a fourth one-way valve, a fifth one-way valve and a liquid reservoir. The invention can not only meet the user's indoor temperature and humidity requirements, ensure the safe and reliable operation of the unit, but also reduce the interference of human factors, and realize intelligent control operation.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to a dehumidification safety operation system for an air-conditioning unit used in a passive house. Background technique [0002] "Passive house" refers to an ecological building that basically does not need to actively supply energy. Because of its high heat insulation and airtightness, the annual primary energy consumption for cooling and heating is very low. However, due to seasonal changes and the need for ventilation, there is heat and moisture exchange and energy loss. Therefore, a passive house needs a set of active Equipment for cooling and heating and dehumidification functions. [0003] The ducted air conditioner produces air-conditioned cold or hot air according to the Carnot cycle principle, and then sends it to each terminal equipment through the air supply module to realize the adjustment of the indoor temperature. [0004] Due to differences in seasons and users’ requir...
