Multi-stage cold source swimming pool heat pump dehumidifier and working method thereof

Abstract

The invention discloses a multi-stage cold source swimming pool heat pump dehumidifier and a working method thereof. The multi-stage cold source swimming pool heat pump dehumidifier comprises an air preheater, two or more than two refrigerating circulation systems and an air heater, and the air preheater, the two refrigerating systems and the air heater are sequentially arranged in the air flow direction; in the more than two refrigerating circulation systems which are arranged in parallel, the first refrigerating system is provided with an evaporator and a condenser, and refrigerating or heatpump heating can be achieved; and the second system is provided with a first evaporator and two parallel condensers, and refrigerating dehumidifying, air temperature rising and pool water heating circulating can be achieved. According to the multi-stage cold source swimming pool heat pump dehumidifier and the working method thereof, air can be treated step by step, various energy sources with different kinds of quality are fully utilized, and the purpose of improving the comprehensive energy efficiency is achieved; meanwhile, unit condensation heat is recycled and reutilized, the air feedingstate is adjusted and improved, and the pool hall temperature and humidity and the pool water temperature are adjusted; and in addition, air exhaust energy is recycled and used for lowering the unit condensation temperature or increasing the evaporation temperature, and the energy efficiency is improved.

Description

technical field [0001] The invention relates to the field of dehumidifiers, in particular to a multi-stage cold source swimming pool heat pump dehumidifier and a working method thereof. Background technique [0002] With the continuous improvement of people's living standards, people not only require places where they can swim, but also put forward higher requirements for the swimming environment, and also need to ensure a certain amount of fresh air exchange. Therefore, the temperature and humidity control of indoor swimming pools is increasingly subject Widespread attention. When the relative humidity is too high, the indoor air quality cannot be guaranteed; when the relative humidity is too low, the pool water evaporates too fast, which will undoubtedly increase the input cost. In short, the air quality requirements in the pool hall are getting higher and higher, and the functions of the swimming pool dehumidifier are also demanding more and more. With the widespread us...

Problems solved by technology

The resulting problem is: Generally, the temperature of the cold water is the same as or slightly higher than the evaporation temperature of the refrigeration system, and can no longer bear the heat and humidity load. When the reheating condenser is working, it will cause the process of cooling, dehumidification, reheating, and then cooling. Energy waste

Or the cold water surface cooler can only be started when the compressor is not working. In this configuration, the refrigeration system needs to be configured according to the full load, and the surface cooler also needs to be configured according to the full load, resulting in high initial cost of the unit.

When auxiliary heating from an external heat source is required, the cold water surface cooler cannot be compatible with other heating media other than hot water

When the pool hall needs to be dehumidified and heated up in winter, the rear surface cooling coil cannot meet the requirements at the same time
