Design of constant humidity pool air energy heat pump

In the constant temperature pool water treatment equipment, DC inverter swimming pool heat pump with its energy-saving, efficient, stable operation and other significant characteristics favored by the public swimming pool and private swimming pool users. It ensures that customers can enjoy a constant and comfortable pool water temperature all year round. Let's introduce the constant humidity pool air source heat pump design tutorial in detail.

• Humidity and temperature

• Prioritizing pool water temperature

Humidity and temperature

Constant humidity pool moisture load is large, generally speaking, constant humidity pool ceiling is higher. There is a lot of water evaporation pool water, discharge pool humidity, and heat required by the air volume is very large, so in the DC inverter swimming pool heat pump load is very large. Constant humidity pools generally use floor glass, so the winter DC inverter swimming pool heat pump envelope structure is very easy to condensation. In addition, the pool should use natural lighting, because the glass area is large, so in winter, due to the indoor temperature of the pool and the outdoor environment temperature difference, the dew point is high, so the outdoor cold air is easy to condense in the enclosure structure. Too high humidity is harmful to human health because the pool water should be disinfected with liquid chlorine. The water containing chlorine is released into the indoor air. When the content exceeds 1ppm, it will be harmful to human health. The loss of heat is large, due to the damage caused by chlorine gas to people and things, so the DC inverter swimming pool heat pump adds a lot of outdoor fresh air. In winter, the outdoor fresh air temperature is low, and a lot of heat is needed to heat it to reach the indoor state point.

Prioritizing pool water temperature

As we all know, the human body constantly generates heat due to the physiological effects of metabolism. The generated heat, in addition to meeting the necessary physiological requirements of the human body, must also be sent out to the body continuously through convection, radiation, and evaporation, in order to maintain the balance of human heat. If the ambient temperature is too high, the heat generated by the human body is not easy to dissipate, and the human body will feel very hot. If the ambient temperature is too low, the body will feel too cold if the heat generated by humans is dissipated too quickly. This is true not only in the air but also in water. Because the heat transfer coefficient of the human body for water is larger than the air, the DC inverter swimming pool heat pump for the pool water temperature requirements are higher than the air requirements. To determine the water temperature of the pool first, and then determine the air temperature of the indoor area of the pool.

In a word, the pool area design DC inverter swimming pool heat pump must consider two problems, one is that the relative humidity is too high, which will make the air dew point, and in the winter envelope structure surface degree is low, it is easy to make its condensation, especially the window surface condensation. The other is the impact on the human body. If the relative humidity is too low, it will accelerate the evaporation of water on the skin surface of the people who just come out of the water, and the use of the human body will produce a cold feeling. Therefore, the relative humidity of the indoor air in the pool is generally RH50-70%, and it is not allowed to exceed RH75%. To avoid the occurrence of the above situation.
