Product Introduction
Swimming Pool Dehumidifier System Solutions:
The DUOKAI constant temperature dehumidification unit for swimming pool uses heat pump technology to absorb the energy of the humid air entering the dehumidification unit; transfer it to the pool water to keep the water temperature constant; the humid air that has absorbed energy, the temperature drops, the water vapor condenses into condensed water and is separated from the air, Thus, the absolute humidity of the air is reduced, and the purpose of air dehumidification is achieved. The excess heat absorbed by the unit is transferred to the air heating, to ensure a constant indoor temperature.
DUOKAI swimming pool special constant temperature dehumidification unit relies on electric energy to continuously operate, realizes the dynamic balance of constant temperature, dehumidification and pool water heating with low energy consumption, so as to ensure the maintenance of indoor air temperature and humidity at a lower cost. On this basis, DUOKAI introduces the dual fan system can greatly improve the indoor air quality while ensuring the indoor air temperature and humidity, and reduce the operating cost of the indoor constant temperature swimming pool.
Why dehumidify?
The reason of the moisture problem | Aftermath of the problem |
Strong evaporation of the water surface of the indoor constant temperature swimming pool. Evaporation will cause the indoor air to contain a large amount of chloramine/ trihalomethane (acidic environment) and the evaporation of water will cause 90% of the energy loss. | Impact on the indoor environment The relative humidity is too high, the steel knots of the building are rusted and corroded, the walls are mildewed and fall off; the appearance and life of the building are affected. Condensation is easy to form in winter, condensation on the glass partition wall, and the ground is slippery. |
Effects on the human body It has a stimulating effect on the human body, affects the olfactory response, and is harmful to health, and trihalomethanes can cause cancer; high humidity will make viruses and bacteria easy to breed, and easily lead to respiratory diseases. | |
Impact on pool operation Water evaporation doubles the energy consumption to maintain water temperature, increases operating costs, consumes water, and increases maintenance and operating costs. |
Dehumidification Unit Introduction：
DUOKAI swimming pool constant temperature dehumidification unit is an indoor swimming pool air quality control equipment that integrates refrigeration and temperature control, dehumidification, pool water heating, fresh air, and purification functions.
Working Principle:
Swimming pool dehumidifiers belong to special air treatment equipment, which has the function of maintaining constant indoor temperature and humidity.
It is mainly composed of air supply system, new exhaust system, heating system, refrigeration system and electrical control system.
Air supply system: Fans are used to supply air to make indoor air flow. Generally, there are two types of fans: centrifugal fans and belt-driven fans.
Fresh air exhaust system: While introducing outdoor fresh air, the indoor air is exhausted, so as to conduct fresh air ventilation.
Heating system: Generally, heating methods such as hot water heating and self-contained heat pump heating are used.
Refrigeration and dehumidification system: The refrigeration and dehumidification system is the core part of the unit, mainly composed of compressor, expansion valve, evaporator, refrigerant, condenser and outdoor fan. The refrigerant processed by the compressor turns into a low-temperature liquid and then flows through the evaporator, which will reduce the air temperature. At the same time, the water vapor in the air will become water droplets after being cooled, and the water droplets will follow the evaporator. The fin wall flows down and finally converges in the water receiving tray and finally discharges to the outdoors through the drain pipe. The low-temperature refrigerant will rise in temperature after absorbing the heat in the air and turn into high-temperature steam. The high-temperature steam will remain in the outdoor condenser along the copper tube and then the temperature will drop under the action of the cooling fan, and finally become a vapor-liquid mixture. back to the compressor. This completes the entire refrigeration and dehumidification process.
