Basic situation of customers:

Jinjiang Swimming Hall has 4 swimming pools (including indoor standard pool, outdoor standard pool, and outdoor children's pool). Among them: one indoor standard pool: 50 meters × 26 meters, average water depth 2.2 meters, outdoor standard pool 50 meters × 25 meters, average water depth 1.3-1.6 meters, children's pool 1 is 12 meters × 5.8 meters, average water depth 0.4 meters , Children's Pool 2 is 12 meters × 13.45 meters, with an average water depth of 0.6 meters.

Issues that need resolving:

The design requires that the temperature of the indoor standard pool water is 28 degrees, the temperature in the pool hall is maintained at 29 degrees all year round, and the relative humidity is not greater than 65%. The indoor standard pool is large. About 340 kg of water evaporates into water vapor for indoor air every hour. If it is not dehumidified, it will seriously affect the comfort of the athletes and spectators. The pool water must be maintained at a constant temperature of 28 degrees and requires equipment of 421KW heating continuously. In addition, the large pool hall also needs air conditioning cold and heat sources to achieve constant temperature. Under the huge energy demand, if the comprehensive utilization of energy is not realized, a lot of energy will be wasted, and the operating costs will be astonishing.

Solution:

Warm's professional technical team has formulated a complete engineering solution according to the project requirements. Multi-functional pool dehumidification heat pump and air source pool constant temperature heat pump are selected for the scheme. The unit can effectively control the humidity, temperature and water temperature in the pool hall, and realize the comprehensive utilization of energy. The total dehumidification capacity of the unit is 340 kg per hour, which meets the humidity requirements. The waste heat generated by dehumidification is energy recovered before being discharged to the atmosphere. The pool water is preferentially heated to maintain the constant temperature. The air sent into the pool hall is heated to achieve a constant temperature in the case of excess heat. At the same time, the unit has a new exhaust function, which can introduce fresh outdoor air timely. The new exhaust system in the spring and autumn can directly exhaust indoor water vapor to achieve dehumidification and save energy. The inside of the unit adopts a titanium tube heat exchanger, which can effectively prevent the corrosion of chloride ions in the intake air.

Customer benefits:

The project has been running for nearly three years, and it is estimated that compared with a system that does not use comprehensive energy utilization, it can save about 500,000 yuan in operating costs per year, and about 7.5 million yuan can be saved in fifteen years of the entire life cycle, the energy saving benefits are considerable. At the same time, the unit's unique air outlet guarantees the overall temperature and humidity balance of the room and realizes a comfortable environment for watching and racing.
