1) Air conditioning requirements for hot spring health centers with an area of 132 1㎡ and swimming pools with an area of 722㎡;

2) Indoor swimming pool is required for constant temperature, with an area of 3 12.5 m2, a water depth of 1.6m and a volume of 500m3.

5..2 Air conditioning cold and heat sources

1) The cold and heat source scheme of this project * * * adopts PHNIX air-cooled cold and hot water commercial central air conditioning module PASRW250S-V4 and four triple supply modules PASRW250S-V-QX. 4 sets of PASRW250S-V, with total cooling capacity of 260 KW and total heating capacity of 280 KW；; Four PASRW250S-V-QX sets have a total cooling capacity of 240KW and a total heating capacity of 280KW.

2) The air conditioning area of the hot spring health center is 132 1m2, with a design cooling load of 350kW and a design heating load of132kw;

3) The air conditioning area of the swimming pool is 722m2, and the design cooling load is151kw; The design heat load is 140 KW.

5.3 Air-to-water transfer system

1) The air conditioning water system of the hot spring health pavilion adopts dual control system, which is designed with the same program to ensure the water balance at the end of the air conditioner; The air conditioning water system of natatorium adopts different scheme designs;

2) Horizontal concealed fan coil unit and ceiling should be set at the end of air conditioner;

3) The expansion tank is used to replenish water to the system at constant pressure.

5..3 Air conditioning system

The natatorium uses two new fans PBG040-6 for PHNIX hanging cabinets, with an air volume of 4,000m3, which are respectively arranged at both ends of the natatorium. Fresh air is sent to the swimming pool through the air duct after being treated by the new fan, and discharged from the swimming pool by the exhaust fan. The natural fresh air system is adopted in the hot spring health center.
