Heating and ventilation of a sports and recreation center with a swimming pool in Lipetsk

 The estimated temperature of the outside air is -27°C. Relative humidity in the bath halls of the swimming pools is 50-60%, in the halls of preparatory classes -30-60%.

The heat consumption for heating is 150000 kcal/h, including the heat consumption for heating the paths is 15200 kcal/h.

The temperature of the coolant in the heating system is Tp = 95°, To = 70°.  

The water temperature in the heating system of the pool bypass paths is 45/40°C.

The resistance of the pool heating system is 1.7 m E.S.. The resistance of the pool bypass heating system is 0.6 m of inst., the heating registers of the bypass paths made of polypropylene pipes are laid in the concrete floor structure to a depth of 5 cm with a step of 30 cm.

The heating system of the building is two-pipe, dead-end, with piping above the floor. As heating devices, the project provides for cast-iron radiators "MS-140". In the bathrooms, sew up the radiators with decorative grilles. Ball valves are installed on the radiator connections to regulate heat dissipation and dismantle a separate heating device. Drainage of water from the heating systems is provided in the premises of the heating unit. Air removal is carried out with the help of "Maevsky" valves installed at the upper points of the system, in the radiator plugs. The project provides for the heating of the bypass paths of the pool from a heat exchanger installed in the premises of the heating unit. Pipelines of heating systems are made of water and gas pipes according to GOST 3262-75*, electric-welded pipes according to GOST 10704-91* and polypropylene pipes.

The project provides for the installation of air and heat curtains over the doorways of the main entrance of the pool.

The ventilation of the pool is designed to be supply and exhaust with mechanical inducement. Air is supplied to the pool hall, administrative, amenity and technical rooms with the help of modular air intake units of the Korf company with P1-P4 systems. Removal of air from the pool hall from the administrative premises, showers in the attached part is designed by duct fans of the company "Korf". Air is extracted from the technical and household rooms of the pool through ventilation ducts with the help of ducted fans located in the ventilation chamber, equipped with silencers.
