The project was carried out on the basis of the technological task for the design of architectural, construction and technological drawings, - SNiP 410103, SNiP 2080289, manual to SNiP 2080289 - "Basin Design." Methodological recommendations for the design of baths and bath and recreation complexes.

The total heat consumption for heating and ventilation is 0.0163 Gcal/h (0.019 kW), including:

Ventilation

In the rooms of the health center, exhaust ventilation with mechanical motive is designed. The required air exchange is calculated according to the normative multiplicity in the auxiliary rooms and for assimilation of moisture emissions arising during evaporation of water from the open surface of the pools.

General ventilation systems are made mainly on the basis of channel fans from OSTBERG (Sweden) with the emission of exhaust air above the roof through brick channels provided on the roof of the building.

Air intake from the rooms is performed from the upper zone with wiring of main and supply air ducts in the structure of the suspended ceiling. Air intake is carried out mainly through JR5 type louvres from imp Klima (Slovenia) and round exhaust diffusers of the PV1 type.

Exhaust ventilation is designed in each room, the inflow of fresh air in the volume of exhaust total for all communicating rooms is carried out into the hall with the pool. Due to the absence of large thermal and electrical loads, as well as on the basis of the customer's task, the inflow of halls with pools in the room should be supplied periodically in the absence of those engaged naturally through the windows in the external fences due to the discharge in the room created by exhaust systems. For partial heating of incoming cold outside air due to convective heat, heating devices are provided under the windows.

Heating

The heating system is provided from thermal entry into the building of the health center. An input unit with a heat energy metering unit is not provided in this section. Hydraulic and thermal calculation of the heating system was carried out on a temperature plot T11 = 95, T21 = 70 ° С.

The heating system of the health center is designed 2 pipe with 2 dead ends, along the facade horizontal branches.

The hydraulic resistance of the heating system without taking into account the thermal input equipment is - dP=2,3 m.

The volume of the heating system excluding the thermal input equipment is - V = 168 l.

The main pipelines of the heating system are designed in the floor along the external walls.

Steel panel compact radiators from Kermi (Germany) have been adopted as heating devices. Radiator panels are welded from two stamped sheets, made of high-quality cold rolled steel with a thickness of 1.25mm. Fins are made of steel sheet with thickness of 0.5 mm.

To enable automatic maintenance of the specified internal air temperature, an automatic RTDN temperature control valve with a thermostatic head type RTD3640 from Danfoss is installed on each heating device on the supply supply. RLVK type shut-off valves shall be installed at the outlet of the heating device.

To be able to exhaust air from the heating system, a manual air outlet valve of the Mayevsky crane type is installed on each heating device in the upper plug.

In the thermal input, a distribution comb is installed on the 2nd connection - on the 2nd along the facade branches. A manual balancing valve of type MSV 2650 is installed on the return line prior to connection to the distribution comb for mutual hydraulic linkage of the horizontal branches with pre-setting by Danfoss.

Heating and heating system pipelines are accepted from HENCO metal plastic pipes. Piping in construction structures, as well as the intersection of internal walls and partitions, is laid in a protective corrugated pipe "foot."
