THE PALACE OF WATER SPORTS (DVVS) YEKATERINBURG.
- The total area of the building is 60,000 sq. m.
- The capacity of the spectator stands is 5,230 seats.
- The total area is 10.5 hectares
The complex includes six sports areas:
- diving pool
- demonstration pool
- training pool
- dry swimming pool
- dry jumping gym
- children's pool
All sports areas are isolated, which makes it possible to hold several events in different disciplines of water sports at the same time, without stopping the training process even during major competitions, as well as providing the necessary individual climate parameters in each of the rooms, depending on the type of competition.
The uniqueness of the engineering solution:
An engineering solution has been developed to ensure the required climatic conditions for maintaining temperature and humidity in all rooms while ensuring the utilization of thermal energy for use in the process of preheating water in the hot water system.
The essence of the solution:
The adopted technological solution provides for the secondary use of heat surpluses removed from the premises of the internal combustion engine in order to maintain a microclimate in the preheating system, etc.
The favorable climate in all rooms of the facility is provided by refrigeration equipment with a total cooling capacity of 2,718 MW and a total heat recovery capacity of 1.82 MW.
The project uses a combined air conditioning system: central supply air units supply air cooled to +18...+20 ° C in the volume of the calculated outdoor air flow. Complete assimilation of heat surpluses is provided by a cooling system with fan closers (fan coils).
The water coming from the air conditioning systems into the coolant with the parameters +7/+12 The °C enters the refrigeration center and through an intermediate heat exchanger with a transmitted heat load of 1,204,000 kcal/ h transfers heat to an external circuit with a coolant of 40% aqueous propylene glycol solution with the parameters +5/+10 °C, which is subsequently supplied to the installed monoblock air-cooled refrigerating machines (chillers). The chillers include additional recuperators installed in series with a condenser for heat recovery using a 40% aqueous propylene glycol solution with coolant parameters. +50/+45 °C.
The coolant coming from the recuperators enters an intermediate heat exchanger installed in the refrigeration center with a transferred heat load of 1,118,000 kcal/h. Water with the following parameters is used as the heat carrier of the heated circuit +48/+43 Further supplied to the ITP (closed circuit) and used for preheating in the 1st stage of the DHW system through an intermediate heat exchanger, with a transmitted heat load of 539,434 kcal/h. The heated side of the heat exchanger receives water from the water pipe in the amount of 17.6 cubic meters. m/h with a temperature of +5C. At the outlet of the DHW heat exchanger of the 1st stage, water comes out with a temperature of +35.6 ° C, which subsequently enters the DHW heat exchanger of the 2nd stage to heat up to a temperature of +65 ° C. After the final heating, the water enters the hot water supply network. The total heat load required to heat tap water from a temperature of +5 °C to +65 °C is 1,054,000 kcal/h.
Thus, the implementation of an engineering solution for the secondary use of recycled heat has reduced the energy consumption for heating water in the hot water system by 539,434 kcal/h.
