FUEL ECONOMY DURING HEAT SUPPLY FOR BUILDINGS WITH INDOOR SWIMMING POOLS UNDER THE CONDITIONS OF JOINT OPERATION OF HEAT PUMP PLANT AND STANDARD HEAT GENERATOR
Abstract
High-performance heat supply for swimming pools is determined by conditions of energy-saving heat consumption within the whole process of maintaining the set temperature of water in the swimming pool and environment in rooms with multi-stage air exchange. The authors have developed the heat pump system to heat the water consumed in the building, which allows both simultaneously and alternately recovering the heat of waste water and air flows of exhaust system of ventilation. The fuel economy during heat supply for buildings with indoor swimming pools under the conditions of joint operation of heat pump plant and standard heat generator was determined for the suggested system on the basis of research results. The dependencies of gas fuel economy on conversion ratio as well as minimal values of conversion ratios on gas fuel cost are determined at different electricity tariffs. Taking into account current ratio of electricity costs and gas fuel costs the economy is about 58–86 % for realistically reachable values of conversion ratios j = 4–6. Bibl. 5, Fig. 3.
