THE CONTRIBUTION TO THE DESIGN OF HEATING AND HOT WATER SUPPLY SYSTEM BASED ON LOW TEMPERATURE HEAT PUMP SYSTEM IN COMBINATION WITH SOLAR COLLECTORS

摘要

The low-potential sources in combination with solar devices used in supply heating systems present a perspective alternative to fossil energy in both economic and environmental point of view. The issue of low-temperature heating and renewable energy sources is on the present, when humanity stands on the threshold of fuel-energy sources selection, is extraordinary important. Currently the solar energy, geothermal water energy and environmental energy used in supply heating systems with low-energy potential present a perspective alternative in compare to limited fossil energy. The energy utilization appropriateness is depended by geographic area and climate zone. The article present and solve the design issue of low-temperature heat pump system in combination with solar panels devices.
