комбинированная система ОВИК (Like a hybrid car, a hybrid HVAC system can "choose" between two different energy sources to attain the highest efficiency. Depending on the demand for power, a hybrid vehicle decides to run on battery power or power from a gasoline engine. With hybrid HVAC, the system's computer selects either an electrically-powered heat pump or a furnace that burns natural gas, propane or fuel oil. What does this mean for you as a homeowner? Cheaper energy bills and more effective comfort in the winter and summer! Alexander Demidov) |
