Hybrid heating system and control method fused with heat pump system and solar light by solar and air heat

摘要

The present invention introduces a solar thermal system that does not boil over or freeze, and uses hot water stored by boiling water stored in a heat storage tank for direct heating and hot water. Since the performance of the heat pump decreases when the temperature drops below zero, the solar heat utilization technology that can use the hot water from the heat storage tank that has fallen below the solar heat exclusive heating temperature as the evaporative heat source of the heat pump, and in the heat pump system, air heat evaporator and heat storage tank hot water With a thermal evaporator, the performance of the heat pump can be improved with a control technology that can be selectively utilized by adjusting the set value of the outside air temperature in the indoor temperature controller from the air heat evaporator to the hot water heat evaporator according to the outside temperature. In addition, it features a method of selectively controlling a solar heat-only heating mode and a heat pump heating mode by detecting the heat storage temperature of the heat storage tank, and a hot water heat supply method and control technology capable of maintaining a constant evaporation temperature of the hot water heat evaporator. Hybrid heat pump A composite new that all or part of the power consumption used in the heating system is covered by solar power generation. As a renewable energy use technology, hybrid heat pump cooling using solar heat, air heat, and sunlight that can implement a zero-energy house system. It relates to a heating system and a control method.
