Solar energy: solar heating + water + water heating: environmental protection and energy saving heating method Through the engineering practice in recent years, solar energy and low temperature hot water floor radiant heating (referred to as warm water) system integration technology has gradually matured, is recognized as a new heating system, energy saving and environmental protection. In the engineering practice in the current, there are two kinds of such systems are available. One is double heat source solar system + bigualu, the system can carry out heating and provide hot water; the other is a solar and air source heat pump (or pump) system, the system can add the auxiliary electric heating device, can realize heating, central air conditioning (cooling) and hot water integrated operation of solar energy and wall. The furnace system the system can meet the two requirements of floor heating and hot water. The system uses the solar energy, gas boiler two kinds of heat source, through a balancing tank will be two kinds of effective heat source and machine, so that the whole system To achieve automatic control, simple operation, energy saving and comfortable running effect. This is a very mature application program, there are many similar engineering examples. The solar heat exchanger circulation system pressure type solar collector, solar cycle pump, double coil a coil heat water tank (Figure H1) the formation of a closed cycle system. A solar circulating pump (Figure P5) by temperature control in medium cycle operation, circulation medium is special. The antifreeze antifreeze is affected by temperature may lead to changes in the volume of medium pressure and antifreeze, need to install the expansion valve
