Solar energy to force household create integration household comfortable system

This society was busy to deal with energy crisis (oil, natural gas, coal, electricity, etc non-renewable resources, nearly exhausted), rising energy prices, the more and more serious influence international economic situation and people's normal life, especially for high energy consumption of the new technology and new product application form the huge resistance; The development and utilization of renewable energy air energy, and solar energy (never exhausted) become the focus of global attention, the Chinese government also in support and encourage the development and use of new energy and renewable energy.

Solar energy is a sun internal continuous fusion reaction process release energy, radiation to earth, people through the photoelectric, optothermal, photochemical way to make the transformation of the human services. Its characteristic is exhaustless, once in lifetime usage, no any pollution. That is solar energy is green environmental protection, cheap energy, solar energy in how to realize the effective use of floor heating is especially important in. This paper enumerates the application of the two kinds of solar floor heating system: one kind is solar + hanging furnace double heat source system,power inverter realize heating and domestic hot water function; Another kind is solar + air source heat pump (or heat pump), can be additional auxiliary electric heating equipment of heat source system, realize set heating, central air-conditioning (refrigeration), domestic hot water for the integration of household comfortable system.

Solar + air source heat pump system

The system can realize floor heating and domestic hot water, central air-conditioning (refrigeration) for the integration of household comfortable system.

Is to use solar energy + air source heat pump (or heat pump), can be additional auxiliary electric heating equipment of heat source system. The design of system optimization, high performance, simple structure, the energy efficiency can reach more than 40%, is a worth universality promotion of typical scheme.

Heating and air conditioning (common) water tank, warm water pump, floor heating pipe, solar panels, when heating demand, automatic control electric valve AV3, AV4 open constitute a solar floor heating system. Water pump (P2) for floor heating water circulating pump, will warm water directly into the solar panels for heat exchange. Air source heat pump as a secondary heating heat source, when solar (rizhao) is insufficient, air source heat pump system and heat exchange coil will heat water tank, so that can fully satisfy the floor heating heat source demand.

Solar + hanging furnace system

The system can realize floor heating and domestic hot water two big functions. System USES solar energy, gas hanging boiler two kinds of heat source, through a "flow balance tank" will be two kinds of heat source weaver effectively, make whole system automation control to achieve the operation is simple,grid tie inverter the operation of the energy saving effect of comfort. Already is a very mature application solutions, there have been more similar engineering example.

Solar heat exchange circulating system

Bearing type solar panels, solar cycle pump, double coil in hot water tank of a group of coil to form a closed loop system. Solar cycle pump by temperature control medium inner loop operation, circulation medium for special antifreeze liquid. Due to the antifreeze liquid by temperature is affected and arise antifreeze medium volume, pressure change, should be in line in the installation expansion valve, safety valve, tank.

Solar energy, hanging the boiler double heat source weavers-all principle

Solar cycle system of double coil in hot water tank heating, heat exchange coil, water pump to form a circulation system, which will be sent to the solar energy heat source water flow balance tank. And wall hanging boiler of hot water, the flow balance tank mixed. Flow balance tank are two heat source system of the weaver key components, have heat source mixing and hydraulic, flow equilibrium distribution role. Warm water pump for floor heating circulating pump, can play the role of circulation and pressurized. Such as stop pump operation, will also to floor heating system implementation comfort temperature control. In the heating period, closed electric valve can cut off the floor heating system.

Double coil in hot water tank, but also for domestic hot water of volume type cistern. Hot water the tee mix water valve, but constant is50 ℃of water temperature, and leading pipeline, hot water circulating pump consists of a central hot water system. The system is the most clever design, in the stop heating (closed AV1 electric valve), hanging boiler of hot water by coil heat exchange hot water tank. Therefore H2 heat exchange coil with "two-way heat exchange" action. In the solar inverter energy (rizhao) shortage can also ensure enough living hot water. In the chart the hot water circulating pump (P4) can realize hot water pipe cycle, automatic constant temperature pipeline, the leading water "to open both hot, need not put cold water".
