The integral system

1 first feature representation relations in the system of solar energy and other energy

1.1 solar energy alone system --- no any auxiliary energy solar water heating system;

Before the 1.2 solar energy preheating system -- in the water entering into any other types of heaters, solar hot water system for water preheating;

1.3 solar energy with auxiliary energy system using solar energy and auxiliary energy -joint, and can not rely on solar energy and solar hot water system to provide the requiredheat energy;

2 second feature representation in the heat collector heat transfer fluid whether the user consumption of hot water

2.1 direct system --- a heat transfer fluid (water) was eventually system user consumption or recycle stream to the user water flowing through the collector, also known as single loopsystem or single loop system;

2.2 indirect systems -- heat transfer fluid is not ultimately be the user consumption, orcircular flow to the user of the water without flowing through the collector system for heat transfer fluid but other heat transfer medium, also known as the double circulatory systemor double loop system.

3 third feature representation quality and atmospheric systems transfer working contact situation

3.1 open system - the heat transfer fluid and atmospheric systems have a larger contact area, the contact surface mainly in the open surface heat storage device;

The 3.2 opening system - the heat transfer fluid and atmospheric contact only supply boxand the expansion tank of the free surface or the exhaust pipe opening system;

3.3 closed system - heat transfer fluid completely isolated from the atmosphere.

4 fourth feature representation heat transfer medium in the heat collector condition in

4.1 full system -- in the system in the heat collector is always full of heat transfer fluid;

4.2 return system - as part of the normal working cycle, heat transfer medium in the pumpstops running from the collector into storage device, system and inflow in the pump re open when the collector;

The 4.3 discharge system in order to frost, the water can be discharged from the collectorinstead of using the system.

5 fifth feature indicates the type of system circulation

5.1 natural circulation system only using heat transfer fluid density

Connecting pipe

The hot water from the collector is conveyed to the heat preservation water tank, cold water from the heat preservation water tank will be transported to the collector loopchannel, make the whole system to form a closed. Reasonable design, is connected with the circulating pipeline right of solar system whether can achieve the best work condition is essential. Hot water pipe antifreezing insulation processing must be done. Pipe must havevery high quality, ensure that there are more than 20 years service life.

Control center

The difference of solar hot water system and ordinary solar water heater is the control center. As a system, monitoring, operation, regulation and other functions of the control center is responsible for the entire system, technology is already available through the normal operation of the Internet remote control system.

Solar water heating system control center is composed of computer software and theelectrical box, a circulating pump which.

Heat exchanger

Plate type welded the advantages of detachable plate type heat exchanger efficiency,compact heat exchangers, making up the defect of shell and tube heat exchangerefficiency is low, covers an area of large heat exchanger. Plate shell heat exchanger heat transfer plate wavy oval, circular plate increases heat long, greatly improving the heat transfer performance. Widely used for heat exchange situation, the conditions of high temperature and high pressure.
