Solar energy is a very wide range of energy in our field of life. Many aspects are also applied to solar energy. So what constitutes a solar energy instrument?

The solar instrument consists of a host, a probe, and a solenoid valve.

1. Host: It can be divided into semi-automatic controller, automatic controller and full intelligent controller.

The semi-automatic controller has two kinds of dry battery power supply and 220V commercial power supply. The structure is simple and the price is cheap. The main function: water temperature level display, water shortage alarm. Need to manually open the valve on the water, manually close the valve off the water so called semi-automatic.

Automatic control device consists of solenoid valve, sensor and main unit. The main functions include semi-automatic controller function, as well as automatic water supply, manual water supply, water shortage, regular water supply, low water pressure water supply and pipe insulation. Function, general instrument and anti-run water function, solar water completely automatic, for different regions, some instruments also have pressurized water, or thawing function with tropical.

The full intelligent controller consists of host, sensor, electric heating and solenoid valve. It not only includes the above functions, but also features intelligent heating, timing heating, intelligent water supply, timed water supply, leakage protection, time display, power outage memory, and some other instruments. Constant water temperature, constant water level function. The smart meter is not only fully automatic in Sheung Shui, but also ensures that the user has sufficient hot water at any time.

The quality of the copper mold used in the host computer is less than 30 micrometers thick, no varistor resistance, and it is easy to be struck by lightning. That is, the square of the wire diameter inside the electric appliance is not enough, and the electric leakage may cause serious consequences. The secondary transformer instrument heats up too much, which is easy to burn and explode. The sub-chip will lead to chaotic programs, poor anti-interference, and easy to crash. With the development of the instrument, a more scientific and intelligent controller has emerged on the market. Three modes can be selected: smart mode, timing mode, and manual mode. The operation is more convenient and the user's selectivity is stronger.

2, probe: According to the material can be divided into stainless steel probe and silicone probe.

The stainless steel probe consists of a stainless steel jacket heat shrink tube and a thermistor. The quality of a probe depends mainly on the quality of the heat-shrinkable tube it uses. Solar water heaters in the annual 5 to 10 months, the water temperature is in the 80 °C ~ 100 °C, heat shrinkable tube tube and glue composition, the glue itself has volatility, the glue in the high temperature volatility and the quality of the tube is the root of stainless steel probe life Once the glue or tube leaks, the thermistor is damaged, the probe is scrapped, and the instrument fails. The best thermistor is one percent accuracy, and its own material determines its life. Silicone sensors are divided into two types: soft silicone and hard silicone sensors. The exterior of the silicone sensor consists of silicone and activated carbon. The quality of silicone sensor depends on the viscosity of silica gel and activated carbon. Sensors with poor adhesion are prone to cracking, causing the probe to transmit signals that are inaccurate or malfunction. The general stainless steel probe is a four-core wire and the silicone probe is divided into a four-core wire and a two-wire wire. The two core wiring is simple; the four core transmission signal is stable. The current market is dominated by four cores.

3, solenoid valve: generally selected by the instrument manufacturers, there is a non-return filter, the coil inside the standard as well.

Market solenoid valve brands are: Xiangjun, Dongda, Mu source. Formal instrument manufacturers will mark their own on the solenoid valve, such as: Xizi - TMC, Hua Yun - HLC and so on. Solenoid valves are generally divided into pressure and non-pressure valves. After the pressure valve is energized, it needs a certain pressure to open. It is generally used in the place with tap water. The pressure of the non-pressure valve (known as the low pressure valve) is very low. It is mainly used in the place where the water tower supplies water (water tower is higher than the solar water tank. The water in the tower flows through the pressureless valve to the tank.)
