【Summary Description】The concept of thermostats and what they do. Applications of thermostats Its application is very wide, depending on the type of thermostat applied in many products such as home appliances, motors, refrigeration or heating. Working principle of thermostat The working principle is to automatically sample and instantly monitor the ambient temperature through the temperature sensor. When the ambient temperature is higher than the control setpoint the control circuit starts and can set the control return difference. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function is activated. When the controlled temperature can not be effectively controlled, in order to prevent the destruction of the equipment can also stop the equipment to continue to run through the function of tripping. Mainly used in the power sector for a variety of high-voltage switchgear, dry-type transformers, box-type substations and other related areas of temperature use

The concept of thermostats and what they do.
Applications of thermostats
Its application is very wide, depending on the type of thermostat applied in many products such as home appliances, motors, refrigeration or heating.

Working principle of thermostat
The working principle is to automatically sample and instantly monitor the ambient temperature through the temperature sensor.
When the ambient temperature is higher than the control setpoint the control circuit starts and can set the control return difference. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function is activated. When the controlled temperature can not be effectively controlled, in order to prevent the destruction of the equipment can also stop the equipment to continue to run through the function of tripping. Mainly used in the power sector for a variety of high-voltage switchgear, dry-type transformers, box-type substations and other related areas of temperature use

The cold storage market can be basically divided into three markets: high, medium and low end, each of which has its corresponding relative suppliers. 1, the cold storage undertaking volume and technical level are difficult to be reached by other enterprises. Therefore, they occupy a monopoly position in some high-end cold storage market. Cold storage usually contains dozens of storage rooms, each room application 2-4 thermostats ranging. The amount of thermostats used in a cold room may reach more than 100. But now there is also a trend to use no thermostat, using a special controller or PLC developed by a single chip, plus RTD to complete the temperature control. For example, Dalian Iceberg. 2, professional production of refrigeration equipment and the construction of cold storage manufacturers. These manufacturers have certain technical, financial and personnel strength, in a more fixed range, to undertake some projects with relatively low difficulty of the cold storage project. 3, individual combinations, cold storage "guerrillas" and refrigeration equipment dealers around the world. The number of such enterprises, small-scale, to extremely low prices to capture the low-end market, such as a large number of small rural fruit and vegetable cold storage market. Low prices make professional manufacturers can not enter this type of market. The annual output of tens of thousands of. These two types of enterprises in the cold storage is usually only a store room, each store room application 1-2 thermostats, one of the majority of cases.

LCD thermostat three generations of technology development

The first generation of the LCD thermostat is through the triode and resistor step-down voltage to 24 volts later to use, equivalent to build a step-down bridge, when this product to the market for more than a year, less than two years to stop selling, the reason is that with the triode and resistor step-down voltage, the resistor is easy to burn out or triode bad, the failure rate is too high to ensure the service life of the LCD thermostat. However, after the discontinuation of this product, there are still many consumers like the LCD thermostat, because the LCD thermostat is relatively beautiful, intuitive, which evolved the second generation of thermostat technology development period. R & D out of the third generation of LCD thermostat is to take separate technology, we also have a power box, but our power box is installed on top of the fan coil, the panel is installed separately in the eight six line box inside, so as to solve two problems, one is the problem of heat dissipation, the second is to solve the problem of inaccurate induction temperature of the panel affected by heat. There is a greater advantage is that our power supply box has become larger, four times larger than the second generation of domestic LCD thermostat power supply box, so that it has enough space for heat dissipation. In addition, our power supply box has a circuit board inside, the circuit board is divided into two parts, the middle is disconnected, part of the high-voltage part, part of the low-voltage part, to avoid the generation of induction current and induction voltage, to ensure that the power supply box out of the voltage is very stable, so that the current failure rate of all LCD thermostats we this is the lowest, to overcome the heat dissipation problems of the previous two generations of products, breaking through the Domestic thermostat technology bottleneck
