Overview of the cold storage industry and its demand for thermostats

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

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

Julitron advocates low-carbon, energy-saving, green new life

With the development of the world's industrial economy, the dramatic increase in population, the unlimited rise of human desires and uncontrolled production and lifestyle, the world's climate is facing increasingly serious problems, carbon dioxide emissions are increasing, the Earth's ozone layer is suffering from an unprecedented crisis, global catastrophic climate change has repeatedly appeared, has seriously endangered the survival of the human environment and health and safety, even if the human once proud of the high-speed Even the once-proud GDP growth or expansion has been greatly reduced by environmental pollution and climate change. Therefore, Juchuang advocates low-carbon, energy-saving and green new life.

The pillar of the thermostat market is still the mechanical thermostat

The pillar of the thermostat market is still the mechanical thermostat

According to relevant media reports, as China has become a global production base for household appliances, the demand for thermostats in the home appliance industry is growing rapidly. Its market competition is also increasingly fierce, thermostats are generally divided into electronic and mechanical two categories, the application of electronic thermostats has been very popular, but because of the mechanical thermostats have a simple structure, easy to install, long service life, not easy to damage, high reliability, adjustable temperature range, wide range of applications, etc., still huge production and sales.     From the working principle, mechanical thermostats can be divided into pressure type, bimetal type, capillary tube type three categories. Among them, the pressure type is mainly used in refrigeration appliances, such as refrigerators, freezers, air conditioners, etc.; bimetal type can be subdivided into two types of jump and button, mainly for electric kettles, coffee pots, irons and other small appliances and motors, compressors and other home appliances accessories products; and capillary thermostats can also be divided into two types of body up and liquid up, usually supporting the fryer electric oven, microwave oven, dishwasher, electric water heater, etc, Electric water heater and other household appliances with a slightly larger volume of heating. Electronic thermostats are suitable for central air conditioning, single-family heating, floor heating and a variety of oil, gas boilers (wall-hung boilers) and other equipment, is the ideal temperature control products and energy-saving products.     In recent years, driven by the rapid development of China's home appliance industry, the mechanical thermostat market has been maintaining a strong development trend of supply and demand, in a number of national policies to support the promotion of home appliance production and sales to restore vitality, the purchase of thermostats also increased significantly to Market demand for mechanical thermostats is still the pillar of the thermostat market.

The concept of thermostat and its role

The concept of thermostat and its role

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
