Temperature water controller principle
Room temperature controller according to the temperature changes in the working environment, the physical deformation occurs within the switch to produce certain special effects, resulting in a series of automatic control elements, or electronic components at different temperatures, the working state of the different principles of the temperature data to the circuit to provide the temperature data to the power supply circuit to collect temperature data. Ordinary thermostat is through the ground temperature sensing package to control the pressure, the temperature is low, low pressure, when the pressure is lower than a certain value, the thermostat contacts will be disconnected, the compressor stops working. It is the principle of pressure action to promote the contact of the on and off.
Plumbing thermostat
Mechanical thermostat: the use of sensitive gas cartridges or heat-sensitive bimetal for the temperature-sensitive element, constituting a mechanical contact temperature control switch. This type of thermostat in Europe and the United States market more, only a small part of the domestic manufacturers to promote such products. Mechanical floor heating thermostat usually contact current is not greater than 8A, suitable for water heating system control valve open and close. Its advantages lie in low cost, simple installation and use, long-term reliability; disadvantages for the temperature control switch deviation (generally greater than ± 3 ℃), the display is not intuitive enough, a single function; and the output contact current is only 8A, but also limits its application in the electric heating project.
Electronic thermostat: according to the contact current size to distinguish between the electronic thermostat continuation of all the advantages of the mechanical thermostat, in terms of functionality greatly improved the mechanical thermostat shortcomings, the degree of intelligent control to meet the basic application of all occasions. Therefore, it is very widely used in our country, especially suitable for children and aging people. Because of the simple operation, long-term reliability is good, but also a lot of rational "minimalist" young families especially favored.
LCD thermostat: LCD thermostat fully embodies the control system of intelligent, automated, personalized consumer concept. Popularity in our country is much higher than in Europe and the United States, so in our country in a variety of forms, varieties, quality is uneven.
