Capillary Type Thermostat

Capillary Type Thermostat is a device for temperature regulation and control based on the capillary principle. The following is a detailed introduction to the Capillary Type Thermostat:

1.Working principle

Basic structure: Capillary Type Thermostat is mainly composed of temperature sensing bulb (Bulb), capillary tube (Capillary) and control mechanism. The temperature sensing bag is filled with temperature sensing fluid, which can change its volume as the ambient temperature changes.

Temperature sensing: When the ambient temperature changes, the volume of the temperature-sensing fluid in the temperature-sensing bag will change accordingly, resulting in pressure changes.

Signal transmission: The generated pressure changes are transmitted to the control mechanism through the capillary tube. A capillary is a tube with a small inner diameter and a relatively long length that is capable of transmitting small pressure changes.

Control action: The control mechanism controls the operation of the heating or refrigeration equipment according to the received pressure signal, thereby adjusting the ambient temperature to the set value.

2.Structural features

Temperature sensing bag: Usually a small metal or plastic container filled with temperature-sensing fluid that can sensitively sense changes in ambient temperature.

Capillary tube: connects the temperature sensing bag and the control mechanism, and is responsible for transmitting the pressure changes in the temperature sensing bag. The inner diameter of the capillary tube is usually between 0.62.5mm and the length between 0.35m, which can be customized according to specific application scenarios and needs.

Control mechanism: Controls the operation of heating or cooling equipment based on the received pressure signal. The control mechanism usually includes components such as switches and regulating devices to achieve precise temperature control.

3.Performance parameters

Temperature range: The temperature range of the Capillary Type Thermostat varies depending on the specific model and application scenario, and is generally able to meet most temperature control needs.

Control accuracy: Due to the use of capillary principle for temperature sensing and adjustment, the Capillary Type Thermostat has high control accuracy and can meet application scenarios that require high temperature control accuracy.

Response time: Capillary Type Thermostat has a fast response time and can quickly sense changes in ambient temperature and make corresponding control actions.

4.Application scenarios

Refrigeration system: In refrigeration systems, Capillary Type Thermostat is usually used as a throttling mechanism, connected between the condenser outlet and the evaporator inlet, to control the flow and pressure of the refrigerant to achieve efficient operation of the refrigeration system.

Small commercial refrigeration devices: such as small cold water dispensers, small ice cream machines, etc., usually use Capillary Type Thermostat instead of thermal expansion valve as the throttling mechanism to achieve precise temperature control.

Laboratory equipment: In laboratory equipment, Capillary Type Thermostat is also commonly used for temperature control, such as incubators, incubators, etc.

5.Advantage

Simple structure: The Capillary Type Thermostat adopts a mechanical control method with a relatively simple structure and is easy to install and maintain.

High reliability: Due to the mechanical control method, complex electronic components and circuits are not required, so it has high reliability.

High control accuracy: The capillary principle is used for temperature sensing and adjustment, with high control accuracy.

Fast response speed: able to quickly sense changes in ambient temperature and make corresponding control actions.

To sum up, the Capillary Type Thermostat is a device for temperature regulation and control based on the capillary principle. It has the advantages of simple structure, high reliability, high control accuracy and fast response speed. It is widely used in refrigeration systems and small commercial refrigeration devices. and laboratory equipment.
