The high and low temperature cycle device integrated machine is a laboratory instrument and equipment produced by Wuxi Guanya with dual functions of rapid cooling and heating.
Its refrigerants are different according to different models.
It drives the heat transfer medium (usually water or oil) from the fuel tank equipped with the built-in heater to the temperature control equipment through the pump, and then returns from the temperature control equipment to the fuel tank
.
The controller adjusts the temperature of the thermal fluid according to the temperature of the thermal fluid measured by the temperature sensor or the internal temperature of the temperature control device, thereby adjusting the temperature of the temperature control device
.
1.
Types of refrigerants of the integrated high and low temperature cycle device: There are many kinds of refrigerants in the integrated high and low temperature cycle device.
According to the composition of the refrigerant, there are single refrigerants and mixed refrigerants; according to the refrigeration of the integrated high and low temperature cycle device The chemical classification of refrigerant substances is mainly divided into three categories: inorganic substances, freons and hydrocarbon mixtures; according to the source of substances, there are natural refrigerants and synthetic refrigerants
.
The nomenclature of refrigerants is represented by the letter "R" and the following numbers and letters are written according to certain rules according to the chemical properties of the refrigerant
.
2: How to choose the refrigerant of the integrated high and low temperature cycle device: The choice of refrigerant is mainly considered from three aspects: whether the refrigeration performance is good, practicality, and whether the substance has an adverse effect on the atmosphere
.
1.
The refrigeration performance of the refrigerant depends on its working requirements, whether it has satisfactory theoretical circulation and thermal performance; 2.
For practical use, the chemical and thermal stability of the refrigerant should be good, and it will not decompose or deteriorate in the refrigeration cycle.
, will not corrode the materials of mechanical equipment, and will not chemically react with lubricating oil
.
3.
Whether the environment is polluted: After the refrigerant is selected according to the properties of the refrigerant, the flow arrangement, structural design and operation of the refrigeration system are required to adapt to it
.
All of these need to be properly handled based on a full grasp of the refrigerant properties
.
