　　2、 Refrigeration system

　　1. System concept: Adopting the industry's temperature balance technology (cooling without heating), energy regulation technology is used to balance temperature control without the need for additional heating during cooling and low-temperature balance. Energy regulation technology, also known as PID control, regulates the flow rate of refrigerant by adjusting the mass of refrigerant entering the evaporator per unit time, in order to control the cooling power and thus control the temperature of the laboratory.

　　2. Compared to the previous "balanced temperature control method" of heating and cooling at the same time, the energy consumption is very high. However, using this technology can greatly reduce the operating costs of customers and extend the life of compressors, which can save users a considerable amount of electricity expenses during the product life cycle (depending on the actual frequency of use by customers)

　　3. Refrigeration hardware: Adopting the "Taikang" fully enclosed compressor.

　　4. Refrigerant: Environmentally friendly refrigerants R404a and R23 are used.

　　5. Refrigeration evaporator: A corrugated fin refrigeration evaporator is used, located in the air duct interlayer at one end of the test chamber, and is forced to ventilate by a blower motor for rapid heat exchange.

　　6. Auxiliary components: Other auxiliary components in the refrigeration system of this test chamber, such as solenoid valves, filters, etc., are also imported by our company; If using Italian CAS solenoid valves, bypass valves, etc., other accessories are also selected from domestic brand refrigeration accessories.

　　7. Low temperature piping: Low temperature piping uses oxygen free copper pipes and nitrogen filled welding (traditional methods use ordinary copper pipes, direct welding methods can easily produce oxides on the inner wall of the copper pipes, causing blockage of the refrigeration system and preventing or slowing down the cooling of the test chamber)

　　There is a condensate drain tray at the bottom of the refrigeration system and it is discharged outside the box.

　　8. Vibration reduction: Adopt compressor rubber pads or spring vibration reduction measures; The refrigeration system pipeline adopts the method of adding R and elbows to avoid the deformation of copper pipes caused by vibration and temperature changes, which may cause the refrigeration system pipeline to rupture.

　　9. Noise reduction: Special wave shaped sound-absorbing sponge is used for sound absorption.
