Chiller is a new type of air conditioning equipment which integrates refrigeration and heating. Thechiller is composed of compressor, evaporator and condenser. The cold air from the cold water mechanism is transported to the kitchen or the central air conditioning through the pipe, and then returned to the room through the fan coil for heat exchange; In the summer hot weather, the indoor heat absorption and transfer to the outdoor, so that the indoor stay cool and comfortable; At the same time, the outdoor heat transfer to cool areas or objects, to achieve the purpose of cooling.
The chiller is mainly composed of compressor unit, condenser group and throttling mechanism.
1, the role of the compressor is to convert the mechanical energy of the prime mover into the pressure energy and kinetic energy of the liquid, that is, the reciprocating linear motion of the piston into rotary motion.
Compressor is one of the most important parts in refrigeration system:
It injects energy into the system and converts it into high temperature and high pressure steam to drive the circulating flow of the cooling medium, thus completing the whole process of vapor-liquid conversion.
2. The role of evaporator is to change the low pressure gas from the compressor into the superheated steam at medium pressure and low temperature and output it to the condenser to condense and release heat and depressurize the process.
3. The function of the condenser is to transform the working medium steam at higher temperature from the evaporator into a liquid state with lower pressure and discharge it into the low pressure pipeline for further use.
4. The function of the expansion valve is to control the amount of liquid working medium flowing through the evaporator into the condenser. When the refrigerant flow is too large or too small, it needs to be adjusted to ensure a certain amount of liquid supply to meet the requirements of the system.
5, the purpose of the capillary is to prevent the leakage of steam into the outside air caused by pollution.
6, dryer filter is used to remove moisture in the humid air.
7. The thermal expansion valve is used to restrain the balance of pressure before and after the thermal expansion valve.
8. Electromagnetic four-way reversing switch is used to control the opening and stopping of the oil pump of the refrigerator.
9. Oil storage tank is used to store refrigerant oil.
10, the safety valve plays the role of pressure protection.
11, high and low pressure stop valve respectively cut off and connected with high and low pressure.
12, one-way check valve is also known as check valve.
13. The pressure gauge is used to display the working pressure of the system.
14. Ammeter is used to display the rated current value of the system.
15, temperature control instrument can automatically control the operation of the machine.
16, electric control box to monitor the whole machine.
17, the operation panel has a manual automatic selection switch.
Shanghai Shang Lut refrigeration Equipment Co., Ltd. is engaged in refrigeration equipment research and development, design, production, sales, installation and so on as one of the high-tech enterprises, in the early 21st century, in Fengxian District, Shanghai set up a factory and the introduction of foreign advanced technology, professional design military electrical and freezing, cooling products, After nearly twenty years of development, Shanghai Lut has become an industrial refrigeration, civil air conditioning manufacturing expert, "P, T, C, Q, S" (talent, technology, cost, quality, service) theory and practice of Shanghai Lut in the industry leading position, is also the core competitiveness of the company's development. The refrigeration equipment control system developed by the company is widely used in China and around the world.
At present, Shanghai Shang UE research and development of water cooled screw chiller, water cooled screw cryogenics unit, evaporative chiller, full liquid chiller, air cooled screw chiller, air cooled heat pump unit, air cooled box unit, water cooled box unit products have been widely used in chemical industry, chemical fiber, plastics, grease, food, pharmaceutical, military, printing, painting, electroplating, electronics and other industries to become the process of refrigeration Home, for the rapid development of Chinese industry to provide efficiency and quality assurance.
Shanghai is Lut adhering to the "heart to work, wholehearted service" service concept, adhere to the "people-oriented, scientific environmental protection" business philosophy, constantly develop more suitable for the market, can meet customer needs of refrigeration products, strict and effective pre-sales, after-sales service, adhere to the quality and innovation as the starting point of enterprise behavior, still Lut people will stick to the spirit we have been trying, Lay the groundwork for the cigar to develop into an internationally competitive company.
