How to observe the operating parameters of the औद्योगिक चिल्लर to judge whether the working condition is good?

1. बाष्पीभवन तापमान आणि बाष्पीभवन दाब

कंप्रेसर सक्शन शट-ऑफ वाल्वच्या शेवटी स्थापित केलेल्या दाब गेजद्वारे दर्शविलेल्या बाष्पीभवन दाबाने औद्योगिक चिलर्सचे बाष्पीभवन तापमान प्रतिबिंबित केले जाऊ शकते. बाष्पीभवन तापमान आणि बाष्पीभवन दाब रेफ्रिजरेशन सिस्टमच्या आवश्यकतांनुसार निर्धारित केले जातात. खूप जास्त चिलरच्या कूलिंग गरजा पूर्ण करू शकत नाही आणि खूप कमी कंप्रेसरची कूलिंग क्षमता कमी करेल आणि ऑपरेशन इकॉनॉमी खराब आहे.

2. कंडेन्सिंग तापमान आणि कंडेनसिंग प्रेशर

The condensation temperature of the refrigerant in the industrial chiller can be based on the reading of the pressure gauge on the condenser. The determination of the condensing temperature is related to the temperature and flow rate of the coolant and the form of the condenser. In general, the condensation temperature of industrial chillers is 3-5°C higher than the cooling water outlet temperature, and 10-15°C higher than the forced cooling air inlet temperature.

3. कंप्रेसरचे सक्शन तापमान

The suction temperature of the compressor refers to the refrigerant temperature read from the thermometer in front of the suction shut-off valve of the compressor. In order to ensure the safe operation of the heart-compressor of the industrial chiller and prevent the occurrence of liquid hammer, the suction temperature should be higher than the evaporation temperature. In Freon refrigeration industrial chillers with regenerators, it is appropriate to maintain a suction temperature of 15°C. For ammonia refrigeration industrial chillers, the suction superheat is generally about 10°C.

4. कंप्रेसरचे डिस्चार्ज तापमान

The compressor discharge temperature of the industrial chiller can be read from the thermometer on the discharge pipe. It is related to the adiabatic index, compression ratio and suction temperature of the refrigerant. The higher the suction temperature and the higher the compression ratio, the higher the exhaust temperature, and vice versa.

The liquid subcooling before throttling can have a high cooling effect. The subcooling temperature can be measured from the thermometer on the liquid pipe in front of the throttle valve. Under normal circumstances, it is 1.5-3℃ higher than the outlet temperature of the subcooler cooling water.
