Tescor’s Automotive A/C Compressor Calorimeters are designed in accordance with Ashrae Standard 23 and ISO Standard 917. The calorimeters are provided with a secondary refrigerant calorimeter vessel and Micro Motion coriolis mass flow sensor to provide accurate and repeatable determination of compressor capacity.   

Tescor’s calorimeter system provides the customer with control of such parameters as compressor speed, discharge pressure, liquid temperature or sub-cooling, suction temperature or superheat, and suction pressure. In addition, Tescor offers as an option an oil control loop that allows the user to precisely and accurately control and report the percentage of oil in circulation automatically, in real-time.

 Automotive A/C Compressor Calorimeter
 

The calorimeter systems are designed to provide heat balances within ±2% with a repeatability of ±1%. Tescor offers a standard line of automotive compressor calorimeters up to 16.7 ton capacities.
