Thermodynamic Tests
In addition to conducting climatic tests for verifying equipment endurance at specified temperatures, the cooling capacity of HVAC units, heat exchangers, and fans under long-term operation are also tested.
- Measurement of thermal and cooling capacity, energy consumption, airflow, and other parameters.
- The aim of testing is to determine the effectiveness of equipment under long-term operation and its energy consumption.
- Measurement of air characteristics of fans, HVAC units, and cooling units.
Two HVAC test labs are dedicated to measuring thermal and cooling capacity, energy consumption, and airflow as well as various HVAC unit system, heat exchanger, and fan parameters.
The lab allows us to simulate temperature, humidity, and air pressure settings under the equipment’s real operating conditions.
Measurement of characteristics of fans and units – flowrate/pressure (measurement precision of 2%).
Measurement of cooling capacity of units – calculation according to ANSI/ASHRAE Standard 37-2009, (measurement precision of 5%).
An additional two calorimetric chambers are dedicated to testing transportation and stationary refrigeration systems. The aim of this testing is to determine the refrigeration and heating capacity of units on the air side according to precisely specified limit conditions, including extreme temperatures.
Advantages:
- Measurement of torque on compressors.
- Option to measure the cooling capacity on the coolant side.
- Measurement of fuel consumption under standard operating mode.
- Measurement according to ASHRAE 37-2009 and 51-2007.
- Cooling circuit optimization.
