|The OTS laboratory includes three temperature and humidity-controlled wind tunnels for the purposes of testing air-to-refrigerant heat exchangers. Testing can be provided to confirm performance data and/or to validate heat exchanger modeling assumptions using CoilDesigner® or other software. Testing can be done with hot water, chilled water, glycol or refrigerant. Testing capabilities are summarized in the following table:|
|Face area||1.5' x 1.5'||3' x 3'|
|Air flow rate||CFM||300||4,000|
|Air inlet temperature||℉||54||122|
|Water flow rate||GPM||n/a||40|
|Water inlet temperature||℉||50||149|
|Water test capacity||kW||n/a||52|
|Refrigerant test capacity - evaporation||kW||n/a||26|
|Refrigerant test capacity - condensation||kW||n/a||27|
|Refrigerant flow rate||lbm/min||n/a||20.5|
OTS uses high accuracy equipment to provide an energy balance within 2% - 5%. Accommodations for other fluids, such as oil, and/or test conditions outside of the range listed above can be made on a case-by-case basis.
