Abstract:
1. An apparatus for measuring cooling power of an electrically-powered Microclimate Cooling Unit (MCU) at a point of use of the MCU, comprising: a fluid supply port connected to a fluid conduit; a flow rate controller disposed in the fluid conduit, the flow rate controller including an analog flow meter; a fluid heater that heats fluid in the fluid conduit downstream of the fluid supply port; a first thermocouple that measures supply fluid temperature in the fluid conduit downstream of the fluid supply port and upstream of the fluid heater; a digital flow meter disposed in the fluid conduit; a fluid return port connected to the fluid conduit downstream of the fluid heater; a second thermocouple that measures return fluid temperature in the fluid conduit downstream of the fluid heater and upstream of the fluid return port; a power supply connected to the fluid heater via a relay; at least one cooling fan connected to the power supply; a housing that contains the fluid conduit, the flow rate controller, the first and second thermocouples, the fluid heater, the relay, the digital flow meter, the power supply and the at least one cooling fan, the housing including an exterior, the exterior having mounted thereon a computer that extracts the temperatures measured by the first and the second thermocouples and the flow rates measured by the digital flow meter and computes cooling power in real-time.
