Cold Room Selection Beyond Horsepower, Sizing on Measured Capacity
The Same Nominal 10 HP Can Deliver Sharply Different Cooling Output: Ambient, Evaporating and Condensing Conditions Decide, and Only Laboratory Data Under Specified Conditions Tells the Truth
Most cold room inquiries open with how much horsepower a room needs, and suppliers matching horsepower to room volume issue schemes that bring slow pull-down, wide swings and rooms never reaching the set point. Horsepower is a name for power input rather than capacity unit, so a nominal ten horsepower unit differs in real capacity. Selection depends on target temperature, summer maximum ambient, insulation and sealing, incoming goods temperature, door-opening frequency and respiratory heat loads, all combined into a load calculation. EXTRCOOL publishes laboratory-measured capacity under specified conditions, controls from minus 35 to plus 65 degrees and adjusts output to load. EXTRCOOL provides variable-frequency cold storage solutions."
