In a refrigerating machine heat rejected is
WebWhen operating a refrigeration machine condenser using r-22 refrigerant, under normal conditions the operator observes that the cooling water is being supplied at 85 degrees f and leaving at 95 degrees f. ... the heat that is removed from the building is finally rejected as. Heat of evaporation of the cooling tower. WebThis will reverse the direction of heat and work interactions, therefore producing a refrigeration cycle. The cycle consists of 1-2: Isothermal heat transfer from cold medium to refrigerant (Evaporator) 2-3: Isentropic (Reversible adiabatic) compression 3-4: Isothermal heat rejection (condenser) 4-1: Isentropic Expansion

Just multiply the hour's watt-hours you measured by 3.413 and you'll have BTUs. Note: your measurements may not be typical. Refrigerator rarely runs when it stays shut with cold food in it.
WebA Direct Water-Cooled System with Cooling Tower is an effective cooling system for industrial applications. It uses a closed-loop system to transfer the heat generated by the machinery to the cooling tower. The water is then cooled by the heat exchange process, and returned to the machinery for reuse. This system is known for its energy ... Webreplacing the turbine by a throttle valve. by implication; isothermal processes are replaced by constant pressure processes.
