Applications Tests of Commercial Heat Pump Water Heaters
Abstract
Field application tests have been
conducted on three 4 to 6-ton commercial
heat pump water heater systems in a
restaurant, a coin-operated laundry, and an
office building cafeteria in Atlanta. The
units provide space cooling while rejecting
heat to a water heating load. The tests,
conducted for Georgia Power Company,
examined both quantitative and qualitative
aspects of the heat pumps and the overall
water heating systems. The results provide
valuable insight into the actual operating
characteristics of heat pump water heaters
and useful guidelines for system design and
operation.
The capacity and efficiency of the
units agreed with manufacturers' specifications. COP values ranged from 2 .6 to 3.0
for water heating only, and from 4.1 to 5.0
when space cooling benefit was included. It
was concluded that heat pump water heaters
can provide economical water heating and
space conditioning. However, application
sites must be selected within certain
constraints and a minimum level of operating
control and maintenance must be observed.
