Carrier 5H - Manual (Page 32)

A condenser selection that permits operation
of the system at a low condensing temperature,
results
in the lowest compressor motor brake
horsepower and consequently,' the lowest operat­
ing cost. A condenser selection that is heavily
loaded requires the compressor to operate at a
higher condensing temperature, results in higher
compressor motor brake horsepower and operat­
ing cost.
For a given compressor-condenser combina­
tion, the selection of a condensing temperature
may depend on the ratio between power costs and
water costs, on the quantity of water available, on
the
condensing temperature required to achieve
compressor capacity, or possibly the require­
ment to remain within the allowable loading on a
given motor size.
