38AQS Commercial Air-Cooled Condensing Unit
Features
Carrier's 38AQS Heat Pump Systems are
available in nominal capacities from 7-1/2 to 15-tons cooling
and 83,000 to 164,000 Btu/hr. heating. Designed to match with
Carrier's 40RMQ air handlers, these heat pump systems save energy
with cooling EERs (energy efficiency ratios) as high as 9.8 and
heat pump COPs (coefficient of performance) of 3.0. Utilizing
Carrier's time-proven, highly reliable 06D reciprocating semi-hermetic
compressors, these units are designed for long life. Carrier's
06D compressors are famous throughout the industry for their reliability.
These compressors have vane-type oil pumps with positive oil pressure,
an oil pressure regulating valve, class F stator windings, capacity
reduction, oil level sight glass, and service valves. Through
cylinder unloading, the 38AQS012 and 016 can reduce capacity during
the cooling phase to reduce energy usage and improve space temperature
regulation. A Cycle-LOC device in the 38AQS control box
holds the compressor off-line if any operational or safety device
trips the compressor. The unit can be reset manually at the thermostat.
For that extra measure of heat pump
performance, variable refrigeration circuiting (VRC) provides
improved heat transfer, higher COPs, improved reliability and
faster coil defrosting. The design combines check valves and fixed-bore
refrigerant metering to optimize the circuiting of the outdoor
coil. This circuiting achieves the best performance possible during
both the heating and cooling modes.
The latest safety standards for 38AQS008 units are assured through UL (Underwriters' Laboratories) and CUL (UL Canada) approval.
