Heat Pump Systems that Save
Energy and Provide Outstanding
Heating and Cooling All Year
• All-season comfort in any climate
• High energy savings capability
• Suitable for new construction or
replacement
Features/Benefits
System indoor and outdoor
sections offer outstanding
performance in either the
cooling or heating mode
Heat pump system energy
savings opportunity
Electrical energy consumption is
always a prime concern when selecting
an air-conditioning system for a com-
mercial application. An easy, effective
way to save energy is to install a heat
pump. Should your building plans call
for one, consider a matched Carrier
38AQS/40RMQ heat pump system.
These systems not only provide highly
efficient cooling, they also double as a
clean, safe, efficient source of heat. In
fact, they are capable of delivering
approximately 3 units of heat energy
for each unit of electrical power
consumed.
Heat pump uniqueness
The outstanding performance of these
heat pump systems is due to the heat
pump's ability to absorb and transfer
heat — from outdoors to indoors for
heating, and from indoors to outdoors
for cooling. System indoor and out-
door sections operate as evaporators
or condensers, depending on whether
heating or cooling is required. The
heating cycle always starts with the
outdoor coil absorbing heat from the
