Packaged Terminal Heat Pumps (PTHP)


Program Scope

The certification program includes packaged terminal heat pumps as defined below.

A packaged terminal heat pump consists of a separate, un-encased refrigeration system installed in a cabinet of similar function and configuration to that of a packaged terminal air-conditioner. It utilizes reverse cycle refrigeration as its prime heat source and should have available other supplementary heating by hot water, steam, or electric resistance.

This program applies to 50 and 60 Hz Production Models of New Construction PTHP. A new construction unit is a unit with sleeve dimensions of at least 16 in. high and/or at least 42 in. wide, as defined by ASHRAE Standard 90.1.
