Charging Jacket Overview
HVACR technicians typically cannot charge a cooling system with cold
outside weather. An outside temperature that is too low makes for a low
load condition at the condenser that is outside the design parameters for the
system.
This is more effective than blocking the incoming air with plastic or
cardboard because it does not restrict airflow around the compressor and
from our studies in the field, it maintains a safe acceptable compressor
temperature.
The charging jacket can only be used on TXV systems because for fixed
restrictor systems, outdoor heat load (dry bulb temperature) is a determining
factor for the amount of superheat to charge to.
For more details relating to installation and use of the Charging Jacket,
consult the operator's manual and any other literature included with the
Charging Jacket.
The charging jacket decreases the efficiency of the heat transfer from the
condenser to the outside environment. This effectively increases the load on
the condenser coil to bring it within designed operating conditions.

The HG3 guides you through
a cold weather subcooling
charge by having you enter pipe
pressures and temperatures and
what that means in regard to the
refrigerant level.
