The amount of condenser subcooling needed is system dependent. The more pressure drops — friction and static — associated with the lines and accessories that carry the liquid in the system, the more need there will be for liquid subcooling to prevent liquid line flash gas.
At 34 inches wide, the PACSlim-12 air-cooled portable air conditioner can roll through a standard doorway. The unit provides 12 tons (144,000 Btuh) of cooling.

Honolulu Seawater Air Conditioning LLC (HSWAC) announced that the Hawaii Community Development Authority (HCDA) approved to enter into a Grant of Non-Exclusive Easement and Construction Right of Entry in Kakaako makai lands for the underground piping of the company’s seawater air conditioning project for Honolulu.
Condenser subcooling ensures that there is a liquid seal at the condenser’s bottom so the liquid line or receiver will not be fed with vapors. This condition prevents any noncondensables, like refrigerant vapor or air, from leaving the condenser’s bottom and entering the receiver or liquid line.
The Consortium for Energy Efficiency (CEE) released its revised “High Efficiency Commercial Air Conditioning and Heat Pump Initiative.” The initiative includes a high-efficiency energy performance specification for commercial air conditioning and heat pump equipment.
Custom Design Heating and Cooling owner Josh Hipke recently awarded 21-year-old college student Matthew Bowen a Coleman 14.5 SEER LX Series MicroChannel air conditioner as a reward for winning the dealer’s Survival of the Coolest contest at the Lincoln County Fair in Merrill, Wis.
Industry veteran Mike Paulson has been brought on as president of the newly-founded and California-based air conditioning company, AmeriCool Inc. Paulson brings with him 10 years of experience at MovinCool, where he served as division manager of both North and South America.
The Flow T1 adapter is a preventive solution to the clogged air conditioning drain line. The adapter is placed in the main drain line of any HVAC air-handler system to prevent the main drain line from becoming clogged.
