Direct expansion systems
Глоссарий терминов по кондиционерам (английский) |
One of two types of basic cooling media (the other is chilled water). direct expansion systems utilize freon for cooling and dehumidification. the three most common methods of heat rejection are air-cooled, water-cooled and glycol cooled.

Dehumidification, английский
- The reduction and removal of water vapor in air by cooling the air below the dew point.
- The reduction of water vapor by cooling the air below the dew point, as well as the removal of water vapor from air by chemical means, refrigeration, etc
- Process of blowing warm, dry air into a full container of cargo to reduce the moisture content of the air and contents in the container and to thereby minimize the possibility of condensation damage.

Merv, английский
- Stands for minimum efficiency reporting value. a measurement of air filter’s ability to remove particles from 3 to 10 microns in size. the merv scale ranges from 1 (least efficient) to 16 (most efficient).

Ton (or tonnage), английский
- Not 2000 lbs, but a unit of measure used to describe the cooling capacity of an air conditioning system. one ton of cooling is based on the amount of heat needed to melt one ton (2000 lbs.) of ice in a 24 hour period (equal to 12,000 btuh).
