3. DVM design process

DVM is a multi-system air conditioner that changes its performance by different conditions such as design

temperature

, indoor and outdoor unit combination rates, heating operation rates, piping length, and

level difference.

It is important to select the appropriate design condition to the load specification of

each room.

• Design temperature

• Calculate cooling and heating loads

• Power supply, piping length and level difference

• Consider design temperature conditions to select

larger indoor types than actual load.

• Determine outdoor units by the sum of the capacity

of preliminary selected indoor units: At this time,

decide how much combination ratio to permit.

•

Calculate actual capacity of

outdoor units considering

design temperature, indoor

and outdoor unit combination

ratio, piping length, level

difference, heating operation

rates, etc.

• Calculate actual capacity of each indoor

unit based on the calculated outdoor

capacity.

• If Indoor units’ actual capacity is lower than the load,

reselect ones with a larger capacity. Depending on

designers’ own discretion.

• If there is no indoor unit with a larger capacity, add

another indoor unit.
