      A Heat Loss calculation must be done for each room so that the room heating requirements can be determined. Heat Loss and Heat Gain calculations are needed for sizing unitary heaters, outlets, blowers and ducts. Whole house calculations are necessary for the entire structure in order to properly size the heating and cooling equipment.

      When warm, dry (unsaturated) air is pulled through a water-soaked pad, water is evaporated and is absorbed as water vapor into the air. The air is cooled in the process and the humidity is increased. The evaporator cooling technology is an energy-efficient alternative to compressor-based cooling.
