COMMERCIAL HVAC EQUIPMENTCommercial HVAC Equipment 2 Condenser Total Heat of Rejection The heat to be rejected by the condenser in condensing the refrigerant is equal to the sum of the refrigeration effect (RE) of the evaporator plus the heat equivalent of the work of the com-pression. RE + Compressor work = THR (Total Heat Rejection) Heat rejection in the condenser
Condenser (heat transfer) - WikipediaAir cooled – If the condenser is located on the outside of the unit, the air cooled condenser can provide the easiest arrangement. These types of condensers eject heat to the outdoors and are simple to install. Most common uses for this condenser are domestic refrigerators, upright freezers and in residential packaged air conditioning units.

HVAC Efficiency Definitions - usair-eng.com22,000( ) 3.414( / ) 220,000 watts x Btuh watt Btuh =2.9 % EQ-2 This means that for every Btuh of electrical energy supplied, 2.9 Btuh of heat can be absorbed. The EER rating evaluates how a unit will perform at one specific point. A higher value for EER represents a higher efficiency at standard conditions.

Calculating Cooling Loads - Engineering ToolBoxCooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor.
