Too great of an external static pressure will result in insuffi cient air that can cause icing of the coil whereas too much air can cause poor humidity control and condensate to be pulled off the evaporator coil causing condensate leakage Too much air can cause motor overloading and in many cases this con stitutes a poorly designed system To determine proper air movement proceed as follows 1 Using a draft gauge inclined manometer measure the static pressure of the return duct at the inlet of the unit Negative Pressure Total External Static 2 Measure the static pressure of the supply duct Positive Pressure 3 Add the two readings together NOTE Both readings may be taken simultaneously and read directly on the manometer as shown in the illustration above if so desired 48 4 Consult proper table for quantity of air If the external static pressure exceeds the minimum or maxi mum allowable statics check for closed dampers dirty filters undersized or poorly laid out ductwork S 201 CHECKING TEMPERATURE RISE Temperature rise is related to the BTUH output of the unit and the amount of air CFM circulated over the indoor coil All units are designed for a given range of temperature increase This is the temperature of the air leaving the unit minus the temperature of the air entering the unit The more air CFM being delivered through a given unit the less the rise will be

The boiling point at atmospheric pressure is 62 9 F A few of the important principles that make the refrigeration cycle possible are heat always flows from a warmer to a cooler body under lower pressure a refrigerant will absorb heat and vaporize at a low temperature the vapors may be drawn off and condensed at a higher pressure and tempera ture to be used again The indoor evaporator coil functions to cool and dehumidify the air conditioned spaces through the evaporative process taking place within the coil tubes NOTE Actual temperatures and pressures are to be obtained from the expanded ratings in the Technical Information Manual High temperature high pressure vapor leaves the compres sor through the discharge line and enters the condenser coil Air drawn through the condenser coil by the condenser fan causes the refrigerant to condense into a liquid by removing heat from the refrigerant As the refrigerant is cooled below its condensing temperature it becomes subcooled The subcooled high pressure liquid refrigerant now leaves the condenser coil via the liquid line until it reaches the indoor expansion device As the refrigerant passes through the expansion device and into the evaporator coil a pressure drop is experienced caus ing the refrigerant to become a low pressure liquid Low pres sure saturated refrigerant enters the evaporator coil where heat is absorbed from the warm air drawn across the coil by the evaporat
