List at least five factors that must be controlled if a comfortable indoor environment is to be maintained. - Answer-The factors that must be controlled include temperature, humidity, air motion, dust, bacteria, odors, toxic gases, and ionization. ((Ref: 1/1)) Describe in simple terms the basic process by which a refrigerant transfers heat energy. - Answer-A refrigerant is used to transfer heat when it changes states. When liquid refrigerant evaporates into a vapor, heat is absorbed by the...
