Which one of the following is a HCFC refrigerant example?
HCFCs have less chlorine than CFCs which results in a lower ODP (see section 5.3). Examples of hydrochlorofluorocarbons include R22, R123 and R124 (see Figure 5.3).

What are the effects of moisture in a refrigeration system?
Moisture is water of any kind (solid, liquid, or gas). Moisture can be introduced to the system and combine with the refrigerant to create an acidic solution that can cause damage to internal compressor components.
How do you calculate BTU output?
Multiply the BTUs generated per hour by the time the device is used to calculate its total output. To continue the example, if the device runs for 4 hours, it will generate 375. 04 BTUs in that period of time (93. 76 BTU/hour times 4 hours).
