🔍 Key Concepts

• Refrigeration cycle basics – what happens to heat at the evaporator and condenser • Effect of frost/ice on heat transfer – does frost make coils more or less efficient? • Defrost procedures – what is standard practice for defrosting evaporator coils in multi-box systems

💭 Think About

• Think about how a layer of frost on the evaporator affects air flow and heat transfer between the box air and the refrigerant inside the coils. • Consider why hot gas or electric heaters might be used in defrost, and what role the evaporator fan should or should not play during defrost. • Ask yourself: if you simply stop the compressor, what will happen to the frost already on the coils?

✅ Before You Answer

• Verify whether frost is an insulator or a conductor of heat in this context. • Check standard defrost methods: is hot gas / electric defrost normally done with fans running or stopped? • Confirm whether stopping the compressor alone actually provides a source of heat to melt the ice, or just stops further cooling.
