Adding a sunroom to a home can mean extra living space or simply a three-season room that becomes a great deal more hospitable than the average porch or deck. For this discussion we will consider the costs and requirements of adding a 200 square foot (roughly 14'x14') sunroom suitable for year-round usage. According to Hanley Wood and their Remodeling magazine the average sunroom addition in which a slab is poured, post and beam construction is used, and a four-season space is created will cost $72,000.
A refrigerator's defrost cycle works by turning on a heating element that's integrated into the evaporator coil in the appliance's freezer. The heating element warms the evaporator coil and melts any ice that has accumulated on the coil. refrigerator's defrost cycle works by turning on a heating element that's integrated into the evaporator coil in the appliance's freezer.

A heat pump unit will defrost regularly when frost conditions occur. The defrost cycle should be long enough to melt the ice, and short enough to be energy-efficient. In the defrost cycle, the heat pump is automatically operated in reverse, for a moment, in the cooling cycle. This action temporarily warms up the outdoor coil and melts the frost from the coil.
