heat, a heat pump can supply heat to a house even on cold winter days. In fact, air at -18 C contains about 85 percent of the heat it contained at 21 C. An air-source heat pump absorbs heat from the outdoor air in winter and rejects heat into outdoor air in summer. It is the most common type of heat pump found in Canadian homes at this time.

The two basic types of heat exchangers are compact and conventional heat exchangers. The ratio of the heat transfer surface area of a heat exchanger to its volume is called the area density β. A heat exchanger with β 700 m2/m3 is classified as a Compact heat exchanger (CHEs) and if β 700 m2/m3 then they are the Conventional heat exchangers.

the phase change is normally 10-1000 times larger than typical heat transfer methods such as heat conduction, forced vapor or liquid convection. Even though a heat pipe has a big potential to remove the thermal energy from a high heat flux source, the heat removal performance of heat pipes cannot be predicted well since a first principles of

The detailed nature of the application dictates whether a heat pipe is used for separating the heat source from the heat sink, temperature control, heat flux transformation, etc. Heat pipes may be classified broadly into thermosyphons and all other heat pipes.

effluent/sea water source heat pumps, 7 vertical loop ground source heat pumps, 4 air source heat pumps, and 2 horizontal ground loop heat pumps. While this is a small percentage of the total number of heat pumps installed around the state, the heat pumps discussed in this report were chosen because their performance and cost data were available.

I. THE HEAT PUMP REFRIGERATION CYCLE The Heat Pump is a refrigeration system like any other refrigeration system in that heat transfers from one place to another. For summer cooling, it can remove heat from occupied areas and transfer the heat to the outside air. When heat is needed, it reverses the action with a reversing valve and will remove .

Heat Transfer: Conduction, Convection and Latent Heat In addition to radiation, energy can also be transferred in the form of heat. There are three ways this can happen: When heat simply diffuses through an object, passing from molecule to molecule, that's called conduction As it turns out, air is actually very poor at diffusing heat

startup behavior of the heat pipe greatly depends on the heat removal at the condenser section and hence condenser is cooled using water calorimeter. Large heat losses were observed between the source and the heat pipe which led to miscalculation of the heat transfer. Adkins et al. (1999) developed sodium heat pipe for solar energy collector. The

2.2 Heat Transfer in Heat Exchanger In a heat exchanger, heat is first transferred from hot fluid to the surface separating the two fluids (boundary) by convection. Next, heat is transferred through the boundary by conduction. Then heat is transferred from the boundary to the cold fluid by convection (Cengel et al., 2008). An ideal
