The document discusses heat pumps. It defines a heat pump as a device that transfers heat from a low-temperature medium to a high-temperature one. Heat pumps operate on the same cycle as refrigerators but differ in their objective, which for heat pumps is to maintain a heated space at a high temperature by absorbing heat from a low-temperature source. The document then describes the key parts of a heat pump - the evaporator, compressor, condenser, and expansion valve - and explains their functions. It discusses the efficiency of heat pumps and provides examples of applications such as air conditioning, drying processes, washing processes, and pasteurization.

Heat Pumps Device that transfers heat from a low- temperature medium to a High-temperature one is the heat pump, shown schematically. Refrigerators and heat pumps operate on the same cycle but differ in their objectives.
The objective of a heat pump, however, is to maintain a Heated space at a high temperature. This is accomplished by absorbing heat From a low-temperature source, such as well or cold outside air in Winter, and supplying this heat to the high- temperature medium such as a House
- Evaporator: Absorbs heat from the environment by obtaining steam. - Compressor: It absorbs the low pressure refrigerant coming from the evaporator, compressing it and giving it at high pressure. - Condenser: Absorbs compressor fluid. - Expansion valve. It expands the liquid, cools it and converts it into gas by expanding it Parts of heat pump

Funtion:
Function: 1-2 Adiabatic Compression. 2-3 Isothermal Compression. 3-4 Adiabatic Expansion. 4-1 Isothermal Expansion.
Efficiency The efficiency increase when the temperature desired in the focus hot id high or when the thermal jump is small. 駒 = 1 1 1 = 1 1 2 = 1 =
The air-to-air heat pump Currently the equipment pump air-air heat are the compact type (package) or split (split). Their capacities oscillate between the 4,500 and 20,000 frig / h. The heat pump of this type fulfills the double function of heating and cooling. Consequently with a single equipment can be achieved the conditions of comfort throughout the year. No chimneys or air intakes are required for the unit to operate. Therefore installation costs are reduced.
Air-Water Heat Pump It extracts the heat from the outside air and transfers it to the premises through a circuit of water at low temperature.
Water-Water Heat Pump Water-water heat pumps use surface water from rivers, lakes, etc. as a heat source. Or groundwater. The temperature of these sources is practically constant throughout the heating season, allowing a constant and high COP throughout the season.
Aplicattions Air conditioning
Drying processes Drying is an important industrial process. Various temperature levels and drying principles are applied in industrial dryers. The most common dryer type is one in which air is heated with steam, gas or hot water and then circulated over the wet product. Thus, the use of a heat pump serves two purposes - heat the dryer and dehumidify and recirculate air.
Washing processes In industry a lot of washing processes occur. Mostly this are processes where hot water, sometimes mixed with a solvent, is prayed over a product. A conventional washing machine is visualized in the figure below.
Pasteurization For pasteurization a product needs to be heated above 70 属C. Afterwards the product is cooled down. In most pasteurization processes heat exchange between the cold and hot product flow is already implemented. The figure below shows an example of a well-known pasteurization process. In this case, milk will be pasteurized. Through pasteurization, organisms are killed which results in a longer durability of the milk.
