Refrigeration, air conditioning, and heat pumps (RACHP) have an important impact on the final energy uses of many sectors of modern society, such as residential, commercial, industrial, transport, and automotive. Moreover, RACHP also have an important environmental impact due to the working fluids that deplete the stratospheric ozone layer, which are being phased out according to the Montreal Protocol (1989). Last, but not least, high global working potential (GWP), working fluids (directly), and energy consumption (indirectly) are responsible for a non-negligible quota of greenhouse gas (GHG) emissions in the atmosphere, thus impacting climate change.

The 2002 assessment report, produced under the Montreal Protocol on ozone depleting substances, finds that technical progress has been made by the refrigeration, air conditioning and heat pump industry to comply with requirements to phase out CFCs and in several applications, HCFCs as well. However, there is still a significant amount of installed refrigeration equipment still using CFCs and HCFCs, and so service demand remains high and is best minimised by preventive service, containment, retrofit, recovery and recycling.

Inside an air conditioning system is a chemical refrigerant which is a chemical compound that easily changes states from liquid to vapor and back again. A common trade name for refrigerant which you may be familiar with is Freon.In addition to refrigerant, an air conditioning system requires a minimum of four components, the compressor, condenser, metering device, and evaporator.1) The CompressorThe compressor is the heart of the system. Just like your heart pumps blood through your body at a specific flow rate and pressure, the compressor pumps the refrigerant through the air conditioning system at a designed flow rate and pressure.When the refrigerant enters the compressor it is in a vapor state. It enters the compressor because it is literally being sucked into it. That is why the side of the compressor where refrigerant enters is called the suction side or low pressure side. As its’ name suggests the compressor compresses the vapor as it is being pumped through it. When a vapor is compressed both the pressure and temperature of that vapor increases. The vapor leaving the compressor is very hot. You will get burnt if you were to touch the copper refrigerant lines coming off of the compressor. In the above diagram the high pressure vapor refrigerant is represented by red dots.2) The CondenserThe high temperature refrigerant passes into a condenser coil. As the vapor refrigerant travels through the coil, air from a fan passes over the coil to cool the vapor refrigerant. As the vapor cools it condenses and becomes a liquid, this is referred to as a “change of state”. This “change of state” from vapor to liquid is essential. You may be somewhat familiar with a typical home system where the condensing unit sits outside. When operating you can place your hand over this unit and feel the warm air being blown out. Inside this condensing unit high temperature vapor refrigerant is entering into it, as the heat energy in the vapor is removed by blowing air across the condenser coil, the vapor changes to a liquid. You will soon see that the heat being blown from the condensing unit is the heat that used to be in your home. In the above diagram the liquid is represented by solid red.3) The Metering DeviceThe metering device controls the flow of the liquid refrigerant to the next component which is the evaporator. This is a dividing point between the high pressure and low pressure sides of the system. As this high pressure liquid is passing through the metering device and into the evaporator the pressure drops.4) The EvaporatorAfter leaving the metering device the refrigerant immediately enters a coil called the evaporator. This coil or evaporator has a fan blowing across it. As the refrigerant enters the coil at a lower pressure it begins to bubble and boil and “change state” back to a vapor. During this process of changing state, energy in the form of heat is being removed from the air passing over the coil and is being absorbed by the refrigerant. The heat that was in the air is transferred into the refrigerant. Since heat was removed from the air blowing over the evaporator coil, the air leaving the evaporator coil is cold. You see that an air conditioner makes cold air by having the heat that is in the air absorbed into the refrigerant.Now that heat from your computer room, office area etc. is in the refrigerant what do we do with it? The heated refrigerant is sucked into the compressor and pumped back to the condenser coil. Here in the condenser the heat that was earlier absorbed by the refrigerant in the evaporator section from the space we are cooling is released and removed. The process of the refrigerant “changing states” from vapor to liquid (releasing heat through the condenser) and from vapor to liquid (absorbing heat in the evaporator) is how an air conditioner works.

This program is designed to provide students and technicians with a comprehensive overview of the heat pump system, its operation, and principles. Heat Pumps; Operation, Installation, and Service is designed to provide the reader with a comprehensive overview of heat pump systems. The manual covers basic principles of operation, system components, air flow, defrost methods, balance point, auxiliary electric heat, electrical control wiring, refrigerant piping, installation, refrigerant charging, troubleshooting, dual fuel systems, and an introduction to geothermal systems. The intent of the book is to offer students and technicians information to build upon, in order to enhance their knowledge of the air conditioning and heating field, and more specifically, heat pumps. Before installing or servicing a heat pump system, the technician must have proper training and knowledge of air conditioning/refrigeration theory, principles and operation. With today's energy demands and costs soaring, there is a tremendous need for highly efficient equipment. These systems pose new demands for installers and service technicians. New heat pump systems with single, dual, and variable capacity are being sold which requires trained technicians with the ability to install, service, and maintain this equipment.

A comprehensive, yet reader-friendly source of information about modern heat pump technology, as well as the vapor-compression refrigeration system on which it is based, Heat Pumps is the perfect choice for future service technicians. The book begins by introducing the four major components that make up the vapor-compression system: compressor, condenser, metering device, and evaporator. Other system-level components essential to efficient heat pump operation are also addressed, including: cooling towers, pressure controls, safety devices, and thermostats. Subsequent chapters enable readers equipped with a basic understanding of how heat pumps operate to launch directly into detailed examination of the electrical circuits of the vapor-compression refrigeration system as well as the operation of individual system components. In addition to gaining exposure to different heat pump system configurations (including the increasingly popular geothermal system), dedicated troubleshooting chapters provide abundant opportunities to gain practice in applying the seven steps required for successful completion of every service call. Ample pedagogy plus real-life and simplified examples appear throughout the book, maximizing learning and minimizing the frustration often associated with the study of such a highly-technical, complex topic.

Amidst tightening requirements for eliminating CFC's, HCFC's, halons, and HFC's from use in air conditioning and heat pumps, the search began for replacements that are environmentally benign, non-flammable, and similar to the banned refrigerants in system-level behavior. Refrigerant mixtures are increasingly used as working fluids because they demo
