Thermodynamic heat transfer cycles or refrigeration cycles would be the mathematical and conceptual models for refrigeration, air conditioning and heat pumping systems. A heat pump is an energy-efficient mechanical device which enables for the transportation of thermal energy from one location to another in a lower temperature. It also allows the transfer of waste heat from other regions to maintain a constant temperature in a region. The concept of Thermodynamics deals with the equilibrium of a system at its various states, whether the system is being thermally dynamic (changing state because of external changes) or not. It also deals with the relationship between energy and matter, the existence of a virtual field, the total amount of energy in a definite volume, and the total energy in a vacuum. The first step in the thermodynamics of refrigeration cycle is the analysis and design of a physical law called the First Impression Equation or IEE. This is the law which states that the total energy in a fluid will always remain the same at any given temperature regardless of any change in the physical state of the fluid. Another term you would come across is the boiling point of a substance. This refers to the point at which any liquid substance would boil or transform into steam. Once these four components have been identified, they are then combined in what is called the condensing cycle. In the condensing cycle, they are compressed (thus reducing their volume and forcing hot air into the system) and heated (so that the volume and rate of expansion decreases). The end result is that the system's physical properties become those of water. The temperature is thus brought down to that of the water's freezing point. The pressure is then reduced to that of the hot air and the cycle continues like this. The final stage in the refrigeration cycle is known as the convection stage. In this stage, the heat pumps move air through the system. It is during this stage that the heat generated by the heat pumps is transferred into the cool air through the vents. The ventilation system also moves the heated air away from the house. There are three types of cooling systems used in most homes. These are Central Heating System (CHS), Cooling and Air Conditioning (CCA). A qualified CHS professional should be consulted as soon as the refrigeration cycle has been completed to ensure that all parts are working perfectly. This ensures that the entire system is running smoothly. A qualified HVAC technician should check the condition of air vents and ductwork. If they are not functioning properly then it is advisable to bring them up to the standards required. In addition, if ducts and vents are found to be leaking, then they should be repaired. The last stage in the refrigeration cycle is known as the compression stage. During this stage the gas is compressed so that the cool gas flows to the compressor. In general the compressor holds about ten gallons of cool gas. When compressed, the gas expands to about fifteen gallons. The end result of the process is that the cooled gas is released into the ambient air stream.
