An example of 2 + 1 ⁄ 2-D processing, can be 2 + 1 ⁄ 2-D microextrusion, where, thanks to an optimal control of the process, the obtained extrudate, which is generally, but not always a tube, can have: Tapered profile, which means that diameters or characteristic dimensions, varies independently from each other.
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
A heat pump is a device that consumes energy (usually electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle , cooling the cool space and warming the warm space. [ 1 ]
The coefficient of performance of the first type absorption heat pump is greater than 1, generally 1.5 to 2.5. [4] The heat pump is composed of the main components such as generators, condenser, evaporator, absorber and heat exchanger, as well as the suction device, shielding pump (solution pump and refrigerant pump), and other auxiliary parts.
One large use of a military multifuel engine was the LD series used in the US M35 2 + 1 ⁄ 2-ton and M54 5-ton trucks built between 1963 and 1970. A military standard design using M.A.N. technology, it was able to use different fuels without preparation.

The HSPF is related to the non-dimensional Coefficient of Performance (COP) for a heat pump, which measures the ratio of heat delivered to work done by the compressor. The HSPF can be converted to a seasonally-averaged COP assuming a lossless compressor and no heat loss by multiplying by the heat/energy equivalence factor .29307111 watts per BTU.
