Engines with higher efficiency have more energy leave as mechanical motion and less as waste heat. Some waste heat is essential: it guides heat through the engine, much as a water wheel works only if there is some exit velocity (energy) in the waste water to carry it away and make room for more water. Thus all heat engines need cooling to operate.
Efforts to prevent flash-gas in the liquid line include a cautious design of the cooling system and its piping, but also the incorporation of gear that might help solve this type of difficulty. The inclusion of a refrigerant receiver is a common, cheap and simple way of decreasing the gas ratio in the liquid line.
U.S. regulators are warning airlines to limit the use of an anti-icing system on Boeing 737 Max jets in dry air to avoid overheating engine-housing parts, which could cause them to break away from ...
A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator.
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]
With the use of ADI, the injected water and alcohol (which is mixed with the water to prevent it from becoming ice) absorbs the excess heat to prevent detonation while still allowing for a leaner and more powerful mixture. [3] Notable engine with water fuel injection: BMW 801, Daimler-Benz DB 605, Junkers Jumo 213, Pratt & Whitney Double Wasp.
A crankcase heater is an electrical component in a compressor in an air-conditioning system, heat pump system, or chiller system. The crankcase heater is normally on all the time, even when the unit is not running, though temperature sensors and set points may turn it off when not needed.
This system mechanically adds power back to the drive-line, utilizing a Rankine engine as the energy conversion method. The WFHRS is designed for a variety of different applications, both fixed and variable RPM, aftermarket and OEM applications, but generally geared toward larger equipment such as large on-highway trucks, diesel generators ...
