In such an air conditioning system, the accumulator also prevents the liquid refrigerant from reaching the compressor during low cooling demand periods. The air, often after being filtered by a cabin air filter , is blown by an adjustable speed electric powered centrifugal fan across the evaporator, causing the liquid part of the cold ...
The RAV4's 2.0-litre engine was upgraded with a new 2.4-litre engine in the US and Australia producing 120 kW (160 hp; 160 PS) and 220 N⋅m (162 lb⋅ft). Other countries got mostly 5-door models with the 2.0-litre VVT-i engine. Automatic electric air conditioning also became available.
A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...
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]
The resulting air stratum is a vertical gradient with high-density and cooler air below and low-density and warmer air above. [9] Due to the naturally convective movement of air, stratification is used predominantly in cooling conditions.
