Refrigerador de água para ensaios a alta e baixa temperatura de combustível de aviação

Application of water chillers in high and low temperature testing of aviation fuel:

Low temperature requirements:

• Fuel freezing point test: used to test the freezing point of aviation fuel at low temperatures to ensure that the fuel will not freeze under cold conditions.
• Low temperature performance test: evaluate the performance parameters such as fluidity and viscosity of aviation fuel under low temperature conditions to ensure that the fuel can be transported and burned normally at low temperatures. In cold areas, the fuel may need to be cooled between -40°C and -50°C.

High temperature requirements:

• Thermal stability test: evaluate the thermal stability of aviation fuel under high temperature conditions to ensure that the fuel will not decompose or produce harmful substances under high temperature conditions.
• Volatility test: test the volatility of the fuel at high temperatures to ensure that the fuel will not volatilize excessively under high temperature conditions. In high temperature areas, the fuel may need to be cooled between 30°C and 40°C.

Temperature Cycle Test:

•Thermal Cycle Performance Test: Simulates the cyclic changes of aviation fuel under different temperature conditions to evaluate the performance stability of the fuel under temperature change conditions. It is usually necessary to control the temperature within the range of ±1°C to ±0.5°C to ensure the stability and safety of the fuel during transportation and storage.

Temperature Variation Range:

•Aviation fuel may experience large temperature changes in different seasons and regions, so the cooling system needs to be able to adapt to a wide temperature variation range. The water chiller needs to be able to operate over a wide temperature range, usually covering a range from extremely low temperatures (such as -60°C) to higher temperatures (such as above 40°C). The ability to quickly switch between high and low temperatures to simulate the rapid temperature changes of aviation fuel under different temperature conditions is very important for evaluating the thermal cycle performance of the fuel.
