WebB. equipping the system with a fixed-bore metering device. C. using a two-speed or variable speed compressor. D. using a lower evaporator saturation temperature. Step-by-step solution Step 1 of 4 In efficiency of the equipment is the measure of how well the equipment performs. WebOct 15, 2024 · Fixed orifice devices are ideal throttling devices if conditions never change. If the load on the system is constant and the ambient temperature remains steady, then a simple capillary tube or piston would be preferable to an adjustable orifice device such as a TXV. However, outside of a laboratory, static conditions are simply not realistic. bearing 7207 bep
