Refrigeration teaching laboratory equipment, vapor compression refrigeration cycle visualization

Refrigeration teaching laboratory equipment, vapor compression refrigeration cycle visual test devices main features: The device is the use of environment-friendly, low-pressure, non-toxic organic solvents SES36 as a refrigerant; through the transparent glass container intuitive and safe, it was observed during the experiment evaporation and condensation processes and phenomena. System control responsive, fast response, high test efficiency, good visual effects. Experimental features: 1, can demonstrate the whole process of vapor compression refrigeration cycle, and the cycle is the most important - "evaporate" and "condensation" process to visualize the forms. Allow students a better understanding of high-temperature high-pressure condensation, low temperature and pressure evaporated. 2, the device can be demonstrated and studied in the pressure in the evaporator and condenser and the refrigerant temperature relationship. 3, demonstrate a variety of experimental process, such as: a refrigerant pumped into the condenser; condenser exhaust; refrigeration system air role and influence. 4. Study evaporation and condensation of the refrigerant temperature on the equipment and the condenser cooling efficiency of heat emission. 5. Effect of pressure ratio compressor refrigeration system performance. 6, it can determine the total heat transfer coefficient of shell and tube heat exchanger. 7, draw out the refrigerant pressure-enthalpy diagram (but you need to install R634A). 8, the measurement driven vapor compression refrigeration cycle required electric power (required to install R634B).
