Contact the refrigerant producer to confirm the refrigerant authenticity. As shown in Figure 9-36, place the refrigerant in an indoor place with constant temperature and humidity for 24 hours. Then, use a thermometer to measure the temperature of the refrigerant tank outer s...
REMOVE charge to DECREASE liquid line subcooling Note: When adding or removing refrigerant with a TXV equipped system, suction pressure may remain relatively constant. Suction pressure is a function of the evaporator load, and the TXV only controls the evaporator superheat. Low evaporator pressure ma...
PROBLEM TO BE SOLVED: To reduce GWP: Global Warning Potential, increase cooling / heating efficiency, reduce power consumption, and improve COP in an air conditioner using a refrigerant R410A. SOLUTION: A working fluid in which a refrigerant R410A is recovered, is composed of Difluoromethane ...

Off-peak cooling systems use electricity to freeze water in special insulated tanks that contain refrigerant-filled coils. These coils circulate ethylene or propylene glycol and a water mixture that's super chilled to well below freezing. Once the water freezes, at night when energy demand is low...
If I decide to install it myself, will I need vacuums to charge up the lines. I assume that the lines need to be charged up with refrigerant and that it has to be setup by a qualified air conditioning technician correct? YES. YOU WILL NEED A SET OF GAUGES FOR R410A AND A VACUUM...
You can usually find a local supplier that sells to the public, but as a bonus with the EPA cert, you can get licensed by your state to work as a refrigerant contractor. I was a service tech for years and the amount of people that just dumped that stuff into the air is horrifying....
