Figure 1 depicts a typical single stage vapor compression system.

404a refrigerant pressures. The type of refrigerant in refrigeration systems having a refrigerant circuit containing more than 220 pounds 99 8 kg of group a1 or 30 pounds 13 6 kg of any other group refrigerant shall not be changed without prior notification to the code official and compliance with the applicable code provisions for the new refrigerant type. Vapor compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Refrigerant pressure temperature charts for r 22 r 410a.

Along with r 134a there were many other hfc refrigerants that began to take root. Obviously there is a large difference here. 404a was used for supermarket freezers ice machines vending machines and refrigerated transport.

Refrigerant charge quantity for air conditioners heat pumps. Small de minimis releases while making a good faith effort to recover refrigerant. Carbon dioxide has a gwp of one.

Fmi 2010 energy store development conference hfc component comparison 1 relative to r 22 standard cycle 105 f condenser 25 f evaporator 10 f of superheat subcooling 2 from the ipcc ar4 3 l sub classification under public review cond. Pressures 1 v. The higher the number the more damage the refrigerant causes to the world.

Which of the following is required when attaching a gauge set to check system pressures. Venting refrigerant from a recovery machine or recovery cylinder. Recover 80 of the refrigerant with an inoperative compressor and 90 of the refrigerant with an operative compressor.

Capacity 1 cop 1 mass flow rate 1 discharge temps f 1 gwp 100 year 2. Refrigerant pressure temperature chart use the open or close icons to see the descriptions below with the icons. Some of these were r 404a and r 410a.

Release a small amount of refrigerant to check for contamination. In these instances you would either see a mixture of r 134a and r 404a or a straight r 404a system. High side will generally be in a ballpark of 250 280 roughly but that what is the normal suction and discharge pressure of a freon r22 compressor.

Releasing refrigerant while connecting or removing low loss service hoses. As a zero based scale for this measurement our old friend r 744 was used. Pressure values are displayed for r 22 r 410a r 407c r 134a and r 404a refrigerants.

All such systems have four components. Search engine and look up pressure temperature chart for r 22 on it you can look up. In comparison r 404a has a gwp of three thousand nine hundred and twenty two.
