Refrigerant formula

Divide the quantity of refrigerant that the heat pump moves by the time it takes to move it. If it pumps 3.6 kilograms of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilograms per second. Divide the answer to step 1 by the answer to step 2: 51.2 / 0.36 = 142.2 kilojoules per kilogram.

What is the chemical formula of r134?

CH2FCF3 1,1,1,2-Tetrafluoroethane / Formula

What chemicals are in refrigerant?

HCFC refers to the chemical composition of the refrigerant. HydroChloroFluoroCarbon indicates that the refrigerant is comprised of Hydrogen, Chlorine, Fluorine, and Carbon. A blend that contains both an HCFC and HFC is considered an HCFC refrigerant.

What is the chemical formula for refrigerant R22?

R22 refrigerant gas is composed of Difluorochloromethane, also known as Monochlorodifluoromethane, freon, abbreviated as HCFC-22, and its chemical formula is CHClF2.

What is capacity of refrigerant?

Refrigeration Capacity means how much of a product can be held within a refrigeration unit. It also refers to the energy required to produce the cooling. These are valuable and important features of refrigeration. As a healthcare facility, this allows you to store more medication vital to your patient's needs.

How much refrigerant is in a 1.5 ton unit?

The rule of thumb is two to four pounds of refrigerant per one ton of your unit.

Why R134a is not used in AC?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn't cool as well as R12. In addition, there was the lubricant issue. Because A/C compressors have moving parts, they require oil.

What is R-32 refrigerant?

R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.

Why R134a is used as refrigerant?

Most refrigerators widely adopt R134a (HFC) refrigerant on the basis of its excellent cooling capacity.

Which refrigerant is used in AC?

What type of refrigerant is used in air conditioning systems? There are many different types of refrigerant used in a variety of refrigeration products, but for air conditioning systems, there are two main types; R-22 or more commonly known as Freon, and R410A, also known as Puron.

What gas is used in refrigerant?

NITROGEN is used as a refrigerant. Nitrogen is a liquid at temperatures below −196. 50C and is used as a refrigerant for such things as preservation of blood and cooling of large computer systems, as well as some industrial uses.

Which gas is used in AC?

R22 with a molecular formula of CHCLF2 is the most widely used refrigerant for the Air-conditioners. It constantly changes its state(Solid, Liquid and gas) at different temperature.

What is the chemical name of R134a?

1,1,1,2-Tetrafluoroethane 1,1,1,2-Tetrafluoroethane / IUPAC ID

What is R 12 and R22?

R12 and R22 are two refrigerating agents for air conditioning units. Image Credit: Comstock/Comstock/Getty Images. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.

What is R12 refrigerant?

Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant.

What are the 3 principle of refrigerant?

The absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation are the main principles of the refrigeration process, or cycle.

What is AC capacity in kW?

The basic rule is to have a minimum 1 to 1.5kW of cooling capacity per 10 sq m of space. For smaller rooms of 20 sq m or less, air conditioners with a cooling capacity of 2 to 2.5kW should be sufficient. For areas that are 40 sq m or larger, we recommend larger capacities from 4kW and above.

What is the 1 ton of refrigeration?

A ton of refrigeration is a rate of heat transfer, not an amount of heat. One ton is equal to the heat absorbed in melting 2,000 pounds (1 ton) of ice at 32°F in 24 hours (1 day). This equates to 12,000 Btu/hr or 12,000 Btuh.

Why is AC called 1.5 ton?

Air conditioning tonnage has nothing to do with weight. A ton, as used in the HVAC field, is a term that describes how much heat the AC unit can remove from a home in one hour. The measurement for heat is the British thermal unit (BTU).

How do you calculate 1 ton of refrigeration?

One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2.204 (pounds per kilogram) divided by 1.8 (°C to °F).
