Refrigeration

Refrigeration is all substance below a boiling point, capable of absorbing large amounts of heat caused by a change of state.

In the mechanics of refrigeration liquids and gasses are used that have the property to be easily converted from a liquid state to a gas state and viceversa.

Typically in refrigeration, ammonia has been used, but is highly toxic.

Of such gases the most commonly used are the Klea denominations, most importantly are:
134A, 407A, 407B, 407C, and 410.

They have the following characteristics:

Stable chemistry before distinct pressures and temperatures.

Incombustible.

Non-toxic.

No tóxicos.

Leakages are easily detected.

The compressor lubricants are harm-free.

Temperatures with elevated vaporization.

Leakages are easily detected.
