INTRODUCTION

On refrigerated ships (reefers), besides R22, the main refrigerants used are R410A, R407C and R404A. In 1993, five refrigerated ships using ammonia were built.

Since then, ammonia has no longer been used, except on fishing boats.

Indirect systems using brines such as calcium chloride, and plate exchangers, are the most commonly used.

the R-407C is a blend refrigerant of HFC32, HFC-125 and HFC-134a.

It is a long life substitute of R22, harmless to OzoneIt is used in various of air conditioner, and non-

centrifugal refrigeration system. Retrofit of existing R-22 systems. However, 407C

should not be used as a direct, "drop-in" replacement. Also, you should not use 407C in equipment that uses a

flooded evaporator because of the zeotropic behaviour within the system.

INFORMATION

TOXICOLOGICAL INFORMATION

IMMEDIATE (ACUTE) EFFECTS: HFC-32: LC50: 4 hr. (rat) - 520,000 ppm / Cardiac

Sensitization threshold (dog) 350,000 ppm HFC-125: LC50: 4 hr. (rat) - > 800,000 ppm / Cardiac

Sensitization threshold (dog) 75,000 ppm HFC-134a: LC50: 4 hr. (rat) - > 500,000 ppm / Cardiac

Sensitization threshold (dog) > 80,000 ppm

POTENTIAL HEALTH HAZARDS

SKIN: Irritation would result from a defeating action on tissue.

EYES: Liquid contact can cause severe irritation and frostbite.

INHALATION: R-407C is low in acute toxicity in animals.

INGESTION: Ingestion is unlikely because of the low boiling point of the material

DELAYED EFFECTS: None known.

Application

Positive displacement equipment: new or existing residential and commercial air-

conditioners new or existing residential and commercial heat pumps conditioning applications. They include:

New residential and other unitary air conditioning, non-flooded evaporator chillers. With few modifications, 407C can be used in the same equipment designed for use with R-22

Suva® 407C Refrigerant

We will see now some a company cat logic which manufacture this type of refrigerants nowadays and have some real information about its properties, charts, curves and tables.

We will take the Suva® 407C Refrigerant:
