HERMETIC AMMONIA LIQUID COOLERS FOR AIR-CONDITIONING AND COMMERCIAL REFRIGERATION.

[In German. / En allemand.]

Type of article: Article

Summary

A SUMMARY IS GIVEN OF THE VARIOUS ASPECTS OF DEVELOPING THE USE OF AMMONIA IN INSTALLATIONS WITH 10 TO 1,000 KILOWATTS OF CAPACITY. INSTALLATIONS MUST BE DEVELOPED WHICH WILL CONTAIN THE LEAST AMOUNT POSSIBLE OF REFRIGERANT CHARGE (A 400 KILOWATT INSTALLATION, FOR EXAMPLE, WOULD CONTAIN ONLY 35 KG OF AMMONIA). ONE POSSIBILITY WOULD BE TO USE AMMONIA AS ONLY THE REFRIGERANT, WITH THE SECONDARY COOLANT PERHAPS BEING A WATER-GLYCOL MIXTURE FOR TEMPERATURES DOWN TO ABOUT 263 K (-10 DEG C). SUCH INSTALLATIONS WOULD BE EQUIPPED WITH ALL THE NECESSARY SAFETY DEVICES WITHIN AN AIRTIGHT CASING. THE COMPRESSOR WOULD HAVE TO BE EQUIPPED WITH AN AMMONIA-RESISTANT MOTOR. IT IS NOTED THAT AN IMPORTANT FACTOR WILL BE APPLYING THE TECHNOLOGY DEVELOPED IN THE LABORATORY. M. C.
