BACKGROUND OF THE INVENTION There is a known application in the category of refrigerants for households with a baking powder or narcotic. A low Elm-10 speed, a large capacity, good heat, a small and low cost result in a good performance. Β The connection with this indicated refrigerant is our broadest application. The aforementioned refrigerants have a base of 15 aqueous solutions of calcium or sodium, which are highly portable. A consequence of the collapse is a reduction in the service life of the equipment and a decrease in the operating efficiency of the heat exchanger. 20 In order to increase the efficiency of the cooler, the cooler is equipped with a special appliance to enter the cooler.

Notice that calcium is added to the product or added to various substances, that is, it is 25 times or, as such, is not expressly approved.

The present invention offers the same as the known method for the delivery of a refrigerant to a home which is subject to a complaint of 850 - 3 - on the basis of a primary product of a hydrogen chloride, which is cheaper and more affordable than calcium chloride.

It should be noted that molasses, used in Cache-5 of the supplement, is a cheap available product.

It is recommended that molasses be introduced into the refrigerant in cases from 0.32 to 1.60%. This is sufficient for obtaining the desired effect.

The following is a useful description of the method. 10 Methods include the following investigative procedures. At first, they produce an aqueous solution of a sodium chloride or calcium concentrate from 5 to 30%. Β This product introduced molasses in the amount of 0.32-1.6 sss.%. The mixture is mixed for the production of molasses, after which 15% of the calcium oxide or calcium hydroxide is in the range of 0.03-0.24%. In the case of CaΟ.

The best option for carrying out the invention of the Methods of the receipt of the refrigerant is included in the process, which is based on the consumptions of the calculation of the calcium 28-20 -30 negligence
