Abstract

PURPOSE: A refrigerant sealing liquid slightly soluble in various types of refrigerants, having improved heat resistance, with a slight evaporation loss, usable in open boiling coolers, comprising a specific polyethylene glycol.
CONSTITUTION: A liquid, e.g. tetraethylene or octaethylene glycol, selected from a polyethylene glycol of the formula (n is 3W13) as a sealing medium for a refrigerent is filled above the top of the refrigerant in an open boiling cooler comprising (a) a cooling vessel consisting of an evaporating unit and a condenser, (b) a liquid reservoir with a top opening, (c) a means connecting (b) to (a), and (d) a halogenated hydrocarbon refrigerant filled into (a) and (c). The polyethylene glycol is useful as a refrigerant sealing liquid.
