My invention relates to refrigerating equipcombined therewith in a unit. the side plate o! ment and has reference more particularly to the unit` being removed; facilities for collecting and disposing of moisture Fig. 2 is an enlarged, fragmentary, transverse, that accumulates on the surfaces of the cooling sectional view taken on the line 2-2 of Fig. 1; 5. unit. y Fig. 3 is a longitudinal sectional view of the 5 In refrigerating systems It is a common pracunit taken on the line 3 3 of Fig. 2 with parts tice to provide coils or the like within the combroken away; I partment that is to be cooled and to circulate a Fig. 4 is a section through the lower margin of cooling medium or refrigerant through said coils a heat absorption plate of the cooling element to cool the air in the compartment, rsuch coils taken on the line 4-4 of Fig. 2; and I0 usually being provided with plates or ilns thereon Fig. 5 1S a fragmentary Sectional View 0n the to increase the cooling surfaces to which the air line 5 5 of Fig. 2 showing the manner of attachis exposed.

These tubes are mounted in and project away. The facilities forlcollecting and draining through end plates 9 and I0 and are connected 2o away the moisture must, however, be arranged in series by return bands II at their ends beyond 2d surfaces thereof that do not drain into the regucirculated through the connected series of pipes 25 and conveniently cleaned. the end plates 9 and III and securely xed on The principal objects. of my invention are to the pipes 1 and 8 in a manner to insure good con- 30 provide improved moisture collecting and drainductivity.
