This invention relates to condensers, and

more particularly to condensers forming-a v formed with a filler neck 18 adapted to be closed 'by'the cap 19 which screws thereon.)

; Mechanical"refrigerating systems of the domesticltype must be constructedto occupy .a limitedspace and at the sametime transfer heat quickly: during intermittent operation. .As a result it is substantially universal prac ti'se to employ copper as material; because ofits ,pliability andfast heat dissipating qualities, and also to associateeither running water or forced air inthermalcontact with the copper refrigerant container inforder to produ'cethe required heat absorbing efficiency. Copper is expensive, installation and operating costs of running water are high, while air forcing mechanism 1s an added expense, and therefore in order to meet requirements of space and e ficiency a material expense results.- An object of the invention is to materially lessen the cost of'condensers withoutsacrificing heat tra'nsfer efiiciency or Another object of-my'invention ing systems with which neither running Water nor forced draft is required in order to eifi ciently absorb heat from therefrigerant ing intermittently therethirough. i 30 A further object of the invention is toprovide acondenser for refrigerating systems of the compression type which will function eificiently and 'With a low head pressure.

In the accompanyingdrawings, I haveillustratedin vertical section a. condenser incorporating my invention.

The condenser comprlsesa container 10, a

refrigerant receiving vessel 11 arranged with-- (not shown). Atube 1e extends from the upper end of the vessel to the exteriorof the container, and a purgingvalve 15 isassociat ed with the protruding end of such tube. The inlet conduit terminates in an enlarged flared v I is to m vide a condenser for mechanical; refrigeratpass I with the liquid, condensed refrigeranhtoa portion 16 acrossthe open'end ofwhichis secured a1fine screen 17. The'containeris,

The refrigerant containing vessel is formed ofcopper, and is of a size such thatit'will' occupy only a minor portion of I thespace" Within the. container.

It

is well. known-that heat flow from acondensinggas withoutsuperheat through metal walls to an absorbing fliquidbccurs about five hundred times ;-as readily as heatlflow. from anon condensing or super heated gasthrough metal walls to alr, and therefore a very. small, amount 0f imetal area or wall'surface w th 2 high gas pressure is required in the vessel con- Obtain heat transfer required. 2Further, the condensercan bezformedsozthat the spaceoc- .cupied zthereby will add very littletothe -overall dimensions of .the cabinetwithwhich it i-SrlQO: be; associated.

struction. Because of this I am able to utilize a large amount of inexpensive low pressure surface for transferring heat from the water to the surrounding air and will obtain the required condensing without water or forced draft-,as the heatcapacity of the water in the container will take care ofthe excess heat flow from the vessel While the apparatus 0 rates intermittently. The surface area of t e container need'be' only sufiicient'to'provide for transferring the average'heat to'be dissipated during hot .weather, astheheat capacity of the Water will take care of the excess rate of heat transfer required during the intermittent compressor'operating periods.
