The hot gas enters at thetop fitting of the coil and loaves atlower flitting. Cold water is constantly flowing in at the bot-tom of the tank and leaving by ithe overflow at the top, beingheated as it rises. The form of the coil is usually spiraL. Fig. 136. REFRIGERATION 291 although this condenser may be built with coils of the re-turn bend type when larger surface is required. Only thesmaller compression plants use the enclosed or the sub-merged type of condenser.
