Steam to be condensed enters at the top of a series of grilled tubes around which a film of cold water is falling. (ii) Steam should enter the condenser with the least possible resistance. Cooling water enters at one end of the tubes situated in the bottom half of the condenser and after flowing to the other end returns through the tubes situated in the top half of the condenser. The main principle of this condenser is that the momentum of flowing water removes mixture of condensate and cooling water against atmospheric pressure. If, therefore, the temperature of the condensate is tc and the temperature of cooling water inlet is t1, the coefficient of performance of a condenser is defined as under. Once the condenser water has cooled down, it returns then at a much cooler temperature ready to pick up more heat from the condenser again. Exhaust steam enters at the top and surrounds the cones through which cooling water flows at high velocity. The condenser sits on the back of a refrigerator, and is likely quite dusty. Prohibited Content 3. The cooling effect generated by the air conditioners is generated by taking away the warm air in the room through a simple yet effective procedure and dispensing it in the outside world. At. Condensers are classified as jet condensers and surface condensers. Absolute pressure in a condenser depends upon the amount of air present in it and temperature of the condensate. (4) There is pressure drop in the tubes when the steam flows over the tubes. The prevention of leakage of air in the surface condenser is difficult because of the presence of the high vacuum in the condenser. Air released from steam and water rises to the top thereby coming in contact with cold water and so it gets cooled and devapourized. Jet condensers in which cooling water, condensate and non-condensable gases are removed by a single pump are called low level low vacuum jet condenser because of limited air capacity of the pump. (2) Prevention of Air Leakage in the Condenser: In order to prevent the sources of leakage in the condenser the following procedure is adopted: (i) The design of condenser and use of vacuum joints. If during the desublimation the water is not converted into ice but frost, the heat transfer condition will worsen considerably. Well, here’s your chance to find out! Following approximately three injections (addition of 150 μL) of a cellular lysate or highly proteinaceous solution to the purge vessel, the triiodide reaction mixture and antifoaming agent will need to be replaced; otherwise a decrease in sensitivity is observed. When condenser is used in conjunction with a pumping engine, the reverse arrangement is generally provided i.e. Condensers are used for efficient heat rejection in many industrial systems. Add 4 ml triiodide reaction mixture and antifoaming agent to the purge vessel. The pressure in the condenser depends on the amount of air. From stage 4 to stage 1, heat is given off through the condenser, thus. Fig. Steam enters from the bottom of the condensing chamber. This setting which is different for each objective depends on what information one needs to obtain from the observed specimen. In this condenser supply of cold water into the condenser chamber is drawn due to vacuum. Afterwards the steam supply from the engine is shut-off; simultaneously the air and condensate extraction pumps are closed down so that the condenser is isolated. Intercondenser.

The condenser fins need be kept clean to maximize heat transfer and cooling effect on the refrigerant. The mixture of condensate and cooling water is removed from bottom by means of a pump.
