evaporator liquid boils, it forms bubbles of water vapor in the liquid much like a pan cooking on a stove. As these bubbles reach the surface of the evaporator liquid and burst, the escaping water vapor carries some of the evaporator liquid with it. The final requirement for an evaporator, then, is a means of separating the evaporated water
† There are two main evaporator designs; the dry evaporator (2) and the ﬂooded evapo-rator (3). In a dry evaporator, we generally get some super-heating, whereas there is no (or little) super-heating in a ﬂooded evaporator. The latter design is better thermo-dynamically, because super-heating is undesirable from an efﬁciency (COP) point of
The total volume of product in the evaporator system increases with the number of effects connected in series. This is a drawback in the treatment of heat-sensitive products. However, evaporators with four to seven effects and additional finishers have been used in …

This is the first Article in our new Course HVAC-2: Electrical Rules and Calculations for Air-Conditioning Systems, which will list, explain, and discuss with examples all the topics covering the Electrical Rules and Calculations for Air-Conditioning Systems which will include but not limited to the following points:. Introduction for Air-Conditioning Systems types,
The low-pressure line is an evaporator (it absorbs heat) and the high pressure line is the condenser (it rejects heat). The first heat exchange that occurs in this basic refrigeration cycle is the evaporator. The air conditioner evaporator is locate between points six and one in the basic refrigeration cycle diagram.

A capillary tube is used between the condenser outlet and evaporator inlet of a domestic refrigerator working as simple expansion device in vapour compression refrigeration system (VCRS) to drop the pressure and the corresponding saturation temperature of refrigerant from condenser condition to the evaporator condition.
The proper design of the product distribution system in the head of the evaporator is critical to achieve full and even product wetting of the tubes. Because of the low liquid holding volume in this type of unit, the falling film evaporator can be started up quickly and changed to cleaning mode or another product easily.
