Depending on the application the design of the evaporator will differ. In the first part of this chapter different types of evaporators are presented and their applications discussed. The presentation will then focus on methods for calculating heat transfer and pressure drop, both on the refrigerant side and on the heat source
Selecting the best evaporator for a given application can sometimes be a confusing and even intimidating task. Technical terms like falling film, forced circulation flash, and multiple effect can add to the confusion. In this article we will take a brief, not-too-technical look at the most common types of evaporators, how they.
Types of evaporators 1. Natural circulation type – a) Vertical short tube or Calandria evaporator b) Long tube vertical (LTV) rising film type c) Long tube vertical (LTV) falling film type 2. Forced Circulation type Calandria Evaporator It has a vertical tube bundle consisted of short tubes (usually less than six feet) integral with the
Classify refrigerant evaporators as natural convection or forced convection type, flooded or dry type, refrigerant flow inside the tubes or outside the tubes. (Section 23.1). 2. Discuss salient features of natural convection coils (Section 23.2). 3. Discuss salient features of flooded evaporators (Section 23.3). 4. Discuss salient
Types of Evaporators. This bulletin is intended to provide an introduction to the primary types of evaporators which are implemented in various industries today. Every evaporator design will have a means of transferring heat energy through a heat transfer surface as well as a means to effectively separate the vapors from the
CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF EVAPORATORS. Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration, process. We define the evaporation process as one that starts
if the equipment manufacturer is able to offer a full selection of evaporation technology and systems developed to accommodate various product characteristics, the percent of concentration required, and regional energy costs. This handbook describes the many types of evaporators and operating options available through
Evaporator Types and Applications 71 for products that require large residence times, or for products that are difficult to handle. A more frequent method of operation is semibatch in which feed is con- tinuously added to maintain a constant liquid level until the entire charge reaches the final concentration. Continuous—batch
11 Jan 2010 Types of Refrigeration Evaporators. This article describes various types of refrigeration evaporators like bare tube, plate type and finned type. Different types of evaporators are used in different types of refrigeration applications and accordingly they have different designs.
4.1 Natural/forced circulation evaporator. 4.2 Falling film evaporator. 4.3 Rising film (Long Tube Vertical) evaporator. 4.4 Climbing and falling-film plate evaporator. 4.5 Multiple-effect evaporators. 4.6 Agitated thin film evaporators.
