3 The Brazed Heat Exchanger less is more The brazed plate heat exchanger is the most The brazed heat exchanger consists of thin compact heat exchanger on the market today. corrugated stainless steel plates brazed together Its high heat transfer efficiency in combination with copper to form a self-contained unit. Brazing with its compact design equals a compact heat the plates together eliminates the need for a exchanger for a wide range of heating, cooling, frame, gaskets, bolts and the carrying bar. The evaporating and condensing duties. result is a heat exchanger that costs less, weighs less, holds less refrigerant and takes up less space.

5 The Basic Refrigeration Cycle The function of the refrigeration plant is to remove heat from a process fluid or air at a low temperature and transfer to a recipient fluid such as water or air. The figure shows a schematic cooling plant, composed of an evaporator, a compressor, a condenser, an expansion device and connecting pipes. These are the minimum components necessary in the basic compression refrigeration cycle. The pressure is shown as a function of the enthalpies of liquid and vapor. To the left of the liquid line is liquid and to the right of the vapor line, vapor. Between the two lines is a two-phase area. The lines meet at the critical DX Evaporators/Chillers point. Other properties can then be plotted as parameters, e.g. isotherms, lines of constant temperature. In the figure, the -13 F isotherm is shown. It is almost vertical in the liquid area, mirroring the fact that the liquid specific heat is little pressure dependent. In the vapor area it is curved and inclined, i.e. the vapor specific heat is strongly pressure (and temperature) dependent. The figure also shows an isentrop, a line expressing a change of state, but where no heat energy is exchanged between the fluid and the surroundings. An ideal compression would follow this line (D - E ), but because of the inevitably released friction energy, a real compression is (D - E), i.e. to a higher final temperature.

11 The Economizer/Sub-Cooler Refrigeration Cycle This is principally the basic refrigeration cycle, but with a sub-cooler added to the main condenser. A BPHE condenser is used to de-superheat and condense the refrigerant. The refrigerant leaves condenser at 95 F. It is then further subcooled to 64 F with well water of 59 F in the BPHE. Furthermore, the system efficiency and capacity are enhanced due to these effects. The lower temperature to the expansion valve means that less refrigerant has to evaporate in order to reach the evaporation temperature. Consequently, more liquid refrigerant is available in the evaporator, and its capacity increases. The increased efficiency of the compressor means that less compressor power is necessary. The actual performance of the cycle obviously depends on the total required capacity, the efficiency of the compressor for the actual operating conditions, type of condenser and evaporator, availability of water, available space, etc. This kind of refrigeration cycle layout is very useful for low temperature applications such as supermarket and food processing.

13 The De-super Heater/Heat Reclaim Refrigeration Cycle This is principally the basic refrigeration cycle, but with a desuperheater/heat re-claimer introduced between the compressor stages. A further improvement is the use of a two-stage compression, either with two compressors in series or in a two-stage compressor. The desuperheater between the compressor stages is only possible for a compressor where the first stage vapor leaves the first stage and then enters the second stage, possibly together with additional intermediate pressure vapor but not for a compressor with only an intermediate vapor inlet. The first stage vapor leaves at about 95 F and is cooled in the BPHE at about 64 F also with well water. The higher vapor density increases the amount of refrigerant in the second stage i.e. higher capacity. The higher vapor density decreases the refrigerant volume in the second stage, i.e. a smaller compressor.

15 The Oil Cooler The system is the same for both a soluble and an insoluble oil. The oil is cooled by evaporating warm condensate. The other possibilities, cold refrigerant or water, give larger thermal shocks. After evaporation, the vapor is condensed in the condenser again. It returns to the condenser either via: a. the LR and the equalization line (EQL) b. directly back to the condenser inlet or c. back through the condensate pipe to the condenser exit and into the channels from below The Oil Evaporator The vapor-liquid mixture leaving the evaporator enters the separator, where the vapor is separated from the liquid and possibly further dried in a demister. This separation will, of course, not only separate the liquid refrigerant from the vapor but also the oil from the vapor. Only the pure dry vapor is then returned to the compressor and thus oil entering the evaporator-separator loop will effectively be trapped there. If no special measure is taken, the oil concentration will gradually increase in the evaporator, depleting the oil content in the compressor. Hydraulic Oil Coolers The first step to be taken is installation of an effective oil separator after the compressor. However, this measure is not sufficient. Even a highly effective oil separator cannot capture all the oil; some will inevitably leave the separator and ultimately the oil is concentrated at the evaporator-separator loop. The second step is then installation of an oil return evaporator. 26.6/28.4 F Pressure drop creating valve. 26.6/29.8 F 106.7/214.3 F Oil filter 107.6/205.5 F 38.1 F 28.4 F 28.4 F F Oil tank 107.6/214.3 F Oil evaporator Vent EQL LR Condensate column 98.6 F V2 V1 Oil cooler Oil pump 98.6 F 28.4 F Oil cooler and oil return evaporator in flooded system with soluble oil.

17 Radiant Heat & Snow Melt The basic heating system illustrated here includes various brazed heat exchanger applications including domestic hot water supply, radiant floor heating, snow melt for outdoor parking areas and walkways. This system offers one of the newest and most efficient methods to provide comfort heating. This heating system is very popular in Northern Europe but is quickly catching on in colder climates in North America. Boiler water at 180 F is used to heat the water that is pumped to the various applications. Due to safety concerns, many hospitals and commercial building pump warm glycol to heat the sidewalks and entryway rather than utilize water to melt snow and ice.

31 Providing you with Heat Exchangers and added value accessories in the compressed air market - Alfa Laval offers a complete range of Combidryers for refrigerated air dryers. Alfa Laval is committed to optimizing the performance of your processes, with complete dedication to your business. The Combidryer is a brazed plate heat exchanger designed specfically for compressed air dryers, consisting of both the air to air and the air to refrigerant heat exchanger. Easy installation of the separator is accomplished through convenient connection locations. Combidryers are designed for high thermal performance and low-pressure drop, covering a capacity range from Nm3/h ( scfm). Features and advantages Compact size: - reduces the total air dryer size - significantly reduces the refrigerant hold-up volume Highly efficient thermal performance and low pressure drop minimizes power usage. Full compatibility with the most common refrigerants. CombiDryers Application refrigerated air dryer Refrigerated air dryers separate humidity from compressed air by cooling the air in the evaporator. This cooling effect comes from the evaporation of the refrigerant. As the air cools, it loses its ability to hold moisture. The condensate is then collected and removed in a separator. A heat recovery air to air heat exchanger that reheats the air to ambient temperature is in the Combidryer for optimal efficiency. The coldest temperature in the system determines the dew point. Dew point is the temperature at which the water vapor in the air starts to condense in the water separator. This is normally maintained slightly above the freezing point of water, 2-5 C (35-40 F) As you can see in the picture to the right, the humid air enters into the heat exchangers and cools down the air to the refrigerant. DIMENSIONS AND specifications This humid air then moves into a separator and then dry air is preheated in the heat recovery side. The total air side pressure drop is typically kpa (3-4 psi) Figure 2

33 The Alfa Laval insulation provides protection for the heat pack and minimizes additional heat to the surroundings or room. The insulation kit is easily applied and removed with opening and cuts-out in the proper location for the unit. This allows the insulation to be installed on the heat exchanger in place. The insulation material used with most models is a NBR-based closed cell foam having a thermal conductivity of BTU/Hr.- Ft.-F. The standard insulation is good up to 220 F.
