The Brazed Heat Exchanger – less is moreThe brazed plate heat exchanger is the most

compact heat exchanger on the market today.

Its high heat transfer efficiency in combination

with its compact design equals a compact heat

exchanger for a wide range of heating, cooling,

evaporating and condensing duties.

The brazed heat exchanger consists of thin

corrugated stainless steel plates brazed together

with copper to form a self-contained unit. Brazing

the plates together eliminates the need for a

frame, gaskets, bolts and the carrying bar. The

result is a heat exchanger that costs less, weighs

less, holds less refrigerant and takes up less space.

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 expan-sion device and connecting pipes. These are the mini-mum 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

point. Other properties can then be plotted as param-eters, e.g. isotherms, lines of constant temperature. In the figure, the -13 °F isotherm is shown. It is almost ver-tical 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 com-pression would follow this line (D - E´), but because of the inevitably released friction energy, a real compres-sion is (D - E), i.e. to a higher final temperature.

Economizers/Subcoolers

The Economizer/Sub-Cooler Refrigeration CycleThis 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 compres-sor 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.

This is principally the basic refrigeration cycle, but with a desu-perheater/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 com-pressor. 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, pos-

sibly 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.

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 orc. back through the condensate pipe to the condenser exit and into the channels from below

The Oil Cooler

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 compres-sor 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 evapora-tor, depleting the oil content in the compressor.

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 ef-fective oil separator cannot capture all the oil; some will inevitably leave the separator and ultimately the oil is con-centrated at the evaporator-separator loop.

The second step is then installation of an oil return evapo-rator.

Radiant Floor/Snow Melt Heat Exchangers

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 con-cerns, many hospitals and commercial building pump warm glycol to heat the sidewalks and entryway rather than utilize water to melt snow and ice.

CombiDryers DIMENSIONS AND SPECIFICATIONS

General

Providing you with Heat Exchangers and added value acces-sories in the compressed air market- Alfa Laval offers a com-plete range of Combidryers for refrigerated air dryers.

Alfa Laval is committed to optimizing the performance of yourprocesses, with complete dedication to your business. The Combidryer is a brazed plate heat exchanger designedspecifically for compressed air dryers, consisting of both theair to air and the air to refrigerant heat exchanger.

Easy installation of the separator is accomplished throughconvenient connection locations.

Combidryers are designed for high thermal performance and low-pressure drop, covering a capacity range from 37-1400 Nm3/h (22-825 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 pressuredrop minimizes power usage.

• Full compatibility with the most common refrigerants.Application refrigerated air dryer (Figure 2)

Refrigerated air dryers separate humidity from compressed airby cooling the air in an evaporator. This cooling effect comesfrom the evaporation of the refrigerant. As the air cools, itlooses 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 airto ambient temperature is in the Combidryer for optimal efficiency.

The coldest temperature in the system determines the "dewpoint". "Dew point" is the temperature at which the watervapor in the air starts to condense in the water separator.This is normally maintained slightly above the freezing point ofwater, 2-5 °C (35-40 °F).

As you can see in the picture to the right, the humid airenters into the heat exchangers and cools down in the air torefrigerant.This humid air then moves into a separator and then dry air ispreheated in the heat recovery side. The total air side pres-sure drop is typically 20-30 kPa (3-4 psi)

Figure 1. The heating surface consists of thin corrugatedstainless steel plates that are compressed together to form a plate pack. Channels are formed between the plates and the ports are

arranged so the media flows through alternate channels in fullcounter current flow. Media is directed by a brazed seal enhanced with contact points to contain the media flow pressure.
