ABSTRACT: Vapour compression refrigeration system using chlorofluorocarbons

is harmful to the environment and destructive to the ozone layer. It also consumes

more energy than others energy consumption utilities. This concerns lead to the

development of solid sorption refrigeration system which is environmentally

friendly and could be driven by low waste heat energy. Due to the availability of

waste heat from fishing boat, adsorption system has been proposed to be an

alternative refrigeration system on the boat. Meanwhile, various kinds of

adsorbent-adsorbate pairs have been developed. The most common pairs are silica

gel-water, activated carbon-ammonia, and activated carbon-methanol pairs.

In order to make the system more compact, the heat transfer flux in and out of

the adsorbent must be high. Therefore, a compact heat exchanger shell and tube is

proposed to work as a generator. A zeolite-methanol is selected as adsorbent-

adsorbate pair. Zeolite is coated on the tube inside of the heat exchanger. The heat

transfer in the generator is calculated. The highest rate of the heat transfer is 268.23

W/m2∙K when the heating temperature of water is 100

oC and the water mass flow

rate is 0.5 kg/s.

Keywords: adsorption, generator, adsorbent-adsorbate, coating

Refrigeration has applications embracing a huge range of fields in which we all

encounter in our daily lives and therefore plays an essential role in sustainable development.

Unfortunately, the common refrigerants such as CFCs and HCHCs refrigerant have the global

warming potential and thus contribute to the greenhouse effect. The discovery of ozone

depletion caused by those refrigerants led to the Montreal Protocol, which schedule to phase

out CFCs by the end of 1995, HCHCs by the end of 2030. Furthermore, refrigeration systems

are used in various sectors and they are the primary of energy consumption. With the

increasing of energy consumption worldwide, it is becoming more urgent to find way of using

the energy resources as efficiently as possible. Thus, machine that can recover waste heat at

low temperature level, such as adsorption machine, can be an interesting alternative for a wiser

energy management.

Sine the interest in adsorption systems was renewed in the last 20 years, the COP and SCP

of these systems greatly increased due to the works of several research groups. Wang and

Olivera [1] have conducted a study of adsorption refrigeration. They showed that consolidated

compound adsorbents have shown their potential to increase cooling performance of the

adsorption refrigeration system and the COP is 0.4 for evaporating temperature is -15.

Jribi et al [2] studied about the performance of a two-stage activated carbon-CO2 adsorption

system. The adsorption uptake is carried out for the temperature range from -18 to 80oC. The

maximum COP is 0.16 for the evaporator and desorption temperature of 15oC and 80

oC,

respectively. To improve the over performance of adsorption refrigeration system, different

construction of bed have been designed [3, 4]. Waszkiewicz et al. [11] reviewed an adsorption

refrigeration system using zeolite and methanol. The analysis confirms that large changes on

COP are possible. Typical estimates are 0.535 for a single bed cycle and around 0.935 for a

twin bed cycle.

In this work we present the analysis of a novel twin bed adsorption system. By using two

beds, heat rejected from the first bed can be recuperated and used to regenerate the second, the

limitation of mass and heat transfer is diminished. The design is based on the technology of

coating zeolite paste on substrate [5, 6].

2. WORKING PRINCIPLE OF ADSORPTION SYSTEM

Physical adsorption: Adsorbent (solid) has physically high porous structures with surface–

volume that can catch and hold refrigerants (vapor). When saturated, it can be regenerated

simply by heating.

There are three main components in the system: a generator, a condenser and an evaporator.

The generator is capable to adsorb and desorb vapor refrigerant when it is being cooled and

heated, respectively. The generator works as a thermal compressor by adsorbing refrigerant at

the evaporating pressure and desorb the adsorbed refrigerant at the condensing pressure. The

high pressure refrigerant leaving from the generator will be condensed in the condenser by

isobaric process. The liquid refrigerant at high pressure leaves the condenser and expanses to

evaporating pressure so that the refrigerant evaporates in the evaporator where the cooling

effect take place. The evaporating vapor refrigerant will be adsorbed in the adsorbent surface

volume and then desorbed again to complete a cycle in the adsorption process. The process is

intermittent for a single generator system because the adsorbent in the generator have to be

cooled in adsorption process and heated in desorption process at different time. Multiple

adsorbent beds are required for continuous operation [7].

3. ADSORBENT-ADSORBATE SELECTION

In this study zeolite-methanol is selected as the adsorbent-adsorbate pair. It is expected to

work in better coefficient of performance because the regeneration temperature is as low as 100 oC for the refrigerant to be fully generated and with this temperature does not causes methanol

to decompose. The difficulties of selecting an adsorber pair refrigerant are the limitations of

heat transfer coefficient of adsorbent and the generating temperature of the adsorbate. Various

feasibilities of adsorbent-bed design have been proposed and developed to improve the heat

transfer inside the generator. Zeolite is an adsorbent material that can be prepared for coating

on a substrate surface [3, 7].

The refrigerant is basically selected upon it heat capacity, evaporating temperatures and

pressures, environmental impact and its ability to be adsorbed on adsorber. Water is generally

not useful for high heat load. Ammonia has a more favourable specific volume but is toxic and

corrodes copper and brass fittings. Most alcohol are environmentally friendly but are

dehydrated and catalytic decomposed during desorption at 150 - 200oC. Compared to

ammonia, methanol is more compatible and less toxic. The normal boiling point of methanol is

64.7oC and the low melting point is -93.9

oC is convenient for a refrigeration of subzero

evaporating temperature. Zeolite-methanol pair was also selected by Waszkiewicz [11] and it

gives the best coefficient of performance of 0.5 for a single bed cycle [9, 10] and it can be

improved to 0.935 for a twin-bed cycle.

4. GENERATOR DESIGN

Generator is the main component of adsorption refrigeration system which dominates the

overall performance of the system. Maximizing the heat transfer coefficient is the difficulties

of generator design while adsorbent is known as a low thermal conductivity material.

Schematic diagram of a novel twin beds adsorption system is shown in the figure 1. The

system consists of two beds, a condenser, and an evaporator. The system is continuous while

one bed is cooled for adsorption and another one is heated for desorption. Periodically, V-5 is

opened to allow the beds to achieve the equilibrium.

Figure 2 shows the cross section of a shell and tube heat exchanger (generator). The

generator is simply designed as part of the refrigeration system. The length is 0.326 m and the

shell inner diameter is 1.79 m (15.25 in). There are 103 aluminum tubes with outside diameter

of 25.4 mm (1 in) and thickness of 3 mm (0.12in). Outside surface of the tubes is coated with 2

mm thickness of zeolite 4A paste. The volume of adsorbent is 0.04 m3 which equals to 106.72

kg and it could adsorb 18.65 kg of methanol on its porous surface at the ambient temperature.

The shell side is used to maintain the methanol vapor pressure when the bed is heated. Heating

and cooling fluid is flown inside the tubes for desorption and adsorption process, respectively.

4.1.Heat transfer coefficient in the generator

The inside tube heat transfer coefficient of the generator which is coated with layer of

zeolite paste is calculated using the Dittus-Boelter equation for getting Nusselt number as

given by equation (1).

If the velocity of the water is 0.02 m/s, the heat transfer coefficient of water can be

calculated for heating and cooling at different temperature. The results are graphically

represented in figures 3. The expected heat transfer coefficient is high for higher water

temperature and low for the increasing tube diameter. Another prediction of the heat transfer

with water temperature is shown in figure 4. It was plotted for a fixed tube inner diameter of

Quantity of adsorbed methanol increases with higher saturation temperature during adsorption

and decreases with higher generating temperature during desorption as shown in figur5. It

means that the higher saturation and generating temperature, the larger quantity of methanol

circulate in the system. For adsorption temperature is 35oC and desorption temperature is 90, it

is impossible to set the evaporating temperature lower than -20oC as confirm in figure 6.

6. CONCLUSION

All the work presented here shows the importance of properly designing parts the adsorption

refrigeration system, mainly the bed. The evaluation has shown that the system has a potential

to be manufactured as compact system which suitable for domestic uses as it has a high system

performance. The COP of the system is 0.652 which is around a double COP compared to a

single bed cycle. Somehow, there are some points that should be more studied such as the

following:

Adsorbent-adsorbate pair should be more studied to suit the refrigeration system of lower

evaporating temperature such as freezer, for which temperature need to be lower than -20oC.

Shell and tube heat exchanger coated with zeolite paste is an interesting method and needs

further study to improve heat and mass transfer in the system.

Double twin beds system is also interesting to be studied as it is capable to recover heat in

the system and it can be operated continuously.
