How it works:

The basic principle of how Solar Air Conditioning works.


Why Solakool?

Solar Hybrid technology brings the cost of air conditioning down.Consumers are now able to cool and heat their homes without itcosting them an arm and a leg. The large scale deployment of thesesystems will bring a benefit in the reduction of CO2 levels producedexceeding almost all other forms of renewable systems.

However, one of the most important results from this large scale up-take is that when used throughout the day as advised by CSE, thesudden high energy usage caused by consumers returning homefrom work and turning on the air conditioning to full power iseliminated. This will make it easier for the Utility companies toproduce enough energy from their current infrastructure andtherefore reduce the need to increase the cost of electricity to forcea reduction in demand.

All levels of Government should be informed and requested tosupport the large scale uptake of these systems as the benefit isaccrued to the whole community including the Utilities andGovernment.

The basic working principle of solar air conditioning


Summary of Operation:

In a SOLAKOOL Solar Air Conditioning System the sun is used as a heat source toreduce the energy needed to drive the cooling process of a typical airconditioning system which in turn reduces the electrical energy required to runthe compressor.

The SOLAKOOL Solar Air Conditioning System is similar to a standard a/c in thatthe refrigeration takes place by evaporating liquid with a very low boiling point.In both cases, when a liquid evaporates or boils, it absorbs energy in the form ofheat and can continue to do so either until the liquid is all boiled or untileverything has become so cold that the sub-zero boiling point has beenreached.

The difference between the two is how the gas is changed back into a liquid sothat it can be used again. A standard air conditioning system uses acompressor to increase the pressure on the gas, so that when it enters thecondenser coil the combination of pressure and cooling from ambient aircondenses it into a liquid in the coil. The change of state of the refrigerant startsto take place approximately 2/3rds of the way down the condenser.

The SOLAKOOL Solar Air Conditioning System improves on this basic method byusing the heat from the sun to add thermal energy to the refrigerant vapourwhich increases the difference in temperature between the refrigerant and theambient air hastening condensation. It also increases the refrigerant pressure byexpansion which all means that the refrigerant now begins changing state in thetop 2/3rds of the condenser coil.

By using this method it reduces the superheat of compression required toachieve the cooling process in the conventional cooling system as well asutilizing more of the cooling face of the condenser coil.

The conventional cooling system is only able to change a portion of the gas intoa liquid state so that as it enters the metering device, or capillary, it is asaturated vapor.

The SOLAKOOL Solar Air Conditioning process allows more of the refrigerant tochange state back into a liquid faster as well as allowing the transformation ofmore liquid into the metering device.

In our solar ac system the low pressure, low temperature refrigerant iscompressed before gaining solar thermal energy in the heat exchanger of thesolar absorption panel so that we now have both higher pressure and highertemperature vapour.


Then the vapour is condensed into high pressure liquid at ambient temperatureby passing through the condenser.

The high pressure liquid is converted into low pressure, low temperature vapourat room temperature when it passes through the capillary before entering thefan head.

This is achieved by throttling and decompression of the liquid into vapour at lowpressure and low temperature in the capillary.

This phase change absorbs energy out of the room in the evaporator inside thefan head.

Air is blown through the condenser to distribute the cooling throughout theroom.

Moisture forms on the surface of the evaporator coil where it is piped away tothe nearest storm water drain.

In the heating cycle the condenser and evaporator are reversed in sequenceso that heat energy is released in the fan head instead of outside.

The warranty time for SOLAKOOL solar a/c is 5 years and the designed servicelife is 30 years. Most components are readily available locally, however, they arecovered by the warranty in the warranty period.

4. Does the solar collector need any special maintenance?

NO special maintenance is required once installed.

5. Is the SOLAKOOL solar a/c 100% solar?

No. It still requires electric power to operate the compressor and the fans.However, combine the SOLAKOOL solar ac with the SOLAKOOL solar thermalpower system and you have a completely solar system.

6. How does the SOLAKOOL solar a/c work at night and in cloudy weather?

The SOLAKOOL solar air conditioner works day and night and in rainy or cloudyweather. The solar panel will absorb and store solar thermal energy during theday. It only requires 4-5hours of sunlight for 15hrs continuous operation.

7. What is the difference between Inverter a/c and solar a/c?

Inverter technology enables the a/c to operate at the most efficient compressorand fan speed when below full power. At full power it has no advantage overconventional a/c. Typically, an inverter will save up to 15% of the electricityrequired to operate except when it is on full power.

A SOLAKOOL solar a/c will save up to 80% over a conventional a/c andeliminate the high air conditioning demand at peak times.

Supporting Data:

Heat TransferHeat transfer, or heat exchange, is a process of "heat migration" from one point,to another.

From a point of higher temperature to a point of lower temperature.

Tell me about heat transfer from the beginning, please.

What if I start at energy?

Energy is “the ability to do work”.

Work, in simple terms, is defined as force (F) applied to move any object, by adistance (x).

Hence, if the force required to move the object is larger, i.e. moving a train thenthe work done per distance moved is much larger than moving a bag of cotton.

The indestructible nature of energy:

Every atom has an internal energy.

This is due to the continuous motion of electron/s orbiting the neutron/s andproton/s. Electron has its own mass to move, so force is required. Electron has itsown distance to move. Hence, energy is existent.

As long as the basic of all building blocks, namely electron, proton, and neutronexist, energy can neither be destroyed nor created.


Therefore, energy can only be transformed from one state, to another:

Consider a sample of gas, with a specified internal energy. Consider anothersample of gas with lower internal energy. Now, due to the internal energy fromthe electrons, atoms or molecules will move in a specified random motion. TheSpeed that these particles (atoms or molecules) move, will depend on theinternal energy. The higher its internal energy, the higher the speed of theseparticles.

Back to our samples of gas.

When these gases are brought into contact, the gas particles will start to collidewith each other. Gas particles with higher internal energy, will collide with gasparticles with lower internal energy.

Speed of these particles will be traded. The lower particles’ will increase inspeed, and the higher gas particles’ speed will reduce speed.

Analogy

It is analogous to what happens when a white ball in snooker game hits a packof snooker balls. Initially, the white ball will have a very high speed. As it impactsthe pack of balls (which are initially at a standstill), the white ball will loose itsspeed tremendously, and the rest of the pack will gain some speed.

This is an example of how energy is transferred from one state, to another.

So, how can you say that heat is a form of energy?

A specific sample of gas, with temperature above 0 Kelvin, and a finite mass;has particles vibrating, rotating, or travelling at a high speed. In other words,these particles are moving.

Since these particles are in motion, the gas particles are doing work! Therefore,heat is a form of energy.

Change gas to liquid giving you cold :

Manufacturers of air conditioners use refrigerants because they have anattractive boiling temperature for heat exchange between air that we live in,and the refrigerant.

But, our atmospheric condition will not allow refrigerant to be in liquid state.Hence, we need to compress it enough, coupled with condensing it, to changethe state from gas, to liquid. The energy from compression and condensationovercomes the internal energy of the refrigerant. Hence the state is changedfrom gas to liquid through compression and condensation.

This stage is coupled with compression, for two reasons:

1. to change the refrigerant’s state from high pressure gas to high pressureliquid

2. to avoid having a very large compressor to compress refrigerant beyondcritical point – i.e. change gas to liquid without going through liquid-vapour phase. In other words, ensuring air conditioner efficiency.

Although compression alone may changethe state of refrigerant from vapour to liquid,it is not efficient. A large amount of energy isconsumed and you might not get cool air inthe end. So, condensation is required.

Condensation happens mainly in a heatexchanger, through a heat exchangeprocess. The heat exchanger is known as thecondenser.




















Sneak peek into the basics:

Every atom and molecule of matter has a specific internal energy, as explainedin the compression page. And due to this specific internal energy, differentmatter exists in different states (solid, liquid, or vapour) at a given pressure andtemperature.

Solids will have atoms or molecules packed together very closely, hence themovement only involves rotation about each atom or molecule’s axis.

Liquid however, will have a close formation of molecules or atoms. Themovement is much more flexible than solids, but still restricted to short distances.Liquid has higher molecule or atomic energy compared to solid, but lowerenergy compared to vapour.

Vapour has all the freedom in this world, to move in all directions possible, withlarge distances between each atom or molecule, high speed and random inmotion. It has the highest molecular or atomic energy between solid and liquid.

Our interest is in vapour and liquid phases, and the phase in between. Thephase in between? Keep reading.

Condensation:

Condensation is defined as the state, when a vapour starts to change phaseinto liquid state, as a result of temperature drop.

It starts when a superheated vapour reaches its saturation point.

We have to bear in mind that condensation does not occur at a singulartemperature. It occurs at different ranges of temperature. Reason being, thepressure of the vapour itself.

The compression page has explained that increasing the pressure will reducethe distance between the vapour molecules. Thus, vapour molecules will havelower net energy.

Decreasing the pressure will have a reverse effect, where the distance betweenthe molecules will increase, and net molecular energy will increase.

So, if a gas or vapour has a higher net energy, more energy needs to beremoved to reduce the distance between the molecules.


Similarly, lower net energy of vapour requires less energy removal for moleculesdistance to close.

What’s with all the molecule distance and energy removal?

As explained earlier, the molecule distance is a characteristic of different statesof a matter. Solid, liquid, or vapour.

Energy can be in terms of work, or heat. And when condensation is in thepicture, energy removal is in terms of heat.

Hence, as the pressure of the vapour increases, the heat removal required issmaller to condense it. This means that condensation of the matter starts tohappen at a higher saturation (or boiling) temperature. This is good, as anytemperature lower than the saturation temperature, means we will have acondensed liquid.

The flip side occurs for low vapour pressure.

Let us consider Refrigerant 12 as an example.

Referring to Rogers’ and Mayhew’s “Thermodynamic and Transport Properties ofFluids”:

the saturation temperature at 1 bar is about -30 oC whereas the saturation temperature at 9.6 bar is about 40 oC

This means that we have to have ambient air at -30 oC for condensation of therefrigerant to occur at ambient pressure.

Well, if we have that kind of ambient temperature, we wouldn’t need coolinganymore would we?

You see, the ambient temperature for the compressed refrigerant does nothave to be very low for condensation to occur. In fact the saturationtemperature is higher than most ambient temperatures during hot summer.Hence heat exchange occurs from the refrigerant, to ambient air.

This is why we have to couple condensation with compression in air conditionersystems.

Bring the pressure up, close the gap between the gases, and remove the heatfrom the refrigerant to close the gap even more – we have liquid refrigerant!


Vapour, liquid and the phase in between:

This occurs when heat is continually removed from the vapour.

If all of the matter is in vapour form, then we call it superheated vapour, as thereis no condensation.

Once the temperature drops to saturation line, we will have a mix of vapour andliquid. This is the phase in between.

At this time, temperature will not drop.This is due to energy consumption ofthe atoms or molecules to bond andchange phase from vapour, to liquid.

Temperature will not decrease until all vapour within an enclosed space isturned into liquid. This is the phase change.

Once in liquid form, the temperature will start to decrease again, until it meetsfreezing point. But that’s a different story.

Condensation in a real life example:
