Clean System Energy (CSE), is a Brisbane based company. Our motivation is to reduce the impact we have on our environment and reduce the cost of living by using free energy and optimising efficiency of systems we use in everyday life.

Our products all focus on using free or renewable energy and increasing system efficiency which in turn reduces the cost of living for families, businesses, companies and communities.

Introducing our Multi-head Solar Air Conditioning system:

Conventional multiple head air conditioning systems such as VRF or VRV systems, use large volumes of ozone depleting refrigerant to provide the cooling effect at each fan unit. In ducted systems, large ducts are used to carry the cooled air to diffusers in each location where cooling is required. The must be pressurised so that sufficient cooled air is circulated. If the return air flow path is blocked, by a door being closed for example, the room will pressurise to the maximum and then no further cooling is possible.

Solakool MSAC In the Solakool MSAC, a small volume of refrigerant is kept within the body of the condenser pipework, reducing the chance of release into the atmosphere and reducing the cost of large volumes of refrigerant. This also simplifies installation as all is installed at the factory and is within the body of the condenser.

The cooling effect is distributed in the form of chilled water that is circulated to air handling units as used in large buildings and hotels. Standard water pipes are used to connect the various components in the system, eliminating the need for copper pipe runs and reducing installation cost and time. 3 | P a g e © Clean System E nergy 2012 Commercial in Confidence The Multi-Head Solakool solar air conditioning system has the same solar boost technology utilised in the range of Solakool conventional Hi-Wall and Ducted air conditioning systems to produce the most efficient air conditioning systems listed on the Australian Government Energy Star web site that are tested at full power.

The pressure and heat produced by compressing the refrigerant vapour in a conventional air conditioner is replaced by adding temperature and pressure from expansion in the solar thermal panel thereby improving the condenser efficiency and reducing the run time of the .

The solar panel is integrated into the front of the condenser body adjacent to the condenser fans.

In the Multi-Head version the cooling effect is applied to a within the body of the condenser. Water is pumped into the heat exchanger where it is chilled. The chilled water is then pumped around a circulation loop through the air handling units in the area to be cooled. The total combined capacity of the air handling units is equivalent to the capacity of the condenser or less if zoning is built into the plan.

For example: In a condominium there is a requirement for 3 bedroom systems at 2.5kW each and a single 7.0kW system for the living area. This can be matched to either a 14kW condenser unit or a 7kW condenser if day/night zoning is contemplated. The rooms can easily be zoned in or out by turning the fans on or off as required. If the day zone is on by itself only 7kW is drawn from the condenser unit thereby requiring less energy for operation. 4 | P a g e © Clean System E nergy 2012 Commercial in Confidence Installation is much simpler as only a water pipe loop is required to carry the chilled water from the condenser around a loop to the fan units and back to the condenser again.

It also eliminates the need for copper pipes that would be required if individual, ducted or VRF systems were installed.

Fan units can be mounted where they can provide the best cooling outcome for the shape of room rather than conform to a particular space on the wall without consideration for the cooling efficiency.

Any size space can be configured using the choice of AHU’s from 1.8 to 12.6kW and condenser units from 7.2kW to 60kW.

Hydrocarbon Refrigerant The Solakool MSAC is designed to operate with Hydrocarbon Refrigerant instead of Hydrochlorofluorocarbons(HCFC), such as R22 or Hydroflourocarbon(HFC), blends such as R410a.

This significantly reduces the impact on our environment from leaking such as the hole in the ozone layer over the North Pole that has caused Greenland to be green for the first time in known history.

The operating pressure is lower and the volume of refrigerant required is significantly reduced. The electrical operating cost is reduced by up to 30% by the use of Hydrocarbon refrigerant.

5 | P a g e © Clean System E nergy 2012 Commercial in Confidence Hot Water Capture In addition to the chilled water supply, a further heat exchanger is included to capture heat produced in the operation of the condenser that would normally be blown away into the atmosphere with the fans.

Hot water is produced at 65degreesC and in the case of the 14kW system it produces enough thermal energy to maintain a 400litre tank at 65degreesC without the need for a booster element.

The hot water flow of 400l/hr at 65degreesC is produced independently of the operation of the air conditioner mode.

When this option is used, the overall efficiency of the system, EER, is dramatically increased as the same electrical input now produces air conditioning and hot water.

This also reduces the capital expense and installation costs of installing separate air conditioning and hot water units.

11 | P a g e © Clean System E nergy 2012 Commercial in Confidence Summary of Benefits:

 All refrigerant is contained inside the condenser body eliminating potential leakage into the atmosphere.

 Reduction in the amount of refrigerant required by the Solakool MSAC reduces the risk of damage to the environment and eliminates the risk of asphyxiation from a refrigerant leak.

 No copper pipe work required.

 Individual air handling units ensure that there is never a return air flow blockage.

 Individual controls enable complete control of individual units and zones.

 The use of hydrocarbon refrigerant reduces operating cost and the amount of refrigerant required at installation of the MAC system.

 Hot water produced as a bi-product of the operation of the system improves overall efficiency of the MSAC system and reduces cost of installation of two separate systems.
