Frequently Asked Questions
What is the sound level?
When connected to ducts from the equipment to the conditioned space, the Climate Wizard indoor noise is almost inaudible. External noise measurements are given in the technical specifications.
Can you supply a fan airflow curve?
How much water does Climate Wizard use?
Water use is dependent upon the ambient temperature, the humidity, the set temperature on the wall control and for how long Climate Wizard is operated. In a typical hot summer day in Australia the water use will be in the order of 25 litres per hour for the CW-H10.
How efficient is Climate Wizard?
The coefficient of performance (COP) or the energy efficiency ratio (EER) is a measure of the efficiency of Climate Wizard, and the value can vary depending on the application and the climatic conditions. Typically COP values in the order of 10 to 15 are experienced (EER 34-50). This compares favourably with modern refrigerated systems that typically have COP values between 2.7 to 3.5 (EER 9 – 12).
How cold will the air be?
The supply air temperature will vary depending upon the initial ambient temperature and humidity. In most cases it will be much colder than the external ambient temperature. Typical temperatures are 10°C to 20°C (50°F to 68°F).
Will Climate Wizard cool my whole house?
Yes. To do that effectively, Climate Wizard needs to be matched to the heat load within your home. This is best done by formal calculation, taking into account the house design, materials used in construction, solar incidence and any internal heat loads. Your Seeley International dealer should be able to do this for you. Once the heat load and the climatic conditions of summer are known, then a correct equipment selection can be made.
How does the Climate Wizard work?
A fan forces hot outside air through a special heat exchanger core that has dry and wet channels. The design of the core produces very cold air that is delivered into the building.
What's the main advantage of Climate Wizard?
First, it has very low running cost.
Second, it helps to reduce greenhouse gases because the electricity used is small.
Third, it doesn't add any moisture to the air, so it creates comfortable conditions.
What technical documentation is available?
An APPLICATION GUIDE explains what the Climate Wizard is and how it can be applied, with worked examples. It also contains outlet temperature and Cooling Effect charts and a full description of the control system options.
A TECHNICAL SPECIFICATION document contains full performance data and dimensions.
A comprehensive INSTALLATION AND OWNER'S MANUAL covers every aspect of installation procedures, commissioning procedures, maintenance and operation procedures.
Does Climate Wizard work when it's very humid outside?
Yes it does, but with limits. Climate Wizard cannot remove moisture, but it doesn't add any moisture. In extremely humid conditions the temperature reduction may be small. But there is a big difference between ordinary evaporative coolers and Climate Wizard. Where the ordinary coolers stop working, Climate Wizard continues to cool the air noticeably and makes the Climate Wizard suitable for moderately tropical cities, eg Barcelona, Brisbane, New York, Rio, Mumbai, etc.
How does Climate Wizard save so much energy?
By cooling the air very efficiently, using water for the 'refrigerant', and requiring only a fan and small pump to operate. No compressor is required and that's what makes regular air conditioners so expensive to operate.
How does it reduce the energy consumption of an existing system?
Climate Wizard can produce cooling capacity much more efficiently than a refrigerated air conditioner, so when added to a refrigerated system the energy consumed for the original amount of cooling is much less than before the addition. Follow the link to find out more detail.
Is there any Legionella risk?
No. For a number of reasons there is no Legionella risk.
First, there are two chlorinators fitted into the water tank that constantly generate chlorine gas that kills bacteria in the same way as it does in city water supplies.
Second, the water temperature is lower than required for Legionella to grow.
Third, there are no aerosols created in the airstream to carry the bacteria downstream.
Why do you need a chlorinator?
Two automatic chlorinators are fitted in the Climate Wizard water management system in order to keep the water healthy, similar to the condition it is supplied from the city water mains.
Can I get a single phase model?
Currently Climate Wizard is only available in 3 phase configuration. This requires the three phases, plus neutral and Earth. Range 380 - 480 Volts.
How close together can I install Climate Wizard?
Climate Wizards CW-H models require clearance for maintenance at the sides and at the air inlet. Clearances are shown in the Installation manual. One metre from rear and 1.6m at sides.
Do I need an air filter on the inlet?
Climate Wizard models CW-H are supplied with a filter assembly on the inlet air as standard specification. The use of a filter is desirable to keep the cooler and the duct system clean. The filters are easily replaceable and are available as a spare part, from Seeley International Dealers. In practice if a noticeable drop in airflow is observed the first check should be to inspect the filters and clean them if necessary.
Can I install more than one Climate Wizard in my space?
Yes, multiple Climate Wizards may be used to condition the same space. They can be operated independently or through a building management system. Please refer to the installation instructions.
Is Climate Wizard available in other colours?
No. We only make it in Woodland Grey. However, it may be repainted. A good quality acrylic paint intended for external use, should be used.
Is Climate Wizard OK for houses?
Yes, however the models available at present may need a special site prepared for them. There is a special model for houses that is yet to be released. It will stand outside the house and ducts will carry the air into the building like a regular ducted air conditioner.
Can I duct Climate Wizard to various rooms?
Yes, Climate Wizard is very suitable for connection to ducts that may supply several rooms. It is necessary to conduct a proper heat load assessment in order to determine how many rooms can be supplied from Climate Wizard.
What is Climate Wizard?
It's a special kind of evaporative air cooler that produces much colder air than conventional evaporative air coolers and does not add any moisture in doing so.
Is there more than one model of Climate Wizard?
Yes, there are two types - one for houses (see the above question) and one for other types of buildings. They both look different - the one for houses is stands vertically and the other type is horizontal. There are two commercial models available.
Is it expensive?
Climate Wizard costs about the same as an equivalent sized air conditioner, but uses far less power to operate.
Can I integrate the Climate Wizard with heating equipment?
Yes. Customers are incorporating heating equipment by adding in-line gas furnaces, steam coils, hot water coils and electric elements downstream of the Climate Wizard and controlling the system with external PLC hardware and sensors. The Climate Wizard is provided with an interface panel to accept external inputs.
Can I use Climate Wizard to pre-cool the fresh air before it enters a refrigerated air conditioner?
Yes, We call that Cold Front Cooling. It is a very efficient way to provide cool fresh air to the indoor air circuit. Follow the link to find out more detail.
Can I install Climate Wizard on existing air conditioning systems?
Yes. Because Climate Wizard is a very efficient cooler in its own right, it can add to the cooling capacity of existing systems in a number of different ways. Follow the link to find out more detail.
How do I design for Cold Front Cooling?
First you must determine the amount of fresh air required and the design conditions for the site. From the tables in the application guide, the amount of cooling provided by Climate Wizard can be calculated. From this an estimate of energy saving can be prepared. Follow the link to find out more detail.
Can I use Climate Wizard in a new installation with refrigerated air conditioning as well?
Yes, the same principles apply regardless whether it is a new or old system. Where a new system is being installed, the Climate Wizard cooling capacity will reduce that needed to be provided by the refrigerated portion, with a resulting reduction in size, for the given total requirement. Follow the link to find out more detail.
Is there a limit to how many Climate Wizards can be installed with a refrigerated system?
The optimum proportion of Climate wizard depends upon the climatic conditions and the desire for energy savings. In most cases there are practical considerations around temperature and humidity control that guide the decision. Follow the link to find out more detail.
Can Climate Wizard work in conjunction with split systems?
Yes, this can be an ideal application as most split systems do not provide any fresh air. By adding Climate Wizard not only can it improve the energy consumption but the added bonus of fresh air is a huge advantage.
Can Climate Wizard accept return air from the building?
Yes, a portion of the return air can be returned to the Climate Wizard. This can be most beneficial in humid areas where Climate Wizard is applied as Cold Front Cooling. A full psychrometric analysis is recommended before this is undertaken. Follow the link to find out more detail.
How does Climate Wizard control the air temperature of the conditioned space?
Climate wizard is supplied with a sensitive wall control / thermostat. This senses the temperature and adjusts the fan speed to provide more or less cooling, proportional to the set temperature on the wall control. A building management system can also control the Climate Wizard. Follow the link to find out more detail.
Can you use existing ducting when changing from one system to another?
This depends upon the size and condition of the ducts. In any installation the intention should be to minimise the heat gain in the ducts. This usually means the ducts should be as small as possible and very well insulated. Follow the link to find out more detail.
Can I use bore water in Climate Wizard?
Climate Wizard has a sophisticated water management system that copes with harsh as well as relatively pure water. The more dissolved solids (salinity or hardness) in the water, the higher will be the usage. However, extremely harsh water, such as might be obtained from bores (or wells) in the outback (bad lands and deserts), could be deleterious to Climate Wizard. In these cases it is best to have the water sampled and to contact your Climate Wizard Dealer for advice.
What maintenance do I have to do?
The design and construction of Climate Wizard does not require frequent maintenance. We recommend that at the conclusion of the cooling season, the side access panels are removed for inspection and the condition of the filters and cores is checked. The owner’s manual has advice in regard to maintenance.
What do I do to winterize Climate Wizard?
The Owner’s Manual has instructions on what to do at the end of a cooling season and how to prepare for winter.
Does Climate Wizard need any additives to make it work?
No, definitely not. It's a good question because at least one other brand does require additives, but Climate Wizard will deliver cold air within a few minutes of being started.
Is Climate Wizard a complicated machine - are there many components that can go wrong?
Climate Wizard only has a fan, a pump and a couple of water system valves that have moving parts. It's really a simple machine. And it's designed and made by Australia's leading Air Conditioning manufacturer, who has a high reputation for reliability and has won many awards for innovation and quality products.
How is Climate Wizard controlled?
The cooler is supplied with a standard Wall Control that has an inbuilt thermostat. You can either use that control or you can connect the cooler to an external control system such as a Building Management System.
What sort of technical support does the manufacturer provide?
Seeley International and its dealer networks and distributors around the world provide technical support that is the envy of competitors. We want to partner with you as you take the Climate Wizard product on board and attempt to design it into your systems.
