Custom air conditioning systems for green building – energy efficiency systems

Custom air conditioning systems for green building – energy efficiency systems

Green building is a system-wide approach to planning, construction and operation of buildings, followed in the early design stage through to current operations, in accordance with the principles of environmental protection and saving energy and water.

The area of commercial air conditioning has major importance as a central issue in green building construction. CSK Climatek, the Temperature & Humidity Solutions division of CSK Group, specialise in planning air conditioning systems adjusted for low energy consumption, adapted to the needs of green construction and its demands. To get to minimum energy consumption and answer the needs of the green construction (following the Australian standard) there is a use of advanced technological elements:

Variable Refrigerant Flow

Variable refrigerant flow including central condense units among them invert compressors changing their output following to the energy consumption needed using internal units and therefor reduces significantly the energy consumption. The condensation units provide refrigeration (cool gas) in changing flow for number of internal air conditioners. Such as CSK Group commercial air conditioning, the refrigeration flow is set by controlled valves to achieve precise temperature while consuming minimum energy.

Heat Recovery

Central systems for the production of cold water with a dedicated heat recovery system, that heating water by using the hot gas line as early condenser and or as a substitute. The result of the use in technology is creating free hot water, as a by-product of the cooling system without extra cost. Another level in this technology is Cool Recovery allowing receiving free hot water while using units working as Heat Pumps to make hot water.

High Efficiency

Using water cooling units are defined as units adjusted to the predict consumption profile of the facility, means units with high COP (Coefficient Performance) which is used for measuring the efficiency of the water cooling systems at the planned flow and the planed work conditions. Choosing cooling unit with high COP allows efficiency at the work of the unit in maximum output and/or units with high IPLV (Integrated Part Load Value) or ESEER (European Seasonal Energy Efficiency Ratio). Both COPs are reliable measurement for the efficiency of the cooling units in percentage of partial load, means – changing outputs, allowing the get energetic efficiency in changing loads and changing outdoor temperatures.

Variable Refrigerant Flow

Variable refrigerant flow including central condense units among them invert compressors changing their output following to the energy consumption needed using internal units, therefor reduces significantly the energy consumption. The condensation units provide refrigeration (cool gas) in changing flow for number of internal air conditioners. Such as CSK Group commercial air conditioning, the refrigeration flow is set by controlled valves, to achieve precise temperature while consuming minimum energy.

Central systems to make cool or hot water

By using cooling/heating water units, with condense water or air and supply them using a system of water pumps and isolated water pipes.

Direct spread of refrigeration

Direct spread of refrigeration to large open spaces like sports halls for example.

Variable air volume

System based on units looking after air that supply air in variable flow as a function measured in the channels, that for providing different temperatures in different rooms. The control units in the various rooms control the flow supplied to each room.

Systems based on specific unit for fresh air

Split air conditioners and or inverter air conditioners.

Design air conditioning systems in commercial, industrial, public and residential buildings

During the planning control, sophisticated efficient systems are integrated, allow complete control and the CSK Group commercial air conditioning facilities, while saving energy and troubleshoot malfunctions in advance.

Installing air conditioning systems

Over 7 years of operation CSK Climatek, and division of CSK Group, involved in hundreds of variety of projects in commercial, industrial, public and residential buildings installing air conditioning systems including:

Shopping centres and malls
Major energy centres for air conditioning

Corridor weighting systems getaway and escape stairs
Schools and educational institutions

Unique Air Conditioning Solutions

Each project and with each client CSK Group match unique solution, designed to meet specifically the developer or the client’s requests, providing complete, full response to demands, needs and budget.

Installing air conditioners

Installing air conditioning guide

Installing air conditioning is a complex which required quality, careful and professional work. The best quality air conditioning system will not work if it wasn’t installed properly, therefor there is a need to look after quality installation using proper air conditioning installation Brisbane (CSK Group) company.
Installing air conditioning isn’t a simple task, and there are many considerations and decisions to look into:

Power supply

Air conditioners are power consumers and the building’s electric panel must be adjusted for this. Many times there is a need to add or remove parts at the panel, and sometimes also to increase the power supply to the building. Such action needed to be done only by professionals whom are certified to do so and in coordination with the power company. Near the place of the installation of each cooling unit must be installed a suitable power point, if using existing electrical pipes and if the transfer of additional external line. The job must be done by a qualified electrician.

Installing the cooling unit

In the event of normal upper air conditioning install, the cooling unit isn’t very heavy and its installation is relatively simple – drilling few holes in the wall and hanging the unit using suitable screws. In the case of central air conditioner installation it is much more difficult. The project involves lowering the ceiling using plaster, hanging the central unit, transferring cooling channels to the rest of the building while building transitions to fit and creating openings suitable for walls, closing all ceilings and passages with sheet metals or plaster and finally a skid and paint – great complicated job.
