Air conditioning, or HVAC&R, is an active, rapidly developing technology. It is closely related to the living standard of the people and to the outdoor environment, such as through ozone depletion and global warming.
Heating – Heat pump
One of the most promising technologies to reduce green house gas emissions is provided by electric heat pumps. Heat pumps offer an energy efficient way to provide space heating and preparation of sanitary hot water. The word heat pump is a collective term for a wide range of products utilising the same working principle. There are however many different types of heat pumps, all of which most suitable for different applications. Our experts are familiar with all the latest technologies on the market and our services are invaluable when it comes to selection and installation of the system.
All types of heat pumps have their own pros and cons as well as environmental impact. The most important aspects to consider during an evaluating of different heat sources are; availability, temperature level, annual temperature fluctuations and investment cost attributed to the choice of heat source. In reality the choice will be limited due to prevailing local conditions. We provide custom-tailored solutions that fit your specific situation which makes for optimal energy and cost savings on your part.
Our installers posses a mixture of skills, which are normally covered by different professions (electricians, plumbers and HVAC technicians). The overall efficiency of the system is very much dependent on accurate design of the heat source and proper integration with the heat distribution system and other auxiliary systems. The lack of qualified installer has been recognised as one of the greatest barriers on some of the emerging markets in Europe. From experience it is known that poor installation may have a dramatic negative effect on the market as a whole.
Ventilation
Air systems and their controls directly affect the indoor environment and indoor air quality. In a broad sense, air systems are a group of subsystems in an air conditioning system. Air systems inclued supply and return air systems (space recirculating systems), mechanical ventilation systems, air distribution systems, regenerative systems, smoke control systems, and terminals. The main functions of air systems are as follows:
Ventilation is an important part of building management. This has a major impact on the health of your employees and the subsequent production process. An important condition is that your ventilation system is well laid out and that there is regular maintenance. We advise, supply, install and maintain your ventilation and air purification systems.
We visualize the indoor climate of your data center, server and / or business space by means of a visual inspection and various measurements. The current laws and regulations are the central starting point for our advice.
Air Conditioning systems
The basic steps in the development and use of a large air conditioning system are the design, construction, commissioning, operation, energy efficiency upgrading, and maintenance. We can help you achieve your project results in every step of the way.
We also make sure that you have a well-designed and -maintained Building Management System for medium-size or large projects with generic controls in graphical display, monitoring, trending, totalization, scheduling, alarming, and numerous specific functional controls to perform HVAC&R operations in air, water, heating, and refrigeration systems. HVAC&R operations must be controlled because the load and outside weather vary.
Our goal is to provide an HVAC&R system which is environmentally friendlier, energy-efficient, and cost-effective as follows:
- Effectively control indoor environmental parameters, usually to keep temperature and humidity within required limits.
- Provide an adequate amount of outdoor ventilation air and an acceptable indoor air quality.
- Use energy-efficient equipment and HVAC&R systems.
- Minimize ozone depletion and the global warming effect.
- Select cost-effective components and systems.
- Ensure proper maintenance, easy after-hour access
Retrofit, Remodeling, and Replacement
Retrofit of an HVAC&R system must be tailored to the existing building and integrated with existing systems. Each retrofit project has a motivation which may be related to environment, safety and health, indoor environment, energy conservation, change of use, etc.
If you are not sure if your HVAC&R system needs to be replaced or converted there are some factors to take into consideration. For the sake of safety, smoke control systems and stairwell pressurization are items to be considered. For the sake of the occupants’ health, an increase in the amount of outdoor air may be the right choice. If energy conservation is the first priority, the following items are among the many that may be considered: efficiency of lighting; energy consumption of the fans, pumps, chillers, and boilers; insulation of the building envelope; and the remodeling or replacement of fenestration. For improving the thermal comfort of the occupant, an increase of the supply volume flow rate, an increase of cooling and heating capacity, and the installation of appropriate controls may be considered. Regardless of the the goal you set out to achieve, GCE-Group can guide you to the right solution.
