Consequently, almost any business or government agency has the potential to realize significant savings by improving its control of HVAC operations and improving the efficiency of the system it uses. Extended comfort includes employing concepts such as providing warmer, but drier air using desiccant dehumidification in summer, or cooler air with warmer windows and warmer walls in winter. In addition, high-performance HVAC can provide increased user thermal comfort , and contribute to improved indoor environmental quality IEQ. Given the range and complexity of the subject, this information should be viewed as only a starting point to access information from the many trade associations, agencies, and manufacturers linked throughout the text.

5 Advantages of Ductless Heating and Cooling Systems
Very little energy is needed to make a well-designed house comfortable. Appropriate insulation, which is essential for a comfortable house, combined with passive solar design and a draught-proofed building, can create low or even no energy requirements for heating and cooling see Passive solar heating; Insulation. Highly efficient homes with no heating or cooling input are possible across much of Australia. Even for existing homes there are many ways to reduce energy bills, improve comfort and help the environment. The principles of thermal comfort and the importance of air movement, humidity and radiant heat are explained in the section Passive design. Projected average home energy use in — actual energy use varies from state to state particularly with climate and from home to home depending on the heating and cooling systems in the home and how they are used.
Heating and cooling
Most people have heard of ductless heating and cooling systems, and they have probably seen the small, indoor devices installed high on walls in homes, restaurants or office buildings. But what do you really know about these systems? They are comprised of a small outdoor unit and one or more indoor units that require nothing more than mounting capabilities and access to electricity. Sometimes referred to as split systems, mini split systems, multi-split systems, or split-ductless systems , ductless heating and cooling offers home and business owners a cost-effective way to replace inefficient window air conditioning units, space heaters and electric baseboard heaters. They can be installed in home additions, new construction, condominiums and apartments, or to improve temperature control in specific rooms.SEE VIDEO BY TOPIC: How Air Handling Units work AHU working principle hvac ventilation

Heat pumps continue to represent a small share of total residential heating equipment, as more than three-quarters of sales globally were for fossil fuel or conventional electric technologies in Sweden, Estonia, Finland and Norway have the highest penetration rates, with more than 25 heat pumps sold per 1 households each year. Air-to-air heat pumping technologies dominate global sales for buildings, but purchases of other heat pump types such as air-to-water and geothermal heat pumps have also expanded in recent years. For example, sales of heat pump water heaters for sanitary hot water production have more than tripled since , largely driven by purchases in China.

Our absorption chillers use an innovative two-step evaporator and absorber cycle for better energy efficiency, reliability, and lower total cost of ownership.
Heating, ventilation, and air conditioning HVAC  is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering , based on the principles of thermodynamics , fluid mechanics and heat transfer. HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, vehicles such as cars, trains, airplanes, ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
Usually a sensing device is used to compare the actual state e. Then the control system draws a conclusion what action has to be taken e. Central controllers and most terminal unit controllers are programmable, meaning the direct digital control program code may be customized for the intended use. The program features include time schedules, setpoints , controllers, logic, timers, trend logs, and alarms.
