How does a natural gas air conditioner operate? Natural gas is burned to heat a water and ammonia mixture, evaporating the ammonia from the water and condensing it outside the home. This ammonia is then decompressed and evaporated around a circulating water system, cooling the water. The water circulates through piping and thus cools the home. What is an Aquatherm heating system? What is a compressor's function on an air conditioner? Most natural-gas-powered air conditioning units for homes are classified as small, direct-fired absorption chillers and use ammonia and water as components. Both these components are environmentally safe. These units use ammonia as the refrigerant while water is the absorbent. In general, absorption units work through the condensation of the refrigerant, which removes heat from the absorbent. This method of air conditioning is perfect for homes with baseboard heating, and does not require duct work to operate. The whole unit works in a cycle, with the beginning and end products of the reaction both being a mixture of ammonia and water.

Initially, the mixture is heated by natural gas and ammonia condenses outside the home in a coil. The ammonia then cools a circulating water system through evaporation at a low pressure. This water system circulates through the home and cools it. After the ammonia evaporates, it is reabsorbed into the water source and then process repeats over again. An HVAC gas pack is a heating and cooling system with the heat pump and the air conditioner housed together in a single unit. HVAC gas packs use propane, n...

What are some highly rated pellet stoves according to experts? Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas (in a process called phase conversion), it absorbs heat. Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils.

The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils. When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils called condenser coils, and a second fan. As the gas cools, it changes back to a liquid, and the process starts all over again. Think of it as an endless, elegant cycle: liquid refrigerant, phase conversion to a gas/ heat absorption, compression and phase transition back to a liquid again.

It's easy to see that there are two distinct things going on in an air conditioner. Refrigerant is chilling the indoor air, and the resulting gas is being continually compressed and cooled for conversion back to a liquid again. On the next page, we'll look at how the different parts of an air conditioner work to make all that possible. Yanmar’s Gas Powered Air Conditioners are multi-split systems, with one outdoor unit connected to a number of indoor units. inside ac unit fan not workingIn traditional electric multi-split systems, the compressors in the outdoor unit are powered by electric motors, but in the Yanmar system a small gas engine drives the compressors. heat pump unit for saleIn traditional electric systems, the electric motors change speed to match the varying heating or cooling requirement of the building. can window ac unit make you sick

In the Yanmar system, the engine automatically changes speed to achieve the same result. These outdoor units are sometimes referred to as Gas Heat Pumps or GHPs.Yanmar have been building engines in Japan for over 100 years and they have developed a special range of gas engines to power these air conditioners. These are spark ignition piston engines (similar to a small car engine) and have been designed for low noise, long life and minimal maintenance. They only need servicing every 10,000 hours or 5 years.All the indoor components (ducted units, ceiling cassettes, wall mounted units, remote controllers etc.) are similar to that used by traditional electric multi-split systems, so the whole system looks and feels very familiar to users. Yanmar was one of the first manufacturers to develop gas engine driven air conditioners in Japan around 25 years ago and has been a market leader ever since. The Japanese government encouraged the development of these systems in the 1980s as a means to reduce the peak load on Japan’s electricity networks, a significant issue facing Australia’s energy industry today.

Yanmar’s Gas Powered Air Conditioners have been sold in Australia and the South Pacific since 2008 and there are now hundreds of systems installed throughout the region. As the Distributor for this region, Yanmar Energy Australia has a team of qualified technicians to support the product and stocks all of the spare parts recommended by Yanmar. Using a gas engine to drive the air conditioning compressors reduces the electricity required byaround 90%. In many new building projects and building refurbishments, there is not enoughpower available to operate electric reverse cycle air conditioners, so money must be spent onupgrading the electrical services. These large costs can be avoided by installing gas powered airconditioning.For example, many school buildings were constructed 30 or 40 years ago. The power supply was adequate at the time, but these days classrooms need power for laptop computers, electronic whiteboards etc. If the school requires reverse cycle air conditioners for the classrooms, the original electrical supply may not cope.
