CHILLERS
A Chiller is a big version of air-conditioning system or central air-conditioning system and modern air conditioning was invented by an American Engineer named Dr Willis Haviland Carrier in 1902. He is also known as father of air conditioning.
As specialized advancement or invention typically can't be pinpointed to a solitary moment. Buffalo Forge where Willis Haviland Carrier used to work had made the Carrier Air Conditioning Organization as a division of Buffalo Forge. At the flare-up of World War I, Buffalo Forge settled on the business choice to no more seek after the new cooling business sector. The group left and structured the Carrier Engineering Corporation of America. The group includes Willis Haviland Carrier, L.L. Lewis, L.I. Lisle, and E.T. Murphy.E.P. Heckel,E.T. Lyle, and A.E. Stacey Jr. This group came up with many HVAC engineering development what we are using today and also this group of engineers invented the basic centrifugal chillers. Thus, Carrier Air Conditioning became the first industry in the field of Air Conditioning
The term chiller is used to describe the complete chilling package that includes the compressor condenser, evaporator, internal piping and other controls. A chiller is a machine that the heat of a fluid by vapor compression or absorption refrigeration cycle. This fluid can then be circled through a high temperature exchanger to cool air or gear as needed. As a vital repercussion, refrigeration makes waste hotness that must be depleted to encompassing or, for more excellent effectiveness, recuperated for warming purposes. Concerns in configuration and choice of chillers incorporate execution, effectiveness, support, and item life cycle ecological effect.

Most of the chillers works on vapor compression refrigeration cycle this can be replaced by Solar vapor absorption chillers which might results in many advantages over vapor compression chillers such as reduction in overall electrical cost, low noise operation, reduce operation cost, low co2 emission .
In Solar absorption chillers solar collectors has been identified as one of the promising form of renewable energy to improve the energy efficiency of the building which is needed as per present situation to reduce electrical consumption and to save electrical energy and reduce emission of co2.Extensive research is required to develop an economical building solar energy to meet the energy demand.

The first application I’m going to discuss where water is used as a natural refrigerant is a swamp cooler, with a swamp cooler there is a drum that is made of an absorbing material where the bottom of the drum is submerged in water. A fan blows outside air across the drum as the air passes over the drum the temperature of the air decreases as the relative humidity is drawn from the drum into the outside air that is passing across the drum. Some pros to using a swamp cooler are the pretty cheap to build and surprisingly quite efficient to run and maintain.” They're cheap to build and install. The only materials it takes to make them are a blower fan, a pump, a pad (either synthetic or made of wood shavings), some water and a box (usually made of sheet metal), The National Association of Home Builders (NAHB) estimates that an evaporative cooler, installed, costs between $700 and $1,000, compared to several thousand dollars for a central air conditioner (Swamp)” Although there are some pros to a swamp cooler if you live in a humid climate where some of the humidity needs to be r...
An Investigation Into How the Thickness of Insulation Affects the Time a Drink Takes to Cool Down
For most of history, ice and snow, packed into cellars insulated with wood or straw, were used for refrigeration. It wasn’t until 1755 that the first artificial refrigeration system was established by William Cullen (Koelet, 1992). Throughout the 1800s, many mechanical refrigeration systems were designed and developed, and the vapour compression cycle most commonly used today dates back to this time.
Standard Air Conditioner There are a number of standard air conditioner systems that are available on the market. One is a unitary system. The one room air conditioners sit in a window or wall opening, with interior controls. A large house or building may have several units, permitting each room to be cooled separately. Another type is the basic central air conditioning unit, which offers whole house-house cooling. It is usually a large, loud, mechanism that sits outside of the home. Although these standard air conditioners may be effective, they come with drawbacks. According to the U.S. Department of Energy, Americans spend $22 billion a year and use more than 183 billion kilowatt-hours of electricity to cool their homes with standard air conditioning. Also those air conditioners release about 100 million tons of carbon dioxide into the air annually -- two tons for each home that has one.
In warmer climates such as Egypt they used techniques as evaporative cooling, “if water is placed in shallow trays during the cool tropical nights, its rapid evaporation can cause ice to form in the trays, even if the air does not fall below freezing temperatures”. Although refrigeration developed in the 18th century it wasn’t until the mid-19th century when the first refrigerator built using vapor technology was build by American John Gorrie in 1844. A few years later commercial refrigeration was introduced as well as vapor compression technology which was the beginning of our modern refrigeration. Later that century ammonia was popularized as the evaporation chemical in refrigeration. All the trials and tribulations of refrigeration where all stepping stones to the 20th century and the introduction of modern refrigeration as we know it
Mechanical based heat pumps systems all have some common components: a compresser, a condenser, and an evaporator. The whole system is made of pipes that circulate a fluid that allows the transfer of heat. The evaporator is what transfer heat from the air in the room to the fluid inside of the system of pipes. The condenser is what takes the heat from the fluid and transfers it to the air outside.
Climate controlled storage units protect your belongings from extreme heat or cold. In addition to maintaining a consistent, comfortable temperature. The storage units also regulate humidity. This protects your belongings for a greater length of time and frees you from worrying that the weather will destroy your precious memories and valuable possessions.
An air compressor is a device that converts mechanical or electrical power into potential energy stored in pressurized air compressor. By one of several methods an air compressor forces more and more air into the storage tank and increasing the pressure. When tank pressure reaches its limit the air compressor shuts off. The compressed air is then held in the tank until called for use. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes.
In thermodynamics Refrigeration is the major application area, in which the heat is transferred from a lower temperature region to a higher temperature region. The devices which produce refrigeration are known as Refrigerators and the cycle on which it operates are called refrigeration cycles. Vapour compression refrigeration cycle is the most regularly used refrigeration cycle in which the refrigerant is alternately vaporized and condensed and in the vapor phase it is compressed. Gas refrigeration cycle is the well-known refrigeration cycle in which cycle refrigerant remains in the gaseous phase throughout the cycle. Cascade refrigeration are the other refrigeration cycles discussed in this chapter; absorption refrigeration is the one more refrigeration cycle which is used where the refrigerant is dissolved in liquid before it is compressed. One more refrigeration in which refrigeration is produced by passing the electric current through two dissimilar materials is called as the thermoelectric refrigeration.
Willis Haviland Carrier invented the first air conditioner in 1902. This was designed to boost the working process control in a printing plant. Carrier’s invention controlled temperature and humidity. The low heat and humidity helped keep the paper dimensions and ink alignment the same. Later his invention was used to populate productivity in the workplace. The Carrier Air Conditioning Company of America developed for the increasing demands. Gradually, air conditioning was used to help increase comfort in homes and cars. Residential sales increased rapidly in the 1950's.
Willis Carrier invented the air conditioner which keeps us cool. Do you know what the name of the first air conditioner was? Or where it was located? Willis Carrier came from a family who fixed things. Later in his life, he started his own air conditioner company. Willis Carrier’s life invention of the air conditioner keeps us cool when things get hot.
Solar thermal energy is dead! A solar thermal heating system can cost upwards of $7,000 to install and it most likely won't even save you too much money. This is why many people debate over whether they should use a solar thermal water heating system, because they think they are saving money, or an inexpensive traditional water heating system. A traditional heating system is a system that is powered off of electricity, gas, oil or some other fuel. A solar thermal heating system uses the energy from the sun, hence “solar”, and it turns that energy into hot water to either heat a home or to provide domestic hot water. The energy from the sun is captured by energy collectors, also known as solar panels. The water is heated inside the panels and then distributed throughout the home for use or stored in a tank for later use. The ideas behind this sound great, but in reality that is not the case.Solar thermal energy is not the best choice for home heating a home or hot water heating.
Before 20th century, most efforts were ineffective and people tried many things to provide the comfort of cool, till Leonardo Da Vince designed a mechanical fan and it was used in industrial settings. Then, an engineer named Stuart Cramer, he likes the idea of the latest system of controlling the heat and humidity and he improved it and called it “air conditioning” in 1906. One year later, air-conditioning equipment designed by Witten Meier was installed in movie theatres and hotels. And in 1927, General Electric introduces the first refrigerator to be mass-produced with a completely sealed refrigerating system and it was one of a kind. In 1927, these improvements continued to progress and engineers completed doing researches and they developed air-conditioning and refrigerating to consume a less amount of energy.
Solar water heaters work by using energy from the sun. There are two types of systems for solar water heaters, an open system and a closed system (“Tapping into the Sun”). These systems depend on the type of climates they are installed in (“Tapping into the Sun”). Open systems are worth the installation if the weather is year round sunny, closed systems are better if the weather gets cold. The water cannot be run during winter so the system will be switched to fuel and in the summertime when it is warm, so the sy...
