Cooling Tower Online

Energy saving without sacrificing efficiency is crucial when you plan to replace absorption type of chiller with a chiller that is mechanically driven. Chillers that are mechanically driven let you save the amount of water needed to evaporate heat. You can save as much as 40% to 55% of the required amount of water needed for the evaporation process inside the cooling towers when you replace your absorption chiller with an electric rotary screw or a centrifugal chiller. You can tell the difference later when you see your water consumption bill and all cost associated with it as well as your sewer charges. An inefficient water-cooled chiller wastes about 15,400 Btuh while the highly efficient ones wastes only 13, 500 Btuh per ton of cooling produced. A water-cooled chiller with McQuay heating coils typically operates at given flow rate and at desired temperature to meet given building load requirement. You can lower your unit’s energy consumption and electrical demand using ice or chilled water during peak time to offset peak loads.

Tankless McQuay heating coils are indirect water heaters usually applied as residential space heating system for heating water. The McQuay heating coils are part of the recent technology about combined space and water heating system. The tankless coil uses a McQuay heating coil in the main furnace or boiler. The water passes through the McQuay heating coil when you turn on the hot faucet. However, tankless coil proves to be more efficient during cold season when you use your heating system because they rely on the furnace for directly heating the water. Indirect water heaters save more energy because they utilize the heat generated by the furnace and minimize turning on and off the furnace. The well-insulated storage tank and high efficiency furnace are two of the most cost effective approach to providing hot water.

Replacing your current cooling and heating system requires accurate selection of the new system’s efficiency rates. If you want to upgrade your heating and cooling system, you need to consider first the limitations of your current system, which greatly affects limitations on your choices. Thermostats, McQuay heating coil efficiency, and ducts provide wonderful opportunities for you to save energy consumption. The pressure drop difference between the McQuay heating coil and the air or water flow arrangement is crucial for unit design optimization. Contact your McQuay heating coil agent and ask for the right unit specifications that will meet your requirements.

When the days get longer and the thermometer starts to climb, there is only one thing on most people’s minds, besides bikinis. We are talking, of course, about air conditioning. Like most modern appliances that make our lives easier and more comfortable, air conditioners are something we tend to take for granted.

In this article we are going to take a much closer look at these invaluable machines. We will be paying particularly close attention to how they operate.

Types of Air Conditioners

As you may know, air conditioners are available in various sizes, cooling capacities and prices. Probably the most common kind is the standard window air conditioner. These models are often easy to install, but their cooling power is somewhat limited and so is their overall efficiency.

On the other hand, window air conditioners are still the best way to cool a small space, like a studio or a one bedroom apartment. That is you see them sticking out of the windows of most small apartments.

While window air conditioning units are primarily urban machines, when you pass through the suburbs you will likely find a different kind of cooling device. These are called condenser units, and they are used to run a central cooling system. They are often installed in the backyard and they are far more efficient and thus more inexpensive than window units.

Condensing units are also used to cool most businesses and office buildings. However, instead of installing them in the backyard, there will often be banks of condenser up on the roof.

The final type of air conditioning unit is a cooling tower, which is often only used at enormous office complexes or colleges. These towers are connected to the in house air conditioning system and greatly improve their power and efficiency.

How They Work

In spite of the differences in size and power, all air conditioners follow the same basic rules of operation. And contrary to popular belief, they do not simply pump cool air into your home, office or apartment. What is actually happening is that warm indoor air is removed, cycled and returned as cooler air. This process continues until the room or home reaches the right temperature.

If you need a reference, an air conditioner is really nothing more than a refrigerator without the room to store your food. It relies on the evaporation of common refrigerants, like Freon, to cool warm air. A refrigerator does exactly the same, except, of course, it is used to cool food.

But how does air conditioning actually work? First, the compressor inside the machine compresses cool Freon gas, which causes it to get hot and increases the pressure. The hot gas then passes through a series of coils in an attempt to reduce heat, and afterwards, it condenses into a liquid. The liquid then moves through a special valve where it evaporates and becomes extremely cold Freon gas. Finally, this cold gas moves through another series of coils and in the process it absorbs the indoor heat and cools down the room.

The advent of air conditioning has brought countless benefits to the world; human comfort being probably the main benefit we think of whenever we talk about air conditioning. The hot summer season spells inconvenience and a lot of sweat at work and at home without air conditioning. On the other hand, the coming of winter signifies torment with the unbearably frigid temperatures that come along with it if one is without air conditioning.

Most office buildings and industrial plants in most countries of the world have air conditioning facilities installed to provide good working environment for their work forces. In temperate countries, modern premises are well equipped with sufficient air conditioning systems to cool both workers and products, especially when the temperature is high all year round.

An office air conditioning system can provide full control of temperature, dust, humidity and air distribution unlike most home cooling systems. Basically, an office air conditioner resembles a room air conditioner where a refrigerant passes through a cooling coil and refrigeration occurs in a separate unit. Multi-storey office buildings on the other hand require larger units and use water-cooled condensers since air-cooled condensers are often not available. A separate cooling tower is usually included in water-cooled condensers in order to conserve water. The condenser water in the cooling tower is cooled by evaporation into the outside air. Sometimes offices have different temperature requirements for different sections. In cases where different sections demand varying temperature settings, two air ducts are used. One duct carries cool air while the other duct carries warm air. Upon entering a space, air is then mixed to the desired temperature as indicated by the thermostat setting. Since space is valuable in any office building, all possibilities are exhausted in order to save this. That’s why duct systems with significantly much higher air velocity and air pressure compared with those used in home systems are being used specifically for office air conditioning.

Today’s modern school buildings have been provided with cooling equipment as well. Some building designs expose the indoor environment to the heat of the sun especially during the summer season. There are many one-storey schools with huge east and west glass walls and a lot of solar exposure through the roof and windows. These types of buildings necessitate the use of air conditioning units for effective teaching and learning, especially during the hot and humid months of summer. Studies show that there is a correlation between the use of air conditioning and the significant decline in absenteeism during the hot summer days. There is also inconclusive evidence that points to the decrease in respiratory ailments where air conditioning is used in offices and schools.

Air conditioning, whether to provide cool air during hot weather or warm air during cold weather, has proven to be one of the most valuable discoveries of our time. It has provided us with comfort and ease in our daily lives. Those who work in offices and teachers and students in schools can concentrate on their respective tasks because of the comfort that air conditioning provides. Can you imagine working in your office without it? You might just freak out!
