Chillers and energy savings

Our chillers draw less power than most of our competitors, while doing so they produce more BTUs. When you compare specs please notice the minimum breaker size and running load amps.

Lubinski February 1, Proper mechanical insulation of chilled-water piping is critical. The life-cycle cost savings and risk avoidance made possible by insulating chilled-water piping is vital to the design of a high-functioning system.

Chilled-water pipe insulation is the wrong place to attempt value engineering when designing new or replacement piping. These mistakes can also create a liability for future chilled-water pipe replacement; in the worst-case scenario, this can even lead to a catastrophic failure of a system that will damage a building and possibly even affect its occupants.

The selection of the correct pipe insulation can be critical to energy consumption and potential piping damage, especially in higher humidity areas near major bodies of water. What works in the dry desert southwest obviously will not work in major cities close to the oceans, lakes, and major rivers.

If you look at the U. Mother Nature does not like differences in temperature, pressure, or humidity. Therefore, you can expect natural flow from an area of high humidity toward an area of low humidity. This effect is magnified if there is also a flow from medium temperature to extremely low temperature i.

If the wrong insulation product is used, it can become wet due to condensation. Once wet, the insulation will lose its insulation value, waste energy, and must be removed.

The problem gets worse as wet insulation is held against steel pipe. Due to gravity, the maximum insulation wetness tends to be on the bottom of the pipe. Observing ondensation leaking from insulation, or wet insulation, is a symptom of a major problem below the surface of the insulation.

Incorrect installation creates the opportunity for condensation problems to start as soon as the insulation is installed, especially at the insulation joints. Thousands, if not millions, of pipes and valves, are left uninsulated in many buildings.

If a mechanical contractor fails to hire a professional insulation subcontractor, then the installation is often incomplete. End-user building engineers often focus on replacement chillers, or domestic water-heating systems, and therefore overlook the issue of uninsulated pipes for chilled water, domestic water heating, steam piping, etc.

Water is a superior product for transmitting heat or cold, and transfers BTUs several times faster than air. Some engineering studies have shown that water will transmit heat or cold 10 to 30 times faster than room air.

While water is a great delivery vehicle for heating and cooling buildings, it is often utilized based on the assumption that it is transported in properly insulated pipes. If any one of these steps is not followed, then one cannot expect the HVAC system and its pipes to perform as expected over the life of the building.

Since central HVAC systems are expected to perform for 20, 30, 40, and even 50 years, it becomes critical that the chilled-water pipe installation is properly selected, installed, and maintained.

Infrared cameras are useful tools to look for heat loss and to identify thermal differences due to wet insulation. Infrared camera fly-overs are sometimes used to find leaking underground pipes. Infrared cameras can show images in infrared, black-and-white, or combined combined is referred to as fusion wet insulation in roofs and pipe insulation.

Advanced infrared camera software can also show the temperatures of the pipe and equipment photographed for inclusion in reports and recommendations.3 Improving industrial productivity energy savers through energy-efficient advancements BUYING TIPS Buyers must decide between air-cooled or water-cooled systems eliminate the need for a cooling tower which reduces installation and O&M costs.

Heat Recovery Chillers ECONOMIC AND ENVIRONMENTALLY-RESPONSIBLE ENERGY SAVINGS Whether striving to minimize the operating costs of a facility or reducing the building’s carbon footprint, heat recovery from the chilled water system is entirely possible and practical.
