After the refrigerant condenses to a liquid, it passes through a device to reduce pressure.  It can be a simple orifice plate or an electronic modulating valve.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.

Optimize building loads by using more than one chiller. Use the most efficient chiller first.  Increase the supplied chilled water temperature and establish a reset schedule to change the water temperature as the ambient air temperature changes.  On a centrifugal chiller, increasing the temperature of chilled water supply by around 2°F will reduce chiller energy use by up to 5%.

Training workers in proper operations and maintenance is key. Enforcing routines is the most successful approach. Out of compliance operations are often unnoticed until it is too late. Regular safety and operations training is the best way to protect an HVAC system.

Graduates convey ideas and information effectively to a range of audiences for a variety of purposes and contribute in a positive and collaborative manner to achieving common goals.

Air trapped in the refrigerant loop increases compressor exit pressure and increases the work required from the compressor. Modern chillers run-time meters and automatic air purgers. Regular tracking of run time shows if a leak permits air to enter the system.

An evaporator in a centrifugal water-cooled chiller is the heat exchanger that removes heat from the entering chilled water. A shell and tube heat exchanger is the most common configuration.

Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.

A centrifugal chiller uses the vapor compression cycle to chill water. It throws off the heat collected from the chilled water plus the heat from the compressor to a water loop. The water loop is cooled by a cooling tower.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

If your system has a water-side economizer, use it during the cold season. Condenser water circulates through the cooling tower to push heat into the atmosphere. The water is cooled sufficiently to meet the cooling loads.

Decrease the condenser water temperature. A temperature reduction of around 3°F in the cooling tower water returned to the condenser reduces energy consumption by nearly 3%.

The setpoint for water leaving the cooling tower should be as low as the manufacturer will allow for water entering the condenser.

This part is in stock and available for purchase online along with many other Gordon Piatt Burner Replacement Parts.

Regular preventive maintenance helps maintain operational time.  A combination of good operational practice and maintenance limits downtime. An annual or more often inspection prevents damage.

For peak chiller efficiency, check the refrigerant level and temperature readings. Compare them to the manufacturer's operational recommendations. Correct anomalies promptly.

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

The University's policy on Assessment for Coursework Programs is based on the following four principles: Assessment must encourage and reinforce learning. Assessment must enable robust and fair judgements about student performance. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned. Assessment must maintain academic standards.

Commercial HVAC systems use 19% of the total U.S. energy. 39% of a commercial building's energy consumption is dedicated to air conditioning and heating. Keeping air conditioning system components like your centrifugal chillers in tiptop shape for the highest efficiency, is the challenge for many businesses.

Graduates are responsible and effective global citizens whose personal values and practices are consistent with their roles as responsible members of society.

The heat raises the temperature of circulating condenser water  The condenser water then carries the heat away to the cooling tower where the excess heat is ejected to the atmosphere.

A high-performance commercial HVAC system uses some sort of chiller to carry heat out of the interior circulating air. In some areas, water or air alone is sufficient to remove excess heat. Most HVAC systems depend on some sort of compressor system to move a heat-absorbing refrigerant around a coil.

A centrifugal compressor converts rotational kinetic energy to the dynamic energy of fluid flow. Refrigerant enters the pump impeller and is accelerated, flowing radially outward, then exits. A frictionless centrifugal compressor uses magnetic bearing technology and a DC (direct current) motor drive.

Similar to an evaporator, a condenser is also typically a shell and tube heat exchanger. The condenser removes heat from the refrigerant gas. The pressurized refrigerant condenses to a liquid.

The heat changes the refrigerant from a liquid to a gas. A flooded evaporator is an energy-efficient choice. Chilled water circulates in the tubes and refrigerant completely submerges the tubes in the shell.

Your vehicle has many components that rub together and create an incredible amount of friction. As you know, when there's friction, there's heat.

An annual inspection by a professional keeps your HVAC in its best condition. Look for a professional with expertise with your type of system. More frequent inspections by on-site personnel supplements professional service.

Graduates engage in professional behaviour and have the potential to be entrepreneurial and take leadership roles in their chosen occupations or careers and communities.

In areas where hard water is a problem, water treatment is a must. Without intervention, scale, and sediment build-up and reduce efficiency. At worst, the extra work can burn out your pumps and motors entirely.

Graduates have comprehensive knowledge and understanding of their subject area, the ability to engage with different traditions of thought, and the ability to apply their knowledge in practice including in multi-disciplinary or multi-professional contexts.

Centrifugal chillers are popular because they have relatively few moving parts. They are easy to maintain and long-lived. Centrifugal chillers provide high cooling capacity with a small footprint.

Graduates are effective problems-solvers, able to apply critical, creative and evidence-based thinking to conceive innovative responses to future challenges.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

Since 1902, air conditioning has made life inside more comfortable. There are few modern commercial buildings lacking air conditioning in the U.S. The modern air conditioning system is what makes it possible to sit through a movie during the summer in comfort or produce chocolate truffles in 100F weather.

Graduates are self-aware and reflective; they are flexible and resilient and have the capacity to accept and give constructive feedback; they act with integrity and take responsibility for their actions.
