COMPETITION DETAILS - MODULE A

COMPONENT FABRICATION

MAXIMUM TIME ALLOWED - 3 HOURS 13.5 MARKS

SCOPE The Competitors are required to fabricate a copper tubing circuit for the secondary refrigerant circuit that will form the ice rink surface, this coil will be incorporated into the design of the system at a later stage. The coil is constructed using 13 lengths of 1/2” copper tubing, fed by a 7/8” copper header as per supplied drawing. This entire unit will sit in the bottom of a tank and form the secondary refrigerant coil for the ice rink being installed in Module B.

TIMING Competitors are to all complete the ice rink piping at the same time in the morning of C1, this will allow for marking to take place in the afternoon, any Competitors that do not finish Module A in the allocated time will be required to submit the unfinished project for assessment. Competitors will receive additional points for completing this module in less than the allocated time (as defined in the marking summary) providing that the fabricated component does not leak when pressure tested.

ASSESSMENT Competitors will be assessed as per technical description, the marking scale will reflect dimensions and tolerances for assessment in addition to the quality of brazed joints. Fabricated component will be tested for leaks by pressure testing with dry nitrogen to ensure no leaks are present. Any Competitor who does not complete Module A in the required time (3 hours) will be allowed to complete it after it is assessed and handed back to them during Module B – no additional time will be allowed for either Module A or Module B for those who do not complete the fabrication in the allotted time.

COMPONENTS Components to be installed will include the following;

• Pre manufactured 7/8” header copper pipework

COMPETITION DETAILS - MODULE B

REFRIGERATION SYSTEM INSTALLATION AND COMMISSIONING


SCOPE Competitors are to install a refrigeration system to refrigerate a small scale ice rink, the system uses a secondary refrigerant to remove heat from the ice rink and mimics a small industrial plant commonly used to carry out a much larger duty.

The Competitors are required to use the supplied components along with the coil fabricated in Module A to form a low pressure flooded system that utilizes a brazed plate heat exchanger to refrigerate propylene glycol to remove heat from water to form the ice rink. A small condensing unit is used to draw vapour off the top of the vessel and compress and condense the refrigerant, an electric expansion valve is used to meter the refrigerant into the vessel. Two level switches are used to control the liquid level inside the vessel, a capacity control valve is used to ensure suction pressure does not drop below design. Refrigerant is R134a.

Secondary refrigerant circuit for ice rink is to be constructed using copper pipe, copper pipe will be used to form the secondary refrigerant pipe circuit joining heat exchanger, ice rink coil and glycol tank with a flexible hose connection used to connect the copper pipe to the circulating pump.

Competitors are required to connect all components to a prewired electrical panel

TIMING Competitors are to all complete the installation over C1, C2 and C3. The secondary refrigerant circuit (glycol) pipework must be completed by the end of C2 for assessment overnight, the entire installation will be completed by the end of C3 for assessment. The completed project with ice rink frozen may be left running and displayed on C4.

ASSESSMENT Competitors will be assessed as per technical description with particular weighting on the commissioning and operation of the project.
