CSA C368.1-14:2019 pdf download.Energy performance of room air conditioners
5.2.1 General
The method for testing room air conditioners in standby and off modes shall consist of application of the methods and conditions in CAN/CSA-C62301, as modified by the requirements of this Standard. The testing may be conducted in test facilities used for testing cooling performance. If testing is not conducted in such a facility, the test facility shall comply with Clause 4.2 of CAN/CSA-C62301.
5.2.2 Test room conditions
The indoor test conditions as required by Clause 4.2 of CAN/CSA-C62301 shall be maintained. If the standby and off mode testing is conducted in a facility that is also used for testing cooling performance,the outdoor test conditions either as required by Clause 4.2 of CAN/CSA-C62301 or as standard rating condition shall be maintained. If the unit is equipped with an outdoor air ventilation damper, this damper shall be closed during testing.
5.2.3 Power supply
Power supply conditions specified in Clause 4.3.1 of CAN/CSA-C62301 shall be maintained. Room air conditioner nameplate voltage and frequency as the basis for power supply conditions shall be used. Power supply voltage waveform in accordance with the requirements of Clause 4.3.2 of CAN/CSA-C62301 shall be maintained.
5.2.4 Watt meter
The watt meter used to measure standby mode and off mode power consumption of the room air conditioner shall have the resolution specified in Clause 4.4 of CAN/CSA-C62301. The watt meter shall also be able to record a“true" average power specified in Clause 5.3.3 of CAN/CSA-C62301.
6.2.2 During the entire evaporator air blockage, frost or ice shall not form on the cooling coil to the point where icing could progress to cause the air flow to be cut off.
Note: The specified temperature conditions and test duration are a guide for establishing minimum performance at low outside ambient temperature, which in turn should meet reasonable expectations of product performance. The recommended maximum ice accumulation is based on industry experience that 50% free area of the evaporator coil will permit the unit to clear itself as temperatures rise.
6.2.3 During the defrosting period after the completion of the drip test, all ice or melt water shall be caught and removed by the drain provisions.
Note: Good engineering practice and long-term field experience dictate that the unit should not discharge ice and condensate on the room side, which could cause water damage to property and/or create extraneous electrical hazards. The test criteria and the recommended level of performance are based on experience and are believed necessary to meet reasonable expectations of product performance.
6.3 Enclosure sweat
Room air conditioners shall pass the test prescribed in Clause 7.1.5. During the test no sweat shall drip,run, or blow off from the indoor side of the enclosure.
Note: Although it is unusual for the room side to remain at 80% RH for 4 h in actual application, field experience has shown that conformance with the test procedure and recommended level of performance tends to assure product satisfaction. The recommended level of performance is based on experience and is believed necessary to meet reasonable product expectations and to prevent problems associated with room-side water discharge (see Note under Clause 6.2.3) as well as problems associated with outside water discharge, such as slippery sidewalks and water staining of the outside structure.CSA C368.1-14 pdf download.
