Air ConditioningPackaged coolingICP’s residential packaged single-phasegas-electric, cooling only and heatpump line includes 10 SEER modelswith a 10-year warranty and 12 SEERmodels with a 25-year warranty on thestainlesssteel heatchanger.Dischargeis convertiblefor horizontalordownflowapplications. Other features includeexternal gauge ports, integral base railsand an easy access control panel.Int’l Comfort Products Circle no. 317Mini-split systemsFujitsu has expanded its Halcyon IAQline of quiet single zone ductless minisplitair conditioners, adding 9,000 and12,000 Btu/h 13 SEER models to existing18,000 and 24,000 Btu/h models. Anextra-quiet ‘sleep mode’ fan settingallows virtual silent running. Theseunits operate on R410A refrigerant.Fujitsu General America Circle no. 318Digital thermostatThe Amana programmable digital thermostatwith humidity control adapts tomost 24 volt systems. It automaticallyadjustsblower speed,increasesair dischargetemperatureinheat pumps and electric heating modes,and makes the heating/coolingchangeover. It can operate single andmulti-stage systems and features sevenday programming.Goodman Canada Circle no. 319Portable coolingThe MovinCool Office Pro 36 produces36,000 Btu/h of spot cooling. Featuresinclude low temperatureoperation,standard safetyAFCI plug,programmablecontrols and optionalPlug N’ Playpump for automaticcondensatedraining. It isdesigned for work spaces up to 2,400-sq.ft. and operates on 230 volts. Othermodels <strong>are</strong> available for larger spaces.G.R. Williams Circle no. 320Multi-zone coolingCity Multi systems use R410A refrigerantfor a higher Coefficient of Performance(COP) of 4.13 vs. 3.52 with R407C and2.75 with R-22. This reduces modulespace requiredby 35percent with a26 hp system,for example.Piping is alsoreduced, from1-1/8" to 7/8"for gas andfrom 1/2" to 3/8" for refrigerant forgreater installation savings.Mitsubishi Electric Circle no. 321Wine cellar controlThe Wine Guardian by Air Innovationsis a line of thru-the-wall coolingsystems for wine cellars. These self-containedductable units feature highcapacityfans, commercialcomponen t s ,Quick TipKeep it in the shade!By Jerry BoulangerThe efficiency of air-cooled condensing equipment can beimproved by locating it so that it is shaded.ARI rating conditions for central system condensing unitstypically used in residential applications <strong>are</strong> at 95°F airtemperature entering the condenser. If the air entering thecondenser is reduced to 85°F, the total cooling capacityincreases by about seven percent and the compressor powerrequired drops by about four percent.Conversely, if the air temperature is 105°F (not unusual for roof-mountedunits), the total cooling capacity decreases by about seven percent and thecompressor power increases by about 13 percent. (These numbers <strong>are</strong>based on published performance for a Carrier model 38AK008 condensingunit at 45°F SST.)It’s well worth it, then, to think about the location of this type ofequipment and take advantage of any shade available. It may even makesense to provide shading if no natural option exists. The equipment will alsolast longer running in less severe conditions.Jerry Boulanger is marketing manager for Axiom Industries Ltd.,Saskatoon, Sask.
