The YORK Sunline XN048 \u003cstrong\u003epackaged heat pump\u003c\/strong\u003e (4 tons, 48,000 BTU\/h nominal) is built for 575 V, delivered with a factory economizer and charged with R-410A. AirGreen, a Montreal HVAC contractor, installs it on industrial roofs in Montreal, Laval, Longueuil, the North Shore and the South Shore.\u003c\/p\u003e\n\u003ch3\u003eThe mechanical side stays outside, the occupied rooms stay clear\u003c\/h3\u003e\n\u003cp\u003eA packaged heat pump houses its scroll compressor, its coils, its fans, its filters and its control in a single outdoor cabinet, set on the roof or on a pad at grade; only the ducts enter the rooms it serves. For a control room or a cafeteria, maintenance happens up there, without disturbing the operators or the employees on break. Every unit leaves the factory charged, wired and tested.\u003c\/p\u003e\n\u003ch3\u003eNo transformer between the 575 V panel and the unit\u003c\/h3\u003e\n\u003cp\u003eThe XN048C00B5C1AAA1A2 unit leaves the factory ready for a 575 V, three-phase, 60 Hz supply: no step-down transformer is required. According to the YORK guide, the applied voltage can range from 540 to 630 V.

At 575 V, the indoor fan is always belt-driven, direct drive being reserved for the 208\/230 V models; its adjustable-pitch pulley allows the airflow to be matched to the duct system.\u003c\/p\u003e\n\u003ch3\u003eStaying with R-410A, with no break for the maintenance team\u003c\/h3\u003e\n\u003cp\u003eThe unit uses \u003cstrong\u003eR-410A\u003c\/strong\u003e, a previous-generation refrigerant whose technology is proven. If your other units run on it as well, your technicians keep a single refrigerant and their usual procedures. Placed on the suction line, a freeze-protection thermostat guards the unit against a loss of refrigerant and keeps the coil from icing up when the economizer sends in cool air while the compressor is running.\u003c\/p\u003e\n\u003ch3\u003eA single footprint for the ZE and XN series from 3 to 6 tons\u003c\/h3\u003e\n\u003cp\u003eYORK uses one cabinet for every ZE and XN size and configuration from 3 to 6 tons: the same \u003cstrong\u003eroof curb\u003c\/strong\u003e, 8 or 14 in. high, takes them all. We can therefore set the curb during the roofing work and settle the size of the unit and its heat option later, once the internal loads are worked out: the control room screens, the cafeteria occupancy, the kitchen appliances. An XN of 3, 4 or 5 tons will take the same space.\u003c\/p\u003e\n\u003ch3\u003eThe factory economizer, an asset for staff rooms\u003c\/h3\u003e\n\u003cp\u003eInstalled and wired at the factory, the \u003cstrong\u003eeconomizer\u003c\/strong\u003e brings in up to 100% fresh air as soon as the outdoor dry-bulb temperature drops below its set point. A control room full of screens or a cafeteria packed at noon then gets free cooling in spring and in fall; the control can lock out the compressor.\u003c\/p\u003e\n\u003cp\u003eWith no factory barometric relief damper, the air brought in has to find a way out: YORK offers that damper as an accessory, or a 575-3-60 powered exhaust for bottom-connected ducts. For the cafeteria, a CO2 sensor offered as an accessory takes over the economizer when the concentration rises above the preset limits.\u003c\/p\u003e\n\u003ch3\u003eControl room: operator comfort or equipment cooling\u003c\/h3\u003e\n\u003cp\u003eThe Smart Equipment control includes a low-ambient function: with no accessory, the unit can cool at an outdoor temperature as low as 0 °F (-17.8 °C) when it serves human comfort. Cooling electrical gear or servers in the middle of winter is closer to process cooling. YORK then recommends calling on its applications department, because stable operation below 30 °F (-1.1 °C) may require additional accessories.

Its nickel-chrome elements are protected by auto-reset limit switches; for maintenance, the whole heating section slides out of the unit. With a kit, the airflow has to reach at least 1,200 CFM.
