For these spaces, the \u003cstrong\u003eTOSOT TK-H05TC\/NhA-D(U)\u003c\/strong\u003e model is the 5 ton size in the lineup, that is 60,000 BTU\/h nominal. It is a fully electric \u003cstrong\u003eRooftop R32 packaged heat pump:\u003c\/strong\u003e compressor, coils and fan are brought together in a single outdoor cabinet, connected to the building's duct system, for heating as well as for cooling.\u003c\/p\u003e\n\u003cp\u003eTOSOT, a brand of the Gree group, presents this unit as a “DC Inverter Rooftop Ultra Heat Fully Electric Heat Pump”. No gas is required: the unit runs on \u003cstrong\u003eR-32\u003c\/strong\u003e refrigerant and is powered in \u003cstrong\u003e208-230 V single-phase\u003c\/strong\u003e, which suits commercial buildings that do not have three-phase service.\u003c\/p\u003e\n\u003ch3\u003eAirflow, the first criterion in a large space\u003c\/h3\u003e\n\u003cp\u003eIn a large volume, capacity is of no use if the air does not reach the back of the room. The centrifugal indoor blower of the 5 ton moves \u003cstrong\u003e1,600 CFM\u003c\/strong\u003e at high speed, 1,200 CFM at medium speed and 1,100 CFM at low speed. External static pressure is 0.5 in. as standard and can reach 0.8 in. at most, which leaves a margin for longer duct systems, typical of large commercial spaces.\u003c\/p\u003e\n\u003cp\u003eThese three airflows make it possible to match the distribution to the layout of the duct system. Before the installation, we examine the placement of the diffusers and of the return grilles: in an open-plan room, a poorly placed return can leave warmer or cooler zones, even with a properly sized unit. The air passes through an aluminum air filter before being distributed.\u003c\/p\u003e\n\u003ch3\u003eCapacities matched to the volume\u003c\/h3\u003e\n\u003cp\u003eThe 5 ton is certified under AHRI reference 218471412 and ENERGY STAR certificate 4624790. Its nominal capacity is 60,000 BTU\/h; the certified values are 56,000 BTU\/h in cooling at 35 °C and \u003cstrong\u003e57,000 BTU\/h in heating at 8.3 °C\u003c\/strong\u003e. Thanks to high-efficiency DC Inverter technology, capacity varies with demand, within the ranges published by TOSOT:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ecooling: from 14,000 to 58,800 BTU\/h;\u003c\/li\u003e\n\u003cli\u003eheating at 8.3 °C: from 14,250 to \u003cstrong\u003e62,700 BTU\/h\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat range matters in a space whose occupancy changes over the course of the day. A store that is nearly empty at opening and busy in the afternoon does not have the same needs from one hour to the next: the compressor modulates its speed instead of running in full cycles. Seasonal efficiency is read in the certificates: \u003cstrong\u003eSEER2 of 18.0\u003c\/strong\u003e, EER2 of 11.2 and HSPF2 of 8.3 (region IV).\u003c\/p\u003e\n\u003ch3\u003eKeeping a large space heated in cold weather\u003c\/h3\u003e\n\u003cp\u003eA large volume loses a lot of heat in deep cold, especially near the entrance doors and the display windows. The 5 ton is \u003cstrong\u003eENERGY STAR Cold Climate certified\u003c\/strong\u003e and operates in heating at outdoor temperatures from -30 °C to 24 °C. The certified data provides two benchmarks:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e34,000 BTU\/h at -8.3 °C (17 °F), the certified rated capacity;\u003c\/li\u003e\n\u003cli\u003e51,000 BTU\/h at -15 °C (5 °F), measured at maximum compressor speed, with a \u003cstrong\u003eCOP of 2.00\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe figure at -15 °C is higher than the one at -8.3 °C because it does not measure the same operation: the first corresponds to the compressor pushed to its maximum speed, per the ENERGY STAR Cold Climate criterion, the second to the certified rated capacity. A COP of 2.00 means that at -15 °C, the unit delivers 2.00 units of heat for every unit of electricity consumed. The Inverter rotary compressor with vapour injection (EVI) and the electronic expansion valve are part of the equipment TOSOT describes for this “Ultra Heat” model, with \u003cstrong\u003eheating down to -30 °C\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eFor buildings that want an additional reserve, TOSOT offers optional electric backup heat kits of 5, 10, 15 or 20 kW on the 5 ton. The choice is made after the heat loss calculation and the review of the electrical panel, since each kit adds its own load to the circuit.\u003c\/p\u003e\n\u003ch2\u003eRoof installation: curb, clearances and the AirGreen team\u003c\/h2\u003e\n\u003cp\u003eA unit of this size calls for careful preparation of the roof. At AirGreen, the installation is carried out by our own team, which takes charge of planning the curb, respecting the clearances, the handling and the start-up.\u003c\/p\u003e\n\u003ch3\u003eThe roof curb and the connection to the ducts\u003c\/h3\u003e\n\u003cp\u003eTOSOT publishes the roof curb dimensions for the 5 ton. With a vertical connection, the supply and the return air pass through the bottom of the cabinet, through that curb; with a horizontal connection, the ducts connect on the side. In an existing building, we compare the published dimensions with the opening and the curb in place, if there is one, in order to determine the roofing work required before the unit is delivered.\u003c\/p\u003e\n\u003ch3\u003eClearances to respect around the cabinet\u003c\/h3\u003e\n\u003cp\u003eThe technical sheet publishes the installation clearances to allow for around the unit. We respect them on every installation: they ensure access for maintenance and the free circulation of air around the cabinet. On a commercial roof that already holds other equipment, this point often guides the choice of location. We also take into account the published sound pressure of 68 dB(A), keeping the unit away from windows and neighbours when the roof allows, as well as snow accumulation on the roof.\u003c\/p\u003e\n\u003ch3\u003eWeight, dimensions and handling\u003c\/h3\u003e\n\u003cp\u003eThe cabinet measures 44 × 44 × 49-1\/4 in. (1,120 × 1,120 × 1,250 mm), in width, depth and height. It weighs 629 lb net and 650 lb gross, and holds 205 oz of R-32 refrigerant. Before installation, we check that the roof structure can take that load at the planned location and we plan the handling up to the roof according to the access to the building.\u003c\/p\u003e\n\u003ch3\u003ePower supply and control\u003c\/h3\u003e\n\u003cp\u003eThe technical sheet lists an MCA of 39.1 A and an MOCP of 45.0 A, in 208-230 V single-phase (1 phase, 60 Hz). We pass these values on to your electrician for the preparation of the circuit, adding the load of the backup kit if you choose one. For control, the unit accepts a standard 24 V thermostat from another manufacturer or the TOSOT RS485 thermostat; the standard controller listed in the sheet is the XE7C-23\/H. In a store, we place the thermostat where it reads a temperature representative of the room, away from the doors and the display windows.\u003c\/p\u003e\n\u003ch3\u003eHow a project unfolds with our team\u003c\/h3\u003e\n\u003cp\u003eFor a commercial project of this size, here is how we proceed:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ea visit to the space, measurements and inspection of the duct system and of the diffusers;\u003c\/li\u003e\n\u003cli\u003ecalculation of the heating and cooling needs according to the volume, the occupancy and the building envelope;\u003c\/li\u003e\n\u003cli\u003ea roof plan: location, roof curb, clearances and vertical or horizontal connection;\u003c\/li\u003e\n\u003cli\u003ecoordination with your electrician for the circuit and any backup kit;\u003c\/li\u003e\n\u003cli\u003einstallation by our technicians, connection to the ducts and start-up;\u003c\/li\u003e\n\u003cli\u003ean explanation of the settings and of the thermostat to the manager of the space.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf your project calls instead for a smaller capacity, or if you want to compare the brands of the Gree group, our \u003ca href=\"\/en\/collections\/thermopompe-monobloc-installation-partout-a-montreal-laval-longueuil-rive-sud-et-rive-nord\"\u003epackaged heat pumps\u003c\/a\u003e page presents the Rooftop R32 models we install, from 2 to 5 tons.\u003c\/p\u003e\n\u003ch3\u003eLet's talk about your large space\u003c\/h3\u003e\n\u003cp\u003eWe install the \u003cstrong\u003e5 ton TOSOT packaged heat pump\u003c\/strong\u003e in the stores, workshops and halls of Montreal, Laval, Longueuil, the North Shore and the South Shore. 100% free on-site estimate everywhere in Montreal, Laval, Longueuil, North Shore and South Shore: call AirGreen at 514 316-2973 to have your space, your roof and your ducts assessed by our team.
