Abstract: The present invention provides a heating, ventilation, and air-conditioning (HVAC) system using an A2L refrigerant and a method of installing the HVAC system in a building. The HVAC system includes an indoor unit having a heat exchanger that uses an A2L refrigerant, a blower, an outdoor unit, an A2L control board, and one or more A2L sensors configured to detect an amount of A2L refrigerant. In one or more embodiments, the indoor unit is electrically coupled to the blower, the A2L control board, and the outdoor unit. Also, in one or more embodiments, the A2L control board is also electrically coupled to the blower and the one or more A2L sensors.

Abstract: A method for transferring objects (2), wherein the objects (2) are fed in bulk in a loading region onto at least one first intermittently rotating disc (5; 6) of vertical axis, provided with a rim (9; 9') of holes (10; 10') for containing the objects (2); within a station (20; 20') there are provided members (21) which transfer the objects (2) from the holes (10; 10') of the first disc (5; 6) to the holes (18) of a second disc (15), and which engage each hole (10; 10') of the first disc (5; 6) once during every two revolutions of this latter.

Abstract: Disclosed herein is a method for wrapping batches of products, in particular candies, and for forming sealed packets, which envisages: a batch of products being supplied to a wrapping wheel; a sheet of heat-sealing material with two lateral downward turned borders being placed above the batch; the said borders being welded one to the other in order to form a tube, the opposite extremities of which are first flattened through the insertion in between them of divarication means; the said extremities then being sealed by welding/pre-folding grippers designed to make, on each welded tubular extremity, weakening lines that aid the subsequent folding of the said extremities.
