The engineering company COINGES and the manufacturer of air conditioning systems LENNOX contrast at the air-conditioning exhibition of IFEMA (in Madrid) the advantages of the use of probes in environment instead of their installation inside their ROOF-TOP. This saving measure is being monitored by COINGES, at the University Hospital Río Hortega in Valladolid, within the European project LIFE SMART HOSPITAL.
LENNOX designs its equipment to be ‘plug & play’ and the placement of the probe in the local environment has the disadvantage that it should be installed separately. It also has the disadvantage that it must be placed in a site representative of the place; when the probe is placed in the machine, the incoming air is the air in the room and, in principle, is the temperature in the room, however, when the probe is place on the walls, it may not give sufficiently representative values, especially in large spaces, where LENNOX ROOF-TOPs are installed.
The high efficiency of the fans that LENNOX assembles in its equipment also reduces the savings that would be obtained it these fans were conventional. However, the percentage of electric savings in air transport would be maintained according to the results of the LIFE SMART HOSPITAL PROJECT, and direct savings will be a function of the number of working hours of the machine. LENNOX will consider including the external installation of the probe as a savings proposal to its customers.
