The aim of the contribution of this paper is the use of a blower (pumping ambient air through a series of pipes through the earth's crust at the required depth) and electrical appliances which are powered by solar photovoltaic modules. The net air temperature obtained by pumping with a blower is supplied to a 300 m3 hospital ward with 13 patients, 13 nurses, 1 nurse and 1 doctor. The analysis is carried out for January and May. In January, the ambient air is pumped by a blower to a depth of 3.04 m through pipes having a temperature of 24oC[23]. The ambient air reaches 24oC in January and is sent to a hospital ward maintained at 24oC. In May, after passing the ambient air for a certain length at a depth of 3.04m, it reaches 24oC and the same air again is passed through well water situated at a depth of 10m[11] from the earth's surface with a temperature of 18oC[12] and with the result after passing a certain length and is pumped to hospital ward maintained at 18 oC. For the operation of the blower and electrical appliances, it is sufficient to have 7328 modules in parallel and 2 modules in series of SW280 solar photovoltaic modules, and the remaining extra current after meeting the requirement of the blower and electrical appliances is stored in the rechargeable battery. The amount of electric charge stored and discharged by the rechargeable battery in January and May is 63672.459Ah, 16881.932Ah and 70080.245Ah, respectively 39523.542Ah with a battery capacity of 191708.798Ah.
