Abstract

Abstract. Introduction. Nowadays, solar air collector drying chamber is widely used for drying agricultural products. The solar air collector is one of the main devices of solar dryers and serves to heat the air supplied to the dryer to the required temperature. This scientific work presents the results of an experimental study of air temperature changes in a solar air collector intended for a solar dryer. The results of studies conducted on a typical day in May-October of the year and their analysis are also presentedUsul va materiallar. Quyosh havo kollektorining harorat rejimi va issiqlik samaradorligini hisoblash quyidagi usul yordamida amalga oshirildi. quyosh havo kollektori yuzasiga tushgan umumiy radiatsiya, quyosh havo kollektoridagi havo tomonidan olingan foydali issiqlik va quyosh havo kollektoridan umumiy issiqlik yo'qotilishi bilan.
Natijalar. Quyosh havo kollektorli va issiqlik nasosli qurilmalari asosida ishlaydigan kombinatsiyalashgan sovutish quritish kamerasi qurildi va ishga tushirildi, tajribani о‘tkazish metodtikasi ishlab chiqildi
Xulosa. Kombinatsiyalashgan sovutish quritish kamerasi uchun absorberida tо‘siqlari mavjud bо‘lgan quyosh havo kollektorining tajriba qurilmasi tayyorlandi va tajriba sinovlari о‘tkazildi. quyosh havo kollektorida havo haroratini о‘zgarishini aniqlash bо‘yicha 2023 yilning may-sentabr oylarining xarakterli kunlarida о‘tkazilgan tajriba tadqiqotlarida tashqi havo harorati 19...40℃ bо‘lganda, quyosh havo kollektori yordamida о‘rtacha harorati 50...77℃ bо‘lgan issiq havo olish, shuningdek, quyosh radiatsiyasi intensivligi 5,8...7,86 kVt/m2 bо‘lganda, foydali maydoni 2,52 m2 bо‘lgan quyosh havo kollektori yordamida 14,1...17,9 kVt·soat miqdorida foydali energiya olish mumkinligi aniqlandi.
