Abstract
Based on the 24V DC rolling rotor compressor having the advantages of structural simplicity, light weight, small clearance volume, high exhausting coefficient, we design and build a solar photostatic DC refrigerator with an effective volume of 53 liters. We integrate solar photostatic panels with the refrigerated cabinet, and use solar power collection system and Agilent 34970A data acquisition instrument to collect voltage, current, electric quantity and temperature of integrated solar refrigeration system components. Experimental results show that: the integrated solar refrigerators operate reliably in Harbin. The two solar panels placed on the top of the box respectively stick attached to the sidewalls of the box and tilted at 48 degrees towards south, each with the maximum daily power generation 0.45kW.h. No-load and full-load running of the compressor running rate are 21.1%(24h) and 18.6%(24h), and the average power consumption respectively is 56.6W and 61.2W, the daily electrical power consumption is 0.29kW.h and 0.27kW.h. The generating capacity can meet the normal demand of the compressor for five consecutive rainy days. It means the various components can match reasonably. The study provides reference valuable to the integrated solar refrigerators commercialization.
