“…Beshada et al [4] analyzed the performance of a solar energy greenhouse, oriented due south to absorb maximum solar energy, and had a north wall to store solar energy at daytime, which has been efficiently used in China to grow vegetables and flowers during the wintertime, under cold weather conditions. Saravia et al [8] discussed greenhouse solar heating in the Argentinean north-west in order to increase the average night temperature and avoid freezing problems inside greenhouses, for local meteorological conditions. Impron et al [6] developed a greenhouse climatic model to optimize cover properties and ventilation rates for the tropical lowlands of Indonesia.…”

This paper presents an approach to determining the optimum orientation of a greenhouse for year round applications for different climatic conditions. The most commonly used uneven-span single shape of greenhouse in east-west and north-south orientation have been selected for comparison. Total solar radiation input to each wall, included surfaces and roofs, is computed for both solar greenhouse orientation and compared for each month of the year at different latitudes at the northern hemisphere. Experimental validation is carried out for the measured global solar radiation data for horizontal surface and south wall at (44° N and 20° E), Belgrade, Serbia. The predicted and measured values are in close agreement. Results shows that east-west orientation of uneven-span solar greenhouse is the best suited during each months for all analyzed latitudes.

Drying is one of the most important unit operations for food preservation and storage. It is a energy intensive process and with the increase in the price and demand of electricity, renewable energy (solar) is proving its worth. Greenhouse dryers are low cost, easily constructible and can be utilised for invariably majority of agricultural commodities. The above attributes accounts for its high popularity in the Indian sub continents and Africa. An attempt has been made to generate a comprehensive review on the application, advances in construction, modelling, simulation and economics of the solar greenhouse dryers.

“…Also it might be performed using electrical energy [12]. Apart from the listed above heating systems, there exist alternative variants, for example, using heat pumps [13,14] , or sun collectors [15,16]. Nowadays the systems for radiant heating are widely used in agriculture due to the following reasons [17][18][19][20]: 1) It is an artificial source for infrared (Sun) radiation; 2) Where is no need for boiler plant and associated equipment;…”

Abstract. Commercially available greenhouses are commonly used for provision of year-round growing of agricultural crops at protected ground. In order to provide favorable conditions for plants growth these agricultural constructions should be equipped by artificial heating systems in cold seasons. This work presents an overview of basic traditional and alternative heating systems which find their applications in agriculture. Advantages of application of roof radiant heating with infrared radiation sources for greenhouses are discussed. It was discovered that now there is no appropriate mathematical model of greenhouse radiant heating, which takes into account both heat and mass exchange processes. Here we propose a mathematical model of radiant heating, which includes equation system of both heat and mass exchange processes for greenhouse, its enclosure and soil. The numerical calculations were performed for commercially available greenhouse "Farmer 7.5". We investigated the impact of external air temperature and heat exchange rate on the following greenhouse radiant heating characteristics: internal air temperature, heating system thermal power and water discharge for soil watering.
