太阳能供暖效果与猪舍保温状况和供暖方式的关系
Relationship of Solar Heating Effect and Thermal Insulation Condition and Heating Mode in Nursery Pig House
摘要
Abstract
Beijing has gradually banned coal-fired heating,and pig farms are in urgent need of clean and economical heating methods.This paper had been theoretically calculated solar heating standard configuration parameters and housing consumption in the case of thermal insulation and non-thermal nursery pig house.In addition,the energy saving effect and static payback period of solar heating were compared between four ways:insulation or non-insulation nursery pig house adopts convection heating or ground heating.The results showed that:under the condition of experimental nursery pig house and Beijing peak and valley price,the standard configuration solar energy in insulation nursery pig house compared with the standard configuration solar energy in non-insulation nursery pig house,the former reduced the standard allocation of solar energy system investment by 58.3％,the total investment increased by 1.5 × 103 yuan per year,but the operating cost was reduced by 9.4 × 103 yuan per year (59.5％),the total static investment recovery period was reduced from 6.8 years to 2.8 years.In the configuration of 5 solar collectors,compared with the convection heating without insulation,the energy saving ratio of solar heating system using floor heating and increasing insulation wall was increased from 4.8％ to 18％;adding the insulation wall was more economical than increasing the standard area solar collector.Standard area solar collector system in insulation nursery pig house was more energy efficient and lower carbon emissions than standard area solar collector system in non-insulation nursery pig house.The best effect of solar assisted electric heating in nursery pig house was combined with carrying on insulation reconstruction and floor heating.关键词
