小型户式直接蒸发式地源热泵机组的设计
|
摘要
为了解决北方农村的清洁供暖问题,自行设计了一种适于北方广大农村住宅制冷和制热的直接蒸发式地源热泵分体式空调机组,将各部分集成,并通过可变温度热源对机组进行了测试,测试结果显示在满足冬季室内温度18℃的条件下,低温热源的温度达6℃机组能效比EER能达到4.0及以上,在典型农户实际应用整个供暖季的费用约为1500元,能够在农村地区推广应用。
In order to solve the problem of clean heating in rural areas of northern China, we designed a direct evaporative ground source heat pump split air conditioning unit suitable for refrigeration and heating of rural houses. Each part is integrated, and the unit is tested by variable temperature heat source. The test results show that under the condition of 18℃ indoor temperature in winter, the energy efficiency ratio EER of the unit with low temperature heat source up to 6℃ can reach 4.0 or above. The cost of the whole heating season is about 1,500 yuan, which can be popularized and applied in rural areas.
