Abstract: In zero energy houses, heating load would be reduced sharply during winter, as its building envelope is highly insulated. The normal compressor is triggered by a low load operation leading to more frequent on–off cycling. This paper presents a novel control algorithm named fan intermittent operation, for the indoor unit of room air conditioner removing the compressor on–off cycling under low load condition and to provide stable warm air to satisfy the task of local domain with extremely low compressor frequency. Based on periodic variation control of condensing temperature, a 5% energy saving rate can be established under the winter condition simulation.
