摘　　要：本文以一种全热回收型空调机柜为研究对象,通过开关全热回收装置模拟了全热回收型空调机柜和普通空调机柜。利用DT-321s温湿度仪和AR866A风速仪测试了空调机柜的新风点、全热回收点、混合点、送风点的状态参数,基于空气焓差法计算了空调机柜的制冷量和能效比,并通过水流量计算方法进行了验证。研究结果表明:全热回收型空调机柜相较于普通空调机柜平均能效比高约12.31%,仅采用温湿度仪和风速仪测量空调机柜的制冷量与水流量计算制冷量结果相对误差在10%以内。This paper took a full heat-recovering air-conditioning cabinet as the research object,and simulated the full heat-recovering air-conditioning cabinet and ordinary air conditioning cabinet by turning on and shutting off the total heat recovery device.DT-321s temperature and humidity meter and AR866A anemometer were used to test the state parameters of the air-conditioning cabinet,including fresh air point,total heat-recovering point,mixing point,and air supply point.The cooling capacity and COP of the air-conditioning cabinet were calculated based on the air enthalpy method,which was verified by the water flow calculation method.The research results showed that the average COP of the fully heat-recovering air-conditioning cabinet was 12.31%higher than that of the ordinary air-conditioning cabinet.The relative error between cooling capacity of air-conditioning cabinet measured by temperature and humidity meter and anemometer and that calculated by water flow was no more than 10%.
