Abstract
The invention provides a cold-hot independent circulation calorimeter durability test device comprising a first meter clamping device and a second meter clamping device. The cold-hot independent circulation calorimeter durability test device also comprises a cold water tank, a cold water pump and a cold water flow regulating and control module which are connected in turn, and a hot water tank, a hot water pump and a hot water flow regulating and control module which are connected in turn. Two sets of flow regulating and control modules are set to regulate the flow of cold and hot water respectively, the flow regulating and control modules are not repeatedly impacted by cold and hot water, and the accuracy of all sensors and instruments is not liable to decrease or fail to work so that the measurement accuracy is relatively high and reliability and the service life are also relatively high. Besides, two meter clamping devices are arranged, and cold water impact is performed on the other meter clamping device when hot water impact is performed on one meter clamping device so that the influence on the accuracy of the test result due to instant impact force caused by the fact that a pipeline of cold water or hot water is closed and then opened again can be avoided.
