Problems solved by technology
Due to the high labor intensity and long working hours of manual testing, it is difficult to continuously measure each parameter point for a long time, the test is difficult, and the parameter collection density is low, so many manufacturers cannot conduct qualified tests on their cooling towers. It is also difficult for the unit to make an objective evaluation of the performance of the cooling tower in operation
Cooling tower performance is difficult to guarantee

A wireless testing equipment and the testing method of the refrigerating tower capability. The testing equipment is that the data receiver connects with the portable computer, the wireless wet and dry bulb temperature collective module, the wireless intake temperature collective module, the wireless delivery temperature collective module, the wireless water-flow collective module, the wireless wind speed collective module and the wireless power quantity collective module respectively. The testing method is that the portable computer continuously and high-density read the applied local operating circumstances of the refrigerating tower by the wireless mode, calculate automatically the ingoing air enthalpy and the outgoing air enthalpy of the refrigerating tower, and also calculate the cooling value of the refrigerating tower and the power consumption ratio of the blower fan. The advantages of the invention are: the capability testing equipment of the wireless modularize refrigerating tower, the structure of it is in focus, the fixing and using is convenient, is fit for the applied local test of the refrigerating tower; the portable computer continuously and high-density read the operating circumstances of the refrigerating tower, automatic calculate the cooling value of the refrigerating tower and the power consumption ratio of the blower fan, that provide the effective testing method for the capability test of the refrigerating tower.
Description
technical field [0001] The invention relates to a wireless cooling tower performance testing device and testing method. Background technique [0002] At present, the performance testing method of cooling towers at home and abroad is manual. During the test, multiple people are distributed at different test points to collect the operating parameters of the cooling tower synchronously; the performance of the cooling tower is calculated through the operating parameters of the test. Due to the high labor intensity and long working hours of manual testing, it is difficult to continuously measure each parameter point for a long time, the test is difficult, and the parameter collection density is low, so many manufacturers cannot conduct qualified tests on their cooling towers. It is also difficult for the unit to make an objective evaluation of the performance of the cooling tower in operation. Cooling tower performance is difficult to guarantee.
