Abstract

The invention relates to the technical field of air volume detection of air outlet devices. The invention provides an enthalpy difference chamber circulating air volume measuring device and an initialopening method of a nozzle thereof. The enthalpy difference chamber circulating air volume measuring device comprises a receiving chamber, an exhaust chamber, a pressure sensor, a control device andan alarm device; the receiving chamber communicates with the exhaust chamber through at least two nozzles; the pressure sensor is arranged in the receiving chamber; the control device is in communication connection with the pressure sensor; the control device is in communication connection with a switch of the nozzles, and the control device is in communication connection with the alarm device. According to the initial opening method of the nozzles of the enthalpy difference chamber circulating air volume measuring device, an air volume value interval and a nozzle corresponding table are set for a control device; according to the nominal air volume value of to-be-measured air, the nozzle needing to be opened is selected in the air volume value interval and the air volume value interval where the nozzle corresponding table is located, and finally the control device controls the selected nozzle to be opened, so that automation of initial opening of nozzles is achieved.

Description

technical field [0001] The invention relates to the technical field of air volume detection of an air outlet device, in particular to a device for measuring circulating air volume in an enthalpy difference chamber and an initial opening method for a nozzle thereof. Background technique [0002] The circulating air volume measurement device of the enthalpy difference chamber usually includes a receiving room, an exhaust room, nozzles and an exhaust fan. On the wall between the chamber and the exhaust chamber, air is exhausted from the receiving chamber to the exhaust chamber through nozzles. [0003] According to the regulations of GB / T7725-2004, the wind speed at the throat of the nozzle should be between 15m / s and 35m / s, and the static pressure value of the receiving chamber should be adjusted to 0. In order to meet these requirements, it is necessary to control the different opening situations of the nozzles as well as to control the exhaust fans. [0004] However, in th...
