SYSTEM AND A METHOD FOR SUPPLYING NATURAL GAS USING A MIXING VALVE CAPABLE OF SUPPLYING THE NATURAL GAS TO DEMANDED PLACES AT A CONSTANT TEMPERATURE

摘要

PURPOSE: A system and a method for supplying natural gas using a mixing valve are provided to enable the installation of the mixing valve having small capacity because the mixing valve reduces temperature control range.;CONSTITUTION: A system(100) for supplying natural gas using a mixing valve(120) comprises a gas heater(110), a monostat(140), and a controller(130). The gas heater increases the temperature of gas. The monostat controls the pressure of the gas supplied from the gas heater. The mixing valve is installed in parallel to the gas heater and supplies the gas to be heated to the monostat. The controller measures the outlet temperature of the monostat and controls the opening degree of the mixing valve and the loads of the gas heater based on difference to the outlet temperature and a set temperature.;COPYRIGHT KIPO 2013
