Pneumatic energy saving control

摘要

The objective of the invention is to bypass the existing pneumatic thermostats/controllers providing on off auto operation for VAV boxes, reheat coils, classroom unit ventilators, fan coil units, fin tube radiators, damper actuator's, water control valves and the like, with a remotely controlled three way valves and wireless controlled and self-contained power.

主权项

1. A pneumatic thermostat by-pass control device comprising:
(i) a wireless communication module for receiving wireless on/off/auto output signals from a control computer; and (ii) a pneumatic valve switching module in communication with said communication module, wherein said valve switching module comprises a first pneumatic input, a first pneumatic output and a first switching valve, wherein said first pneumatic input and said first pneumatic output are pneumatically connected to said first switching valve, wherein said first pneumatic input is configured to be pneumatically connected to a pneumatic thermostat and wherein said first pneumatic output is configured to be pneumatically connected to a pneumatically controlled environmental control device; a second pneumatic input, a second pneumatic output and a second switching valve, wherein said second pneumatic input and said second pneumatic output are configured to be pneumatically connected to a main air supply and said second pneumatic output is configured to be pneumatic communication with the pneumatically controlled environmental control device; wherein, in response to said wireless on/off/auto output signal from said control computer, said communication module sends an input signal to said pneumatic valve switching module; and wherein in response to said input signal, said pneumatic valve switching module changes the position of said first or second switching valves to send a pneumatic output signal to said pneumatically controlled environmental control device.
