TERMOSTATISK REGLERANORDNING FOR EN KLIMATISERINGSANLEGGNING

摘要

The invention relates to a thermostatic regulator assembly which has the dual function of controlling both the heating and air conditioning equipment of a building. The assembly basically incorporates a first valve unit for controlling the flow of a heating fluid such as steam or hot water and a second valve unit for controlling the flow of air which in turn can control the regulator of a damper system of ducts which supply cooled air for air conditioning. The first valve unit is operative when it is open and the second valve unit is operative when it is closed. Thermostatic motor means operate the first and second valve units sequentially so that they are sequentially effective for first and second temperature ranges which correspond to heating and cooling condition requirements. The second valve unit may have a valve seat in the form of a nozzle and a closure member in the form of a baffle plate.
