TEMPERATURE CONTROL OF BUILDING HEATING SYSTEM Russian patent published in 2010 - IPC G05D23/02 F24D3/00 

FIELD: heating.

SUBSTANCE: in temperature control of building heating system, as temperature sensing element there used is liquid thermomechanical converter (LTC) with rigid housing, which consists of cylindrical hollow housing with a plug, and with a packing arranged in it, through which LTC stock moves, on inner end of which there is disc head which serves as a stop for LTC spring serving for easing backward movement of the stock at decrease of temperature of thermometric liquid with which the tight cavity of LTC is fully filled. At that, diametre of stock is considerably smaller than inner diametre of LTC housing, and between LTC plug and heat insulated bushing of partition there installed is spring pressing LTC bottom to adjustment screw installed in end wall of thermostatting chamber and serving for installation of thermostatting temperature of return water.

EFFECT: increasing efficiency and enlarging the control range of water temperature control in heating system at improving the reliability of control and simplifying its construction.
