Abstract

A method of maintaining the soil discharge based on prediction of soil temperature changes when measuring the temperature of the brine at the outlet of the heat pump evaporator is proposed. Using the resulting integrated system for assessing change in soil temperature as part of a dynamic system: soil heat exchanger – heat pump evaporator allows to make decisions about change the brine flow rate based on the change of motor speed of circulation pump and to establish the exact soil discharge period. Maintaining soil discharge based on prediction of soil temperature changes allows, for example, reduce the cost of heat production and heat pump system payback within 15-25 % for manufacture of year 47 GJ• year of heat by saving electrical energy at a frequency regulation of the motor of the circulation pump, which in monetary is equivalent to 30 % of the overall savings provided by the replacement of natural gas.
