Definitions
- the object of the invention is a system for recovery of heat from solidifying large-size metal castings and for using it to heat casting moulds.
- Sand casting moulds made on the basis of certain resins, for example furan are characterised by a high moisture of surfaces, which results from the presence of a large amount of hydrogen isolated as a result of chemical processes of binding a resin and a hardener, taking place in the mass.

- the exchanger assembly has, at the input of the refrigerant, a first pressure sensor and a second control valve, and at the output - a third control valve and a second pressure sensor, and a bypass conduit of the refrigerant and an installed first control valve.
- At its output there is a condenser connected to a main tank for condensates.
- the refrigerating circuit is connected, at the output of the second pressure sensor, to a straight-through tank which is connected to an intermediate tank for refrigerant condensates and to the bypass conduit.

It has a gas space connected to the external atmosphere by means of a conduit on which a flow measuring element is located. Water part is determined by the maximum and minimum water levels for implementation of which two sensors are used.

At its input, there is a second ammonia concentration sensor, and at the output of the first pump assembly, there is a fourth check valve.
- the receiving installation for water after heating includes a second exchanger assembly.
- the input of this assembly of the receiving installation for water after heating is connected, by means of a fourth control valve and a second check valve located at its output, to the conduit of water before heating.
- a mixing device and a second temperature sensor At the output of the traditional heating medium, an eighth control valve is located.
- an eighth control valve At the input of the mixing device, between the conduit of water before heating, there is a ninth control valve and a fifth check valve.
- the entire system has a control device - processor. It is connected to two fault indicators: one based on sound and the other on light, as well as to the control valves, to the sensors and to the first and second pump assemblies.

- a water pump, mounted in the system is connected to a tank of working medium, and via its second pipe branching, it is connected to the heat exchanger which, through a peak load boiler, is also connected to a pipe conduit of hot air.
- a jet pump In the conduit of hot air, a jet pump is included which is supplied from the water conduit the other end of which is connected to a pouring tank of the casting mould.
