Closest to the claimed invention is a heating system EN 2303388, CL F24D 15/04, A24D 3/18, adopted by the author for the prototype. The system is used in the heat supply for space heating. The system includes a heating boiler with a circulating pump, supply and return piping, heaters, valves and fittings, as well as absorption refrigeration machine having a generator (boiler), evaporator and cooling system with absorption chiller evaporator connected in the supply pipe.

The disadvantage of the prototype is that the low-temperature chamber, which experts in refrigeration is called the evaporator, may not serve as the primary source of energy for absorption chillers, and other sources is the power, necessary to ensure the health of absorption refrigeration machines are missing.

The aim of the invention is to provide the most economical and convenient in the operation of the heating system and cooling systems, allowing you to get not only warm but also cold, combining the advantages of different heating systems and deprived of their main drawbacks.

The technical result consists in the reduction of energy consumption by use in a feed line of the heating system of the absorption machine for cooling with subsequent transfer of heat remaining at the outlet of the absorption refrigeration machines and heat from the refrigeration system of the absorption machine for heating and optimal temperature control in a heated room, as well as by removal of excessive heat at an elevated temperature from the premises.

The output of the generator of absorption refrigeration machines are connected thermostat, after which is connected one or more additional heating circuits containing the supply and return piping, heating appliances. Thermostat depending on the temperature in the heated room can automatically switch the direction of flow, or through heating devices and/or the return pipe. Cooling system the absorption refrigerating machine also contains a thermostat, which depending on the temperature in the heated room can switch the direction of movement of the heat carrier in the heating apparatus or cooling unit.

The peculiarity is that for use in the present invention can be used in almost any absorption refrigerating machine of appropriate power, able to work from the heated water or steam and having at least a generator (boiler) with the absorber, condenser, evaporator and a liquid cooling system condenser and/or the condenser and absorber. In refrigeration absorption machine may use additional parts and components in various combinations with design differences and peculiarities of the internal connections of the nodes absorption refrigerating mA the ins, inherent to a particular model of the refrigeration machine.

As a cooling device can be used radiator air-cooling fan 14 or the heat exchanger.

System heating and cooling works as follows.

From heating installation equipped with a temperature regulation system, the floor is less fluid in the form of heated water or steam temperature, necessary for normal operation of absorption chillers, which for ammonia refrigerating machine is 70-150 degrees.

Before serving, heat in the radiators heated water or steam passing through the generator (boiler) absorption-refrigerating machine 6, giving some of the heat for evaporation of refrigerant and absorbent. In the condenser, the absorbent condenses, giving up heat to the cooling system. After throttling the refrigerant boils in the evaporator at low pressure, taking heat from being in the refrigerator products. Later in the absorber, the refrigerant is condensed and routed back into the generator. In small refrigerating machines, generally used biznesowy way circulation with the use of hydrogen.

After absorption refrigerating machine 6 through the supply pipe 4, the coolant enters thermostat 7 main heating circuit, which depending on the temperature in the heated room will switch the direction of flow, or through heating devices 8 and/or through the jumper for bypassing in the return pipe 5.

Cooling system absorption-refrigerating machine 6 through the heat exchanger 9 transmits heat in the radiators 12 auxiliary heating circuit of the room.

At a sufficiently high temperature in pogrevom room thermostat 11 will automatically switch the direction of flow, with heaters in the cooling device 13, and then absorption-refrigerating machine 6 operates only as a cheap refrigerator.
