The invention relates to heating from hot water installations in a closed heating system.Known heating system and hot water containing the boiler, the surface of the water heater, the inlet of the latest cooling line is connected to the output of the boiler through the supply pipeline, and the output to the input of the boiler by means of reverse pipeline, equipped with a pump, the output surface of the water heater by line heating is connected to the hot water pipeline and connected to the supply main pipeline supply pipe heating system and connect the jumper with control valves the first of which is connected to the reverse main pipe downstream of the pump and the delivery pipe of the heating system, the second is to reverse the main pipeline between the inlet of the boiler and the connection point of the first bridge and to the supply main pipe between the boiler outlet and the place of connection of the feed pipe heating systems, third - pipe hot-water supply and return pipe of the heating medium and the system further comprises two bulb, the first of which is installed indoors, and the second on the hot water pipeline, on the back of the trunk pipeline at the outlet of the water heater control valve is installed, the first bulb is connected with the regulating valve of the first jumper and the second valve of the second jumper and reverse main line, and the system comprises a tank battery and backup control vessel and tank battery connected to the opposite main pipeline and communicated through pipe transfusion-filling with a backup control vessel (Ed. St. 1643879, MKI CL. F 24 D 3/08).Known heating system of the premises has high complexity and low effektivnim pump, installed with connections to the pipeline with warm water, and pipeline with cold water, and in the circuit of the heat pump is equipped with two air heat exchanger with fans for cooling the air in summer and heat from outside air in mid-season period.System space heating is illustrated a block diagram of a split-system air conditioning - heat pump of Fig. 1. It contains the main pipelines are heated and cold water 1 water 2 Central heating, and heat pump consists of a compressor 3, a water heat exchanger 4, the two-way valve 5, the air heat exchangers 6 and 7 with the fans 8, 9 and choke 10. The system is equipped with valves 11, 12, 13, 14 and 15, 16.The heating system of the premises is as follows. Water heated in the Central heating system, supplied by pipeline 1 in the water heat exchanger 4 of the heat pump, where the heat from the water during boiling of the refrigerant circulating in a closed circuit through the compressor 3, the two-way valve 5, a throttle 10 and the air heat exchanger 6 with fan 8. Selected from water the heat released during condensation of refrigerant in Teploobmennik 4 is connected to the main cold water pipe 2 through valves 11, 12, 13, 14, the valve 5 is switched to the position of the backflow of the refrigerant circuit of the heat pump. While in the air heat exchanger 6 is the refrigerant and the cooling fan 8 room air and in the water heat exchanger 3 is heated cold water due to the condensation of the refrigerant.In the mid-season period, the water heat exchanger 4 is shut down by valves 15, 16, the valve 5 is switched to the heating mode space (similar to the winter period) and the heat from the air outside the room is with air heat exchanger 7 with fan 9. Using a temperature sensor (not shown) located in the premises and that is configured to set temperature, automatically switching on and off of the compressor 3, which ensures the stable functioning of the system.The use of a heat pump in the heating system will significantly improve the efficiency of thermal energy.From the energy balance implies that the amount of heat Q1 produced at the heating station, the sum of the heat losses in the mains Q2 and the amount of heat Q3, directly spent on heating R>k - coefficient of thermal conductivity;
T1 = T1-T0 and T2 = T2-T0 is the temperature difference between heat (direct and inverse) and the environment.For Q3 have the appropriate expression
Q3 = CmT12,
C - the specific heat of water;
m - water consumption per unit of time;
T12 - temperature difference, made by the consumer.From these estimates it is seen that the heat loss in the mains can be reduced significantly by reducing the absolute values of T1 and T2 and, consequently, reduce T1 and T2. In the end, you can implement two variants of the heating system: either to reduce fuel consumption at the heating station while maintaining the amount of heat for heating of buildings (m,T12 = const), or to increase the amount of heat for heating of buildings due to savings in transportation on highways (increase T12) while maintaining the total thermal power station. It is these opportunities and allow for heat pumps (HS).Managed directly by each consumer consumption of thermal energy will naturally lead to its economy. For this reason, despite the slightly lower efficiency of individual TN low power (3 - 10 kW of heat) compared to TN the programme of consumption and quick on and off heating.According to the invention, fabricated and tested an experimental sample. 1.
