The invention relates to a power system, in particular for heating, hot water supply to individual houses, individual buildings using low-grade natural heat sources, domestic sewage and other waste heat.

Known device, in which the low-potential source used is the dependence on time of day and presence of large number of Sunny days. This circumstance does not allow to use them in mid-and high latitudes.

Also known installation, in which the low-potential source is used, the heat of the surface layers of the groundwater and the soil (RF application N 94033853, CL F 25 13/00, 1994).

The disadvantage of this setup is the low temperature potential groundwater and the soil, a large amount of drilling and excavation to accommodate bulky utilization heat exchangers.

Known also install heating and hot water, comprising a heat source of low potential - navathanee, the heat pump evaporator and the condenser, heating system and hot water. C. the USSR N 581357, CL F 24 D 17/00, 1977).

The disadvantage of this setup is the lack of efficiency due to the small value of the coefficient of heat transfer from the concrete base manure storage facilities, as well as the presence of large amounts of manure with the frequency of its replacement.

The present invention is to increase the efficiency of utilization of low grade heat.

To solve the problem installing heating and hot vodosnabzhenie and hot water contains as a heat source of low potential dewatering rods with mine waters and is further provided with at least two filters, which are placed in front of the evaporator of the heat pump.

Placing at least two filters in front of the evaporator of the heat pump allows you to clean mine water coming into the bilge the frames, from contamination, thereby preventing the formation of deposits on the walls of the evaporator, which increases the efficiency of utilization of low grade heat from contaminated streams and, as a consequence, increases the amount of recoverable heat. When one filter is in operation, the second filter reverse flow of clean water is regenerated, the capacity of the working filter is designed to filter the entire amount of mine water coming into the bilge the frames.

The drawing shows the installation of heating and hot water.

Installation of heating and hot water supply contains a heat source of low potential dewatering rods 1 with mine waters, at least two filter 2, one of which is working, and the second backup, the evaporator 3, a condenser 4, a compressor 5, regulirovanie evaporator 3 of the heat pump. The condenser 4 of the heat pump is connected to the heating system 7 and the high-speed heater 8 hot water systems. The pump 9 circulates water in heating systems and hot water. Filling water heating systems and hot water is produced from the technical water supply through expansion tanks 10. Dies 11 and 12 carry out the distribution and collection of water circulating in the heating and hot water supply.

Installation of heating and hot water works as follows.

Mine water from the sump of column 1 enter for cleaning in the filter 2, and then into the evaporator of the heat pump 3. In the evaporator 3 by the heat of the mine water is the refrigerant, mine is water cooled and served in the drain water. A pair of refrigerant to enter the compressor 5, which is compressed to high pressure, which is determined by the condensation temperature tkcompressed refrigerant vapor and sent in one of the cavities of the capacitor 4. In the condenser 4 in the other cavity is fed by the circulation pump 9 network water, under the influence of which the condensation of the refrigerant, and released at kondev condenser 4, water enters the distribution manifold valve 11, and then into the heating system 7 and heater 8 hot water systems. The liquid refrigerant from the condenser 4 passes through the regulating valve 6, partially evaporates, cools up to evaporation temperature t0and enters the evaporator 3. Waste water from heating systems and hot water through a combined comb 12 is supplied to the inlet of the circulating pump 9, and then into one of the cavities of the capacitor 4 of the heat pump. For the smooth operation of installation provides for a backup filter. A dirty filter switch off, plug in the backup filter, and a dirty filter is washed with a reverse flow of clean water. The dirty water after washing the filter is drained into the sewer.

Proposed installation of heating and hot water, in which the low-potential source is used, the heat of mine waters, will abandon the construction and operation of heat networks of considerable length, will significantly reduce the cost of heat, the cost of fossil fuels for heating and hot water (fossil fuel will be consumed only on virobot the load on the environment. It should be noted that in the mining industry in the reservoirs is reset billion m3warm mine water. All this will give a significant socio-economic effect.

The proposed installation can be used for heating and hot water supply of buildings located at large distances from the Central thermal points requiring long strip of piping for heating and hot water. In addition, calculations show that the conversion efficiency of the heat pump when the temperature of the mine water 12oC is 3.3, i.e. 1 kWh of energy required to drive the heat pump, is obtained 3,3 kWh useful recycled energy. The annual savings in operating costs for heating and hot water for the mine with the mine water inflow 300-400 m3per hour will be more than 500 thousand rubles
