Abstract
The distributed water source heat pump and central heat supply technology is applied in a central heat supply system. In each of the heat exchange stations in the heat supply network, one or two water source heat pumps are installed and have the hot ends connected to water return pipeline in the primary side or secondary side so as to heat the returned water before the water enters the pipeline. The present invention can raise the energy efficiency of the system extremely and the heat supply safety and utilize geothermal resource in environment friendly mode. The water source heat pumps may be operated intermittently or continuously in raised economic performance. In addition, the present invention has also simple pipeline connection.
Description
Technical field:
The present invention is applied to the central heating technical field, exactly is the zone that is widely used in the cities and towns central heating, and water resource heat pump and central heating combined heat can greatly improve a kind of technology of systematic energy efficiency ratio.
Background technology:
The application of water resource heat pump is that the water at low temperature thermal source is increased to the high-temperature water thermal source at present, and the thermal source after the intensification is used for Winter heat supply etc.Because well-digging is restricted, its scale also is restricted; And the Energy Efficiency Ratio that produces is lower, generally about 3.5; When well or equipment break down, just can influence heat supply, the heat supply security is not high.
Summary of the invention:
The objective of the invention is by distributed water source heat pump and central heating combined heat,, still can realize heat supply separately, improved the security of heat supply by central heating system or water resource heat pump even guaranteed at the water source or equipment when breaking down; The technology of the present invention also can greatly improve the heating system Energy Efficiency Ratio.
The present invention is achieved through the following technical solutions: water resource heat pump can adopt two kinds of connected modes, a kind of is that hot junction with water resource heat pump is connected with the primary side return pipe, can the backwater of primary side be heated, water after the heating is sent into the water return pipeline of primary side again, make the energy be input to a submain net, get back to thermal source factory and be heated to the primary side supply water temperature again, be sent to each heat exchange station by the primary side water supply line; Another kind of mode is that the hot junction with water resource heat pump is connected with the secondary side return pipe, the secondary side backwater is once heated, water after the heating is sent into heat exchanger again and is carried out post bake, is heated to secondary side and supplies water temperature requiredly, is sent to hot user by the secondary side water supply line.Dual mode has all greatly improved the Energy Efficiency Ratio of heat supply.Be connected with the return piping of primary side (or secondary side) at each heat exchange station installation one cover or two cover water resource heat pumps, the heating load size does not influence heating quality, provides the part heat to get final product.
Advantage of the present invention: greatly improved the Energy Efficiency Ratio of heating system by distributed water source heat pump and central heating jointly-supplying technology, as often as possible obtained the energy in the water, utilized very geothermal energy resources and other water resource of environmental protection well; And when water resource heat pump or the arbitrary system of central heating break down, still can realize heat supply by another system in heat supply network or the heat pump, the heat supply security is guaranteed; Also can be according to actual needs, be interrupted or open water resource heat pump continuously, greatly improve the economy of system; All heat exchange stations all are equipped with a cover or two cover water resource heat pumps, and system can obtain very big heat, has saved fuel in a large number, has reduced the discharging of flue gases such as carbon dioxide and the discharging of lime-ash, is the effective means that reduces smoke contamination, not only environmental protection but also energy-conservation.
Description of drawings:
Figure is distributed water source heat pump and central heating jointly-supplying technology structural representation; Dotted line is water resource heat pump and secondary side return piping connected mode.
The specific embodiment:
Among the figure: 1, primary side water supply line; 6, heat exchanger;
2, primary side return piping; 7, secondary side water supply line;
3, water resource heat pump cold junction; 8, secondary side return piping;
4, water resource heat pump; 9, water source.
5, water resource heat pump hot junction;
A well and a cover or two cover water source heat pump units are installed in each heat exchange station of heat network system, Figure 1 shows that the hot junction (5) of water resource heat pump is connected with primary side backwater (2), realize the primary side backwater is heated; The hot junction (5) that Figure 2 shows that water resource heat pump is connected with secondary side backwater (8), realizes the heating to the secondary side backwater.
