Abstract
The invention relates to a heat pump machine set, in particular to a two-grade compression high temperature water source heat pump machine set with the use of low temperature heat source. The invention aims at solving the problem of the prior art that firstly, the machine set needs to take use of high temperature heat source, but not low temperature heat source; secondly, high temperature mixing working substance has no finished goods and various working substances have to be mixed in site so that nature of the finished goods cannot be managed and performance and reliability of the machine set is affected; in addition, as a dry-type evaporator is adopted, evaporation temperature is low and efficiency of the machine set is reduced. The key points of the technical proposal adopted to solve the technical problem are as follows that the two-grade compression high temperature water source heat pump machine set with the use of low temperature heat source is characterized in that a high temperature compressor is connected with a low temperature compressor, an evaporator, an A throttling device, a drying filter, a middle cooler with a B throttling device and a condenser through a pipeline. The invention can be applied in production of high temperature hot water with the use of low temperature heat source and has the significant effect of energy saving and environmental protection, etc.
Description
Technical field: the present invention relates to a kind of source pump, particularly a kind of low-temperature heat source two stages of compression heat pump of high-temp water source unit that utilizes.
Background technology: the technical scheme that existing heat pump of high-temp water source is produced the unit of high-temperature-hot-water is: adopt a stage compressor to connect evaporimeter, throttling arrangement, device for drying and filtering and condenser by pipeline.Its existing problem is: at first unit need utilize high temperature heat source, and low-temperature heat source can't utilize; Secondly the high temperature mixed working fluid does not have finished product, needs the scene with multiple different working medium mixed preparing, and its character also is difficult to grasp, and has influence on the Performance And Reliability of unit; In addition, owing to can only adopt dry evaporator, its evaporating temperature is lower, has reduced the efficient of unit.
Summary of the invention: technical problem to be solved by this invention is exactly to exist in the background technology: at first unit need utilize high temperature heat source, and low-temperature heat source can't utilize; Secondly the high temperature mixed working fluid does not have finished product, needs the scene that multiple different working medium are mixed, and its character also is difficult to grasp, and has influence on the Performance And Reliability of unit; In addition, owing to can only adopt dry evaporator, its evaporating temperature is lower, has reduced the efficient of unit.Solving the problems of the technologies described above the technical scheme that is adopted is: a kind of two stages of compression heat pump of high-temp water source unit that utilizes low-temperature heat source is characterized in that high pressure compressor connects low pressure compressor, evaporimeter, A throttling arrangement, device for drying and filtering, the intercooler that has the B throttling arrangement and condenser by pipeline.Wherein, intercooler is to have in the cylindrical shell of end socket heat exchanger tube is set, and working medium is set on the intercooler imports and exports, and the B throttling arrangement is communicated with cylindrical shell by pipeline one end, and the import of other end connection heat exchanger tube also is provided with steam outlet pipe on the intercooler.
The beneficial effect that the present invention and background technology comparison are had is: the present invention adopts the technical scheme of above-mentioned two stages of compression, can utilize low-temperature heat source to produce high-temperature-hot-water, energy savings and environmental protection, unit rises to high condensing pressure by low evaporating pressure, pressure ratio can mean allocation, make each stage pressure than reducing, improve compressor gas transmission coefficient and displacement, thereby improve the efficient of unit, also improved the condition of work of compressor, improved the reliability of unit, this unit is except that adopting dry evaporator in addition, also can adopt flooded evaporator, improve unit efficiency.On the one hand, this unit can adopt single working medium again, need not on-the-spot prepare.
Description of drawings: Fig. 1-overall structure schematic diagram of the present invention.The structural representation of Fig. 2-intercooler part of the present invention.
The specific embodiment, with reference to Fig. 1, Fig. 2, a kind of two stages of compression heat pump of high-temp water source unit that utilizes low-temperature heat source, it is characterized in that high pressure compressor 1 connects low pressure compressor 2 by pipeline, evaporimeter 3, A throttling arrangement 4, device for drying and filtering 5, the intercooler 6 and the condenser 8 that have B throttling arrangement 7, intercooler 6 is to have in the cylindrical shell 11 of end socket 14 heat exchanger tube 13 is set, working medium is set on the intercooler 6 imports and exports 10, B throttling arrangement 7 is communicated with cylindrical shell 11 by pipeline 9 one ends, the other end is communicated with the import of heat exchanger tube 13, and steam outlet pipe 12 also is set on the intercooler 6.
