Abstract
The utility model relates to a heat pump machine set, in particular to the two-stage compression high temperature heat source heat pump machine set adopting a low temperature heat source. The problem to be solved of the prior art is that: firstly, the machine set needs the high temperature heat source and can not use the low temperature heat source; secondly, the high temperature mixed working substance does not have a finished product, a plurality of different working substances on site need to be mixed to form a finished product, the property is difficult to master, both the performance and the reliability of the machine set are affected; in addition, the evaporation temperature is decreased and the efficiency of the machine set is reduced due to the adoption of a dry evaporator. The technical proposal adopted to solve the technical problem is as follows: the two-stage compression high temperature heat source heat pump machine set adopting the low temperature heat source is characterized in that a high pressure compressor is connected with a low pressure compressor, an evaporator, an A throttling gear, a dry filter, a middle cooler with a B throttling gear and a condenser by pipelines. The utility model can generate the high temperature hot water by adopting the low temperature heat source and has the evident effects of saving energy and protecting environment.
Description
Technical field: the utility model 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 in the utility model 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 that inner sleeve is arranged in the outer tube, and the B throttling arrangement is communicated with inner sleeve by pipeline one end, and the other end is communicated with outer tube, and the vapor outlet port pipe is communicated with outer tube, and the outer tube two ends are provided with shrouding.
The beneficial effect that the utility model and background technology comparison are had is: the utility model 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.Also have, adopt sleeve type structure to make simple structure, easy to make and with low cost.
Description of drawings: Fig. 1-the utility model overall structure schematic diagram.The structural representation of Fig. 2-the utility model intercooler part.Fig. 3 is the partial enlarged drawing of the A part of Fig. 2.
The specific embodiment, with reference to Fig. 1, Fig. 2, Fig. 3, 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 1 connects low pressure compressor 2, evaporimeter 3, A throttling arrangement 4, device for drying and filtering 5, the intercooler 6 that has B throttling arrangement 7 and condenser 8 by pipeline.Wherein, intercooler 6 is that inner sleeve 9 is arranged in the outer tube 12, and B throttling arrangement 7 is communicated with inner sleeve 9 by pipeline 10 1 ends, and the other end is communicated with outer tube 12, and vapor outlet port pipe 11 is communicated with outer tube 12, and outer tube 12 two ends are provided with shrouding 13.
