Abstract
A large power modularized flexible vortex wind source heat pump machine set comprises a compressor, a chiller, a surface cooler and a thermal expansion valve, which are all connected with a four-way reversing valve, the compressor is a hermetic flexible scroll one, the chiller uses a tube heat exchanger of which the inner tubes are 3-8 groups of spiral tubes with a spiral shape, the chiller main tube is of a U type structure. The utility can avoid a liquid impact to the compressor, which is caused by a high refrigerant humidity, thereby prolonging the equipment service life, increasing the cooling(heating) capacity and improving the heat exchange effect.
Description
Affiliated technical field
The utility model relates to compression heat pump systems technology field.
Background technology
Air-hydro-thermal pump assembly is a kind of idle call heat pump that generally uses at present, and in this wind source heat pump, the cold-producing medium circulation power derives from compressor.For big capacity multiple pressure machine modularization wind source heat pump unit, compressor mostly is the semi-hermetic piston-type structure, this compressor reciprocating motion inertia is big, rotating speed can not be too high, capacity regulating realizes great-jump-forward classification adjusting by changing the working cylinder number, control characteristic under the sub-load is poor, and cold-producing medium causes liquid hammer easily, and it is short to influence service life.The heat exchange of wind source heat pump unit and cold (heat) matchmaker water is finished by freezing water apparatus, in high-power wind source heat pump unit, freezing water apparatus adopts shell and tube exchanger usually, its current are even inadequately, and heat transfer coefficient is little, and heat exchange efficiency is low, complex structure, increased equipment investment, the easy short circuit of cooling liquid has reduced heat-transfer effect.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, provides that a kind of refrigeration (heat) amount is big, the flexible vortex wind regime of the high-power modular source pump of good effect of heat exchange and long service life.
For achieving the above object, the technical solution adopted in the utility model is: it comprises base and the compressor and the freezing water apparatus that are installed on the base, surface cooler and heating power expansion valve are installed above compressor and freezing water apparatus, compressor, freezing water apparatus, surface cooler and heating power expansion valve all are connected with same four-way change-over valve, compressor adopts totally-enclosed flexible screw compressor, freezing water apparatus adopts double-tube heat exchanger, the interior pipe of double-tube heat exchanger is many helix tubes of 3-8 group of pencil in the shape of a spiral, and mother's pipe of freezing water apparatus is U type structure.
Adopt technique scheme, avoided compressor, improved service life of equipment because of the cold-producing medium high humidity causes liquid hammer.Big capacity double-tube heat exchanger is guaranteeing to have strengthened heat exchange area under the certain situation of refrigerant system resistance, thereby has improved refrigeration (heat) amount of unit.Shape is mobile in the shape of a spiral in shell for refrigerating medium, has certain perturbation action, makes laminar heat transfer become turbulent heat transfer.The screw shell that pipe in the spiral is equipped with in inside has improved resistance to deformation and the freeze proof ability of splitting.The mother of freezing water apparatus manages and adopts U type structure, makes each system's water yield distributed uniform, has improved the coefficient of heat transfer.

Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
In the embodiment shown in the figures, compressor 1, freezing water apparatus 2 and electrical control cubicles 6 are installed on the base 3 of the present utility model, by skeleton 5 surface cooler 4 and heating power expansion valve are installed above compressor 1 and freezing water apparatus 2, compressor 1, freezing water apparatus 2, surface cooler 4 and heating power expansion valve all are connected with same four-way change-over valve 9.Compressor 1 adopts totally-enclosed flexible screw compressor.Freezing water apparatus 2 adopts double-tube heat exchangers, and the interior pipe of double-tube heat exchanger be many helix tubes of 3-8 group of pencil in the shape of a spiral, and its helical angle is the 10-45 degree, constitute the axis of helix tube helical angle also be the 10-45 degree.The feed pipe 7 of freezing water apparatus 2 and the mother of return pipe 8 pipe are U type structure.Female pipe of return pipe 8 is connected on the outlet pipe of double-tube heat exchanger by quick adpting flange.
