Technical field
The utility model relates to the air-conditioning unit, is specially the special-purpose water source heat pump units of a kind of surface water.
Background technology
Traditional central air-conditioning unit has the handpiece Water Chilling Units of Air-Cooled Heat Pump Unit, boiler heating, and it is bigger that Air-Cooled Heat Pump Unit is influenced by outdoor temperature, and under heating condition, air source heat pump needs electric assistant heating, and power consumption is not energy-conservation, and the Energy Efficiency Ratio of unit is very low; This air-conditioning of handpiece Water Chilling Units of boiler heating needs electricity or fire coal, fuel oil, combustion gas etc. when heating, not energy-conservation equally, and fire coal, fuel oil, combustion gas etc. are serious to atmosphere pollution, and operating cost is quite high.
The also design under standard condition of the operating mode of traditional water resource heat pump, when as energy body being provided with surface water, the refrigerating capacity of unit and heating capacity can obviously descend, and exerting oneself of unit can be had a strong impact on.
The utility model content
The technical problem that the utility model solved is to provide a kind of surface water special-purpose water source heat pump units, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
The special-purpose water source heat pump units of a kind of surface water; Comprise switch board, compressor, shell and tube evaporator, shell and tube condenser and frame; Wherein compressor links to each other through copper pipe with shell and tube evaporator; Shell and tube evaporator links to each other through copper pipe with shell and tube condenser, and switch board is arranged on the next door of said unit, and said frame connects and supports entire equipment.
On the copper pipe that connects said shell and tube evaporator and shell and tube condenser, also be provided with heating power expansion valve, liquid-sighting glass, magnetic valve, device for drying and filtering and angle valve.
On described switch board, be provided with display screen, for full Chinese interface touch-screen, easy to operate; Described compressor adopts the semi-closed double-screw compressor, and this compressor possesses 3 sections or 4 segmentation capacity modulations or stepless capacity modulation continuously, and have noise low, operate steadily, efficient is high, fault advantage low, that be easy to safeguard.
Described shell and tube evaporator adopts two-sided strengthened heat exchange copper tube; Have longitudinal inner thread on the inwall of copper pipe; On the outer wall of copper pipe, have external screw thread; External screw thread is a longitudinal screw, is to simulate the heat exchange optimal design through computer to develop, and its heat exchange efficiency improves about 25% than traditional product.
The heat exchanger tube inner surface of described shell and tube condenser adopts " V " type threaded line and pie convexity, also has the groove of two symmetries, not only can increase heat exchange area; Strengthen turbulence effect; And its distinctive flute profile can also be when condensation, and further the thickness of attenuate refrigerant liquid level reduces thermal resistance; Under the surface tension effects that causes by the condensate film skewness and reduce average thermal resistance; Thereby make that " Gregoring " effect is stronger, heat flow density is increased significantly, thereby improve heat transfer coefficient; And the smooth passage of its groove formation, can reduce the pressure drop of high-velocity fluid in the pipe significantly, thereby make condenser structure compact, volume is little, reduces the internal system resistance, reaches the purpose that improves this utility model efficient.
The utility model adopts computer programming to carry out automation control in order to guarantee safe operation, has that high-low pressure protection, compressor electric motor phase shortage are reverse, a defencive function of discharge deficiency in overload, antifreeze and evaporimeter and the condenser.For preventing that compressor from burning motor because of overload, be provided with the cooling medium liquid spray apparatus in the suction side of compressor, when compressor temperature was too high, the spray refrigerant was to reduce the temperature of compressor, the protection compressor.
Beneficial effect: the utility model is simple in structure, and is easy to use, utilizes the low-phase energy of water bodys such as river, lake; Utilize heat pump principle, input is electric energy in a small amount, realizes the conversion of low-phase energy; Reach and not only can freeze but also can heat, the purpose of health hot water can also be provided simultaneously.Through shell and tube evaporator, shell and tube condenser, the optimization of matching with compressor, heating power expansion valve has realized " the big temperature difference; low discharge " operation; Reduced the conveying energy consumption of surface water water resource heat pump, and when water temperature was low to moderate 4 ℃ in the winter time, unit can move normally still.
