Description
Technical field
Heat pump air conditioner unit drip tray ice-melting structure, belongs to air-source cold water source pump apparatus field.
Background technology
The operation principle of air-source cold water source pump is that heat pump absorbs airborne low temperature heat energy come in, and is converted into high temperature heat after compressor compresses.But air source heat pump is in the cold area of Xia Redong, winter, outdoor temperature was conventionally between 5 DEG C ~-10 DEG C, and relative humidity is more than 60%, under this kind of operating mode simultaneously, the evaporating temperature of the refrigeration machine temperature that is often below the freezing point in air-source heat exchanger, malaria runs into cold surface exothermic process, and the easy surperficial frosting at heat exchanger, in the process of long-term work, frost layer constantly thickens, cause the thermal resistance of heat exchanger to increase, air duct stops up, and has a strong impact on the operating efficiency of whole system.
Particularly in the winter time, air-source cold water source pump is moved after a period of time under heating condition, the finned tube surface meeting frosting of air-side heat exchanger, and impact is conducted heat, so that heating capacity is more and more less, now can automatically convert cooling condition to.Compressor air-discharging directly enters air-side heat exchanger and defrosts, and after short-term is held frost, unit can convert again heating condition operation to.In the time of defrosting, the water producing when defrost can be dropped on the drip tray of finned tube below, and then this part water electrode easily freezes and cause discharging, therefore, be badly in need of now a kind of processing structure that can effectively prevent that defrosting water from freezing and this part defrosting water is thoroughly got rid of.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide one effectively to prevent that defrosting water from freezing, and discharges the heat pump air conditioner unit drip tray ice-melting structure of defrosting water smoothly.
The utility model solves the technical scheme that its technical problem adopts: this heat pump air conditioner unit drip tray ice-melting structure, comprise the gas piping and the liquid line that are arranged on the condensed water drip tray of finned heat exchanger bottom, are connected with finned heat exchanger, it is characterized in that: between described gas piping and liquid line, connect ice-melt coil pipe, the refrigerant of circulation HTHP in ice-melt coil pipe, ice-melt coil pipe along condensed water drip tray around steering wheel around finned heat exchanger bottom.
The defrosting water arrival end of described ice-melt coil pipe is fixedly connected with gas piping, and the defrosting water port of export is fixedly connected with liquid line.
Described ice-melt coil pipe is that diameter is the copper pipe of 4 ~ 6mm.Employing copper pipe is made, durable in use, is difficult for getting rusty, and has avoided the trouble of frequent replacing, and simple in structure, is easy to install fixing.
Described ice-melt coil pipe matches around length and angle of bend around length and angle of bend and condensed water drip tray inwall.The inwall of ice-melt coil pipe and condensed water drip tray is fitted more, be more conducive to defrosting water and flow out smoothly along ice-melt coil pipe.
Have prior art to compare, the beneficial effect that the utility model has is:
1, effectively prevent that defrosting water from freezing, discharge smoothly defrosting water: between gas piping and liquid line, connect ice-melt coil pipe, and by ice-melt coil pipe along condensed water drip tray around steering wheel around finned heat exchanger bottom, defrosting water can be along the smooth and easy discharge of the delivery port of condensed water drip tray, effectively avoid defrosting water to freeze in condensed water drip tray, neither affect refrigeration in summer, can ensure again the heating effect in winter.
2, ice-melt coil pipe adopts copper pipe, durable in use, is difficult for getting rusty, and has avoided the trouble of frequent replacing, and simple in structure, is easy to install fixing.
Brief description of the drawings
Fig. 1 is that heat pump air conditioner unit drip tray ice-melting structure is installed lateral side view schematic diagram.
Fig. 2 is front view schematic diagram after heat pump air conditioner unit drip tray ice-melting structure is installed.
Wherein: 1, casing 2, finned heat exchanger 3, gas piping 4, liquid line 5, condensed water drip tray 6, ice-melt coil pipe.
Detailed description of the invention
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model, is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
Attached Fig. 1 and 2 of reference: this heat pump air conditioner unit drip tray ice-melting structure, comprise the gas piping 3 and the liquid line 4 that are arranged on the condensed water drip tray 5 of finned heat exchanger 2 bottoms, are connected with finned heat exchanger 2, between gas piping 3 and liquid line 4, connect ice-melt coil pipe 6, the refrigerant of the interior circulation HTHP of ice-melt coil pipe 6, ice-melt coil pipe 6 along condensed water drip tray 5 around steering wheel around finned heat exchanger 2 bottoms.
The copper pipe that ice-melt coil pipe 6 is 4 ~ 6mm for diameter, the defrosting water arrival end of ice-melt coil pipe 6 is fixedly connected with gas piping 3, and the defrosting water port of export is fixedly connected with liquid line 4 tops.Ice-melt coil pipe 6 matches around length and angle of bend around length and angle of bend and condensed water drip tray 5 inwalls.
Operation principle and the course of work: when air-source cold water source pump heats defrost, four-way change-over valve commutation, the HTHP refrigerant of discharging through compressor enters finned heat exchanger and emits condensation heat, the frost on finned heat exchanger 2 surfaces is changed into water to be flow on condensed water drip tray 5, the water of falling in the time that environment temperature is lower on condensed water drip tray 5 can build-up ice, now, high temperature and high pressure gas in ice-melt coil pipe 6 can become water to flow out the ice-out on condensed water drip tray 5, high temperature and high pressure gas becomes highly pressurised liquid, after expansion valve reducing pressure by regulating flow, enter again case tube heat exchanger heat absorption, then enter compressor, after defrost, four-way change-over valve commutates and heats circulation.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
