Abstract

The utility model relates to a traditional single refrigerated split air conditioner, cooled and condensed water drop in an interior wall-hung evaporator is discharged directly outside through a plastic tube. The utility model changing waste into valuables: original useless water is led into an exterior cabinet (a compressor, an air cooling fin and a heat rejection fan) through a port and a concave-type flume with a plurality of holes which can hold water and sprinkle water arranged at the bottom; the concave-type flume is arranged at the upper end of a cooling fin and sprinkles the water evenly on the air cooling fins to help dispel with the drip as well as create a heat dissipation mechanism combining with water and air so as to improve heat exchange rate and realize distinct economic benefit of saving power as a result.

Description

A kind of innovative device that can make split-type air conditioner energy-conservation 20%

1, technical field:

The present invention is applied to the single-cooling type split-type air conditioner, belongs to the refrigeration radiating energy-saving field.

2, background technology:

The heat exchanger system of existing split-type air conditioner is made up of evaporimeter and condenser, indoor evaporator is used for heat absorption in the single-cooling type air-conditioner, outdoor condenser is used for heat release, though different its structures of both profiles are basic identical, are divided into by its structure and have fin to meet two kinds of formula and corrugated tube types; Room air conditioner adopts fin to meet the formula heat exchanger in the majority, the fin of heat exchanger mainly divides: formula is met in the crack, corrugated or flat three kinds, and the crack meets formula condenser effect best, multisection type evaporimeter in the detachable air conditioner chamber interior walls chamber on-hook of using can make indoor machine of air-conditioner save 1/3 space than common air-conditioning device now, it is inner screw thread copper pipe and the aluminium foil corrugated fin that adopts economic unique process for machining and manufacturing to make, make cold-producing medium mobile faster in pipe, reduce energy loss, it is to press decorative pattern on copper strips for " weldering is by interior line coil pipe " to have improved heat exchanger U type pipe, be rolled into tubular again, be rolled into coil pipe through HFI welding, it is about 1/4 that heat exchange efficiency is improved, and this shows that on technology innovation makes that energy-conservation to become feasible be indubitable.But it is air-cooled that the used heat release of outdoor condenser is generally adopted, and its effect is desirable not to the utmost.

A, evaporimeter: be to absorb thermal component on the refrigeration system, claim that again " low-temperature receiver " is the heat exchanger that produces refrigerating capacity, its refrigerant liquid after capillary (or expansion valve) throttling is sprayed on and makes it the heat absorption vaporization in the evaporimeter, becomes the saturated vapor of low pressure.The cold-producing medium endothermic gasification constantly that flows forward finally all becomes saturated vapor, and saturated vapor continues heat absorption then, leaves evaporimeter after becoming superheated vapor, and the heating power of cold-producing medium changes and divides two zones in the evaporimeter; The front is the saturation state district, and temperature and pressure remains unchanged, and it takies most heat transfer area, and the back is that overheated zone (at the evaporator outlet end) only accounts for a small amount of heat transfer area.Avoid liquid hammer during the overheated favourable compressor air suction of steam.The heat that evaporimeter absorbs in air-conditioner from two partly; The one, cold moving air is emitted damp and hot, and the 2nd, emit latent heat during the condensation of water in air steam.

B, condenser: it is the heat release parts in the refrigeration system, and the high-temperature high-pressure gas refrigerant that compressor can be discharged dissipates its heat to condense after by the convection current of air becomes the high-temp liquid cold-producing medium, cold-producing medium condensation in condenser (heat release).Delivery temperature drops to condensation temperature the heat release starting stage after heat steam enters condenser, this moment, cold-producing medium became dry saturation vapor, this process only takies the sub-fraction heat transfer area of condenser, when flowing, dry saturation vapor is condensed into saturated liquid owing to heat release gradually in pipe, whole pressure process and temperature also remain unchanged, this is the main exothermic process in condensation, and most heat (latent heat) is discharged by this process, and it takies the most heat transfer area of condenser.Cold-producing medium in this process is gas, liquid two-phase and deposits, the terminal saturated liquid of condenser further is cooled, become subcooled liquid, pressure remains unchanged and temperature has reduced, this process also accounts for the little part heat transfer area of condenser, subcooled liquid is significant to refrigeration system, and it can make cold-producing medium not produce steam before entering capillary inlet (or expansion valve), and heat absorption improves refrigeration in the evaporimeter thereby more help spraying into after the throttling.

As if the above structural principle be perfect, but uncared-for is that evaporimeter is because saturated vapor continues heat absorption, the heat that evaporimeter absorbs is from two partly: emit latent heat during damp and hot and water in air steam condensation that the cooling air is emitted, it leads to flexible pipe and outdoor it is emitted to produce water droplet inevitably, in the technology of the present invention then be it is collected in the groove dish and will puts be used for outside the cooling system of cabinet-type air conditioner to make auxiliary water colod-application, this not only can not make troubles to construction sector---it must install water conservancy diversion earthing pipeline otherwise the overflow everywhere that is filled with water influence body of wall and downstairs the pedestrian dripped by spray to spatter, the more important thing is that every can reach water-white whitecap expense about 0.05～0.1 ton in 10 hours about water yields of work!

3, summary of the invention:

The utility model will be dealt with problems and is exactly: in order to the no water of draining it is used as water-cooling former after condensation in the damp-heat air of being emitted in the wall type on-hook evaporimeter of split-type air conditioner; its method is: install an interface (3) on outdoor cabinet-type air conditioner additional; guide on this interface by plastic tube (2) originally being used as the useless water that runs off in vain; and then receive a porous being installed additional above the cabinet-type air conditioner inner air fin can be for dripping on the spill gutter (4) that spills; spill by gathering to drip; can make original by increasing a water-cooling heat radiating device again on the basis that increases the fin area and utilize exhaust fan to dry the air-cooling apparatus that dispels the heat; reach further raising complete machine refrigeration so as to improving its heat radiation function; thereby minimizing power consumption; because meeting the formula fin by means of the fin that increases area of dissipation originally is by scavenger fan heat to be taken away merely; and add after the water-cooled its radiating effect now will be more obvious; it is calculated that reference; whenever the heat radiation of dripping can be taken away 700 caloric heats; can also when the design exhaust fan, suitably reduce its efficiency (consumed power) so relatively and can save partly electric energy; it is compared with the air conditioner structure of existing background technology and needn't change too that macrostructure can obtain more desirable refrigeration; the autostop phenomenon takes place when simultaneously also avoiding high temperature---often because outdoor temperature high-pressure side fin and outdoor temperature difference up to more than 37 ° the time diminish; cause that heat gathers; make refrigerant produce high pressure and reach 300Par; cause the protective device tripping operation in the machine; compressor quits work automatically; this reason is because interior machine low pressure raises it to be freezed; rather than because air-conditioning is out of order; it is because temperature is equal to atmospheric temperature or contrast causes on the fin; at this moment exhaust fan is changeing but due to not dispelling the heat; therefore; if just relatively can improve rate of heat exchange, also improved service life and brought reasonable more and safety to compressor operating by water-cooling.
