Description
Technical field
The present invention relates to air-conditioning technique, particularly can strengthen the drip tray structure of the outer machine of dual-circulation single of heat exchange efficiency.
Background technology
Air-conditioner is a kind of electrical Household appliance of indoor temperature being regulated and remained on the required situation of user, mainly is made of coolant circulating system and air circulation system.Carry out heat exchange to realize room temperature lowering or intensification, for people provide fresh, comfortable indoor air environment by the refrigerant and the indoor flow air that in coolant circulating system, circulate.Except common refrigerating/heating function, air-conditioner also has concurrently and becomes clean air after the indoor air filtration that will suck purifies and be discharged into the indoor air purifying function again, and is discharged into indoor dehumidification function again after the humid air that sucks become dry air.
The coolant circulating system of air-conditioner mainly is made up of compressor, reversal valve, heat exchanger and choke valve etc., and air circulation system is made up of inlet and outlet, air cleaner, fan and fan electromotor etc.The coolant circulating system of air-conditioner and the operation of air circulation system are controlled by electrical apparatus control system, control refrigeration, the operation that heats or dehumidify, and carry out room temperature setting and wind speed control etc.
Air-conditioner is broadly divided into package AC plant and detachable air conditioner.Package AC plant power is less and all parts all are contained in the casing, is installed in indoor and outdoor junction, as is installed in the window air conditioner on the room window.In the place of the more high-power air conditioning of needs, detachable air conditioner is installed generally.
Detachable air conditioner is made up of the indoor set and the off-premises station that separate, as wall-hanging, cabinet air conditioner etc.The heat exchanger of evaporimeter and condenser effect has been set respectively in indoor set and off-premises station.Conduit in evaporimeter and condenser the circulation of refrigerant by connecting between indoor set and the off-premises station, and carry out heat exchange circulation is with the refrigeration that realizes air-conditioner, operation heats or dehumidify.Air-conditioner refrigeration or the operation that heats state are adjusted the refrigerant flow direction by the action of control four-way change-over valve and are realized.
For example, air-conditioner is carrying out refrigerating state when operation, and refrigerant airborne heat in the absorption chamber in indoor heat exchanger becomes gaseous state by liquid state, after the compressed again machine compression, is become liquid to the outdoor heat of emitting in outdoor heat exchanger by gaseous state.Air-conditioner heats state when operation, and refrigerant heat in the absorption chamber outer air in outdoor heat exchanger becomes gaseous state by liquid state, after the compressed again machine compression, in indoor heat exchanger by the gaseous state liquefy, to the indoor heat of emitting.
Simultaneously, room air sucks indoor set from air inlet under the fan positive action, and is indoor by being flow back to by exhaust outlet after indoor heat exchanger cooling or the intensification again, promotes indoor adjustment by circulating of air.
In order to regulate room air, generally be: have indoor heat exchanger in inside of indoor installation, indoor fan, the indoor set of controller, has compressor in inside of outdoor mounted, fluid reservoir, outdoor heat exchanger, filter, choke valve, the off-premises station of outdoor fan, indoor set is connected with coolant piping with off-premises station, constitute coolant circulating system, but also have in order to save material, reduce cost, be convenient to make and be convenient to and install, two off-premises stations are attached together in a shell, make the outer machine detachable air conditioner of dual-circulation single, as shown in Figure 1, be the off-premises station stereogram of the outer machine detachable air conditioner of generally existing dual-circulation single, it by have water receiving groove 1 ' chassis 1; Closed assembly is in two outdoor heat exchangers 2,3 of chassis left rear side; Be installed on outdoor fan 4 (not shown)s on the chassis overhang of outdoor heat exchanger front; Be installed on two compressors 5,5 on the part of right side, chassis ' and be connected in fluid reservoir 6 (gas-liquid separator) between its inlet and loop pipe; Choke valve 7; Filter 8; Vertically be installed on the arc-shaped partition on the chassis 9 between compressor and outdoor heat exchanger and fan; The refrigerant pipe joint plate 10, front, the side panel (drawing) that vertically are installed on the right side, chassis, preceding, the side chassis constitute.
But: because two vertical closed assemblies of outdoor heat exchanger in the outer machine of general existing dual-circulation single are on left back sidepiece chassis, air-conditioner is at indoor heating, during outdoor cooling operation, freeze-out airborne water because of cooling on the top outdoor heat exchanger of its off-premises station just can be along the heat exchanger laminar flow on following outdoor heat exchanger, and then flow out in outdoor in the water receiving groove on the Heat exchanger sheet inflow chassis and through its pipe that leaks (drawing) under the edge, just water membrane is covered on the heat exchanger below making between the indoor heating on-stream period like this, influenced the heat exchange efficiency of following heat exchanger, also caused the inconsistent of two indoor set heat exchange efficiencies, this middle southern area in China is more outstanding.
Summary of the invention.
The present invention is in order to solve the problems referred to above that prior art exists, develop and disclose the drip tray structure of the outer machine of a kind of dual-circulation single, Heat exchanger sheet below the current direction that has condensed on the outdoor heat exchanger sheet above it has stoped in the outer machine of dual-circulation single, the back is flowed in the water receiving groove of chassis by the pipe that leaks again in the upper accepting water dish but flow into, and is flowed out in outdoor by the chassis water receiving groove pipe that leaks at last.
Realize that technical scheme of the present invention includes: the chassis with water receiving groove; Upper and lower vertical closed assembly is in two outdoor heat exchangers of chassis left rear side; Be installed on the outdoor fan on the chassis overhang of outdoor heat exchanger front; Be installed on two compressors on the part of right side, chassis and be connected in the fluid reservoir of its inlet; Choke valve; Filter; Vertically be installed on the arc-shaped partition on the chassis between compressor and outdoor heat exchanger and fan; Vertically be installed on refrigerant pipe joint plate, front and the side panel of the right side, chassis, preceding, side, it is characterized in that: also include with the side screw and the left side pipe that leaks and be spirally connected and be fixed in upper accepting water dish between upper and lower outdoor heat exchanger.
Its upper accepting water dish is corresponding with last heat exchanger horizontal cross-section, L-shaped being undertaken under the heat exchanger, and the width of its horizontal direction and length are greater than the width and the length of last heat exchanger horizontal direction.
The bottom left end design of its upper accepting water dish pipe that leaks, the pipe lower end that leaks is fixed on time heat exchanger and the chassis water receiving groove with pipe box, and the web upper design of upper accepting water dish has screw, is installed on upper and lower heat exchanger fixed mount and the arc-shaped partition screw with screw.
Advantage and good effect: drip tray structure of the present invention makes the outer machine of dual-circulation single heat circulation time, condensed water on the top Heat exchanger sheet flows in the upper accepting water dish, can not flow to down Heat exchanger sheet, so improved the heat exchange efficiency of time Heat exchanger sheet and corresponding air-conditioner thereof, made condensed water discharge more science and favourable.
