Background technology
The serial air-conditioning internal machine of existing air-cooled ducted air conditioner (or the sky buries machine) adopts the mode vertical with the fan air-out direction to settle heat exchanger; The condensed water of air conditioner refrigerating generation influences air-conditioning heat exchange effect product like this; Simultaneously owing to exist air-out dead angle part to cause bigger air turbulence; Produce bigger fin Rack, water droplet blows out problem under the easy simultaneously generation high wind speed.In recent years, the efficiency of air-conditioning product and noise had become the focus that industry is paid close attention to.Therefore, how effectively to utilize the air-out characteristics of centrifugal fan, improve the exchange efficiency of heat exchanger and fan air-out; Simultaneously, utilize the relation of heat exchanger and fan, reduce the influence of condensed water, eliminate the noise that the fan air-out causes the heat exchanger vibrations to produce the air-conditioning air-out.This has become the technical problem that the present technique field needs to be resolved hurrily.
Summary of the invention
For solving the problem that prior art exists, the utility model provides a kind of air-cooled ducted air conditioner indoor set, can improve the exchange efficiency of heat exchanger and fan air-out, reduces the influence of condensed water to the air-conditioning air-out, eliminates the noise that the fan air-out causes the heat exchanger vibrations to produce.
The purpose of the utility model realizes through following technical scheme:
A kind of air-cooled ducted air conditioner indoor set; Comprise air inlet and air outlet, the interior heat exchanger of casing, centrifugal blower and volute of blower on casing, the casing; Said centrifugal blower and volute of blower are arranged on the end in the casing, and said air outlet is arranged on the other end of casing, and said heat exchanger is arranged between centrifugal blower and the air outlet; It is characterized in that the setting that recedes of described heat exchanger upper end, heat exchanger top is near the exhaust outlet on volute of blower top.
Improvement to technique scheme: the angle of said heat exchanger and casing bottom surface is 45 °-75 °.
Further improvement to technique scheme: described heat exchanger upper end is at least 10cm apart from the horizontal range of volute of blower exhaust outlet; Described heat exchanger lower end is at least 100cm apart from the horizontal range of volute of blower exhaust outlet.
A kind of improvement to technique scheme: described air inlet is set in place on the casing bottom surface of volute of blower below.
Another kind to technique scheme improves: described air inlet is arranged on the casing end face near the volute of blower rear portion.
Further improvement to technique scheme: described heat exchanger is a finned tube exchanger, and said finned tube exchanger is at least 2 rows.
The utility model compared with prior art has many advantages and good effect:
1, the utility model is arranged on the centrifugal fan front with the heat exchanger in the air-cooled ducted air conditioner indoor set casing, and heat exchanger recedes, and heat exchanger top is near the exhaust outlet on volute of blower top.The heat exchanger position is provided with rationally, can make the basically identical that flows to of wind direction and heat exchanger condensed water, accelerates to prevent water droplet when it flows and blows out problem, reduces the influence of condensed water to the air-conditioning air-out.Simultaneously, make eddy airstream away from heat exchanger, do not have eddy airstream to cause the heat exchanger vibrations, noise is low.Can improve the exchange efficiency of heat exchanger and fan air-out,
2, the utility model is simple in structure, is convenient to processing and fabricating, and cost is lower.
