By using the combination of the U-shaped heat exchanger and the axial fan, the indoor unit of the air conditioner increases the contact area of the heat exchanger and the circulating air, solves the problems of a cabinet air conditioner of the prior art, enhances the heat exchange capability of the heat exchanger, and improves the refrigerating capacity of the air conditioner.
Description
Technical field
The present invention relates to air-conditioner, particularly relate to the internal structure of air conditioner room unit.
Background technology
Air-conditioner is a kind of electrical installation of indoor temperature being regulated and remained on the required situation of user, mainly is made of cooling cycle system, air circulation system.Cooling cycle system comprises heat exchanger, compressor and throttling device, and the refrigerant that flows in the cooling cycle system and the moving air of heat exchanger outside carry out heat exchange, makes cooling of heat exchanger air outside or intensification.Air circulation system comprises fan and fan electromotor, air conducting passage, inlet and outlet, and air circulation system makes the air in the air-conditioner circulate promotion heat exchange and air temperature modification with the room air of air-conditioner outside.The cooling cycle system of air-conditioner and the operation of air circulation system are controlled by electrical apparatus control system, refrigerating/heating operation conversion, compressor operation and the room temperature setting and the wind speed control etc. of control air-conditioner.The air conditioning effect of air-conditioner is to be finished jointly by cooling cycle system and air circulation system, carry out the heating and cooling of room air and remain on the user temperature required, for people provide fresh, comfortable indoor air environment.
Air-conditioner is broadly divided into integral air conditioner and detachable air conditioner.
Integral air conditioner all is contained in all parts in the casing, is installed in indoor and outdoor junction, and the evaporimeter of heat exchanger and condenser are separately positioned in indoor and the outside part.As, window air conditioner is exactly a kind of integral air conditioner commonly used, is installed on the room window, from the air inlet inspiration room air of indoor, flow back to from the air outlet of indoor more afterwards by heat exchanger cooling (or intensification) indoor, to realize regulating the effect of indoor temperature.
Detachable air conditioner is formed by separating the indoor set and the off-premises station that are provided with and install, and heat exchanger is separately positioned in indoor set and the off-premises station as evaporimeter and condenser.Conduit circulation refrigerant by connecting between the heat exchanger of indoor set and off-premises station is so that carry out transfer of heat in refrigeration or heating operation.
Detachable air conditioner is by the installation site of its indoor set, can be divided into wall-hanging, suspension type and cabinet type etc.The indoor set of wall-hanging air conditioner hangs on the wall, and the suspension type indoor machine of air-conditioner is hung on the ceiling, and the indoor set of cabinet air conditioner is placed in the room on the ground.
Fig. 1 is the indoor machine structure of cabinet air-conditioner schematic diagram of prior art.
As shown in Figure 1, the outward appearance of cabinet type air conditioner indoor machine is the clothes closet shape, stand upright on the room keep to the side and by the window near, rectify generous clothes closet shape indoor set and can increase aesthetic feeling to the room.
The shell of air conditioner room unit is formed by the rear that the procapsid 1 of opening and the place ahead form opening and the back casing 2 that is fixed on the base 7 constitutes, procapsid 1 is made of the front panel 4 on top and the anterior lower panel 5 of bottom, and the front panel 4 and the anterior lower panel 5 of procapsid are buckled on the front openings of back casing 2.The both sides of anterior lower panel 5 are provided with air inlet 6, and the end face of front panel 4 and two sides set out air port 3.
Be provided with indoor heat exchanger 8 and indoor fan 9 in the air conditioner room unit.Fig. 2 is provided with position view for indoor heat exchanger 8 and indoor fan 9.As shown in Figure 2, indoor heat exchanger 8 is a plate body, tiltedly is placed on the top in the indoor set housing, and place indoor fan 9 above, freeze or can play the effect of evaporimeter or condenser during heating operation at air-conditioner.Indoor fan 9 is a centrifugal fan, be arranged on indoor heat exchanger 8 below.
When air-conditioner carries out refrigerating operaton, be arranged on compressor in the off-premises station under rotor drives, refrigerant in the compresser cylinder is compressed, the HTHP gaseous coolant that from compressor, spues, through warm high-pressure liquid refrigerant in changing into after outdoor heat exchanger (condenser) heat release, become the low-temp low-pressure liquid refrigerants by expansion valve again, the outer circulating air of indoor heat exchanger 8 (evaporimeter) and heat exchanger of flowing through then carries out heat exchange and endothermic transition is the low-temp low-pressure gaseous coolant, then, enter compressor again and after newly being compressed into the HTHP gaseous coolant, in refrigeration system, carry out kind of refrigeration cycle along said sequence.
Room air circulates outside heat exchanger under indoor fan 9 positive actions, indoor heat exchanger 8 carries out heat exchange with flowing through, therefore, the contact area of the situation that circulates of room air and heat exchanger and moving air all is directly connected to the refrigerating capacity of air-conditioner under the fan positive action.
The indoor set of the cabinet air conditioner of above-mentioned prior art, heat exchanger is the plate body of oblique placement, the contact area that circulates air of heat exchanger and heat exchange is less, and, indoor fan adopts centrifugal fan, and wind speed profile is inhomogeneous, therefore, the exchange capability of heat deficiency of indoor set causes the refrigeration performance of air-conditioner to be restricted.
Summary of the invention
Indoor set at the cabinet air conditioner of above-mentioned prior art, the problem of the heat exchanger exchange capability of heat deficiency that exists, the performance of restriction air-conditioner refrigeration, the present invention has released a kind of indoor set of cabinet air conditioner of new structure, utilize the heat exchanger of " ㄈ " shape structure to combine with aerofoil fan, increase the contact area of heat exchanger and circulating air, and make wind speed profile even, improve the exchange capability of heat of heat exchanger.
Air conditioner room unit involved in the present invention is provided with heat exchanger and fan in the shell of cuboid.Heat exchanger is " ㄈ " shape structure, is made of the back side and two sides, is arranged on the indoor set bottom.Fan adopts aerofoil fan, be arranged on heat exchanger above.The indoor set air inlet is arranged on outer casing underpart, is separately positioned on the back side and the two sides of lower case.
The heat exchanger of " ㄈ " shape structure is adjacent with the air inlet of indoor set shell, and the back side of heat exchanger is corresponding with the back side and the two sides air inlet of indoor set shell respectively with two sides.Under the aerofoil fan positive action, the indoor circulation air from the indoor set outer casing underpart back side and two sides air inlet enter carries out heat exchange simultaneously on three faces of heat exchanger.Adopt the heat exchanger of " ㄈ " shape structure, increase the contact area of heat exchanger and circulating air, improve the exchange capability of heat of heat exchanger.
Air conditioner room unit involved in the present invention utilizes the heat exchanger of " ㄈ " shape structure to combine with aerofoil fan, overcomes the problem of the cabinet air conditioner existence of prior art, promotes the exchange capability of heat of heat exchanger, improves the refrigerating capacity of air-conditioner.
