Description
Technical field
The present invention relates to air-conditioning technical field, particularly relate to a kind of off-premises station of air-conditioner.
Background technology
Air-conditioner is a kind of electrical installation of indoor temperature being regulated and remained on the required situation of user.The air conditioning effect of air-conditioner is finished jointly by cooling cycle 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 cold-producing medium and the indoor flow air that circulate in its refrigeration system.
The cooling cycle system of air-conditioner comprises heat exchanger, compressor and throttling device.Air circulation system comprises fan and fan electromotor, inlet and outlet and air filter.The cooling cycle system of air-conditioner and the operation of air circulation system are controlled by electrical apparatus control system, under the control of electrical apparatus control system, cold-producing medium in the air-conditioner cooling cycle system absorbs heat and heat release in the circulation of compression one condensation one throttling one evaporation, and carry out heat exchange with room air by the fan forced flow of air circulation system, to realize room temperature lowering or intensification.
Air-conditioner is broadly divided into package AC plant and detachable air conditioner.Package AC plant all is contained in all parts in the casing, is installed in indoor and outdoor junction, as is installed in the window air conditioner on the room window.
Detachable air conditioner is made up of the indoor set and the off-premises station that separate, can be divided into cabinet-type, wall-hanging and ceiling mounting type etc. according to the set-up mode of indoor set.The heat exchanger of evaporimeter or condenser effect has been set respectively in indoor set and off-premises station.Cold-producing medium circulates in evaporimeter and condenser by the tube connector between indoor set and the off-premises station and carries out the heat exchange circulation, moves with the refrigerating state operation that realizes air-conditioner or the state that heats.The action adjustment flow of refrigerant direction that the air-conditioner refrigeration or the state that heats move by the control four-way change-over valve realizes.Air-conditioner carries out refrigerating state when operation, and cold-producing medium airborne heat in the absorption chamber in indoor heat exchanger becomes gaseous state by liquid state, after the compressed again machine compression, in outdoor heat exchanger by the gaseous state liquefy to the outdoor heat of emitting.Air-conditioner heats state operation, and cold-producing medium 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.
Fig. 1 is the external structure stereogram of a kind of air-conditioner outdoor unit of prior art, and Fig. 2 is the structural perspective that the prior art air-conditioner outdoor unit of front panel is not installed.As shown in Figure 1 and Figure 2, the air-conditioner outdoor unit of this prior art mainly comprises: constitute off-premises station front/rear end and two lateral outer structures, and front end face is provided with air discharge grille 1, and rear end face is provided with the shell body 4 of a plurality of not shown air inlets; The chassis 5 that is arranged on the bottom of shell body 4 and each parts of off-premises station can be installed on it; At least one is arranged on top one side on chassis 5, the low-temp low-pressure gaseous coolant from off-premises station can be compressed into the compressor 6 of HTHP gaseous coolant; Be vertically set on the opposite side and the rear part edge place on chassis 5, the outdoor heat converter 2 that can make HTHP gaseous coolant and the outdoor air around it mobile in it carry out heat exchange from compressor 6; Be vertically set on the middle part on chassis 5, and the middle part is formed with the electric machine support 3 that motor is provided with the hole: motor is provided with in the hole on the electric machine support 3 in not shown being installed in, and can produce the fan electromotor of rotary power after connecting power supply; Link to each other with the output shaft of fan electromotor is anterior, thereby can rotate under the revolving force effect of fan electromotor, thereby air discharge grille 1 row of the air that extraneous air is drawn into the inside of shell body 4 and will carries out heat exchange with outdoor heat converter 2 from the air inlet on shell body 4 rear end faces from shell body 4 front end faces is to the outdoor fan 7 of the exterior space; Be vertically set between compressor 6 and outdoor heat converter 2 and the outdoor fan 7, be used to separate the baffle plate 8 that compressor 6 and outdoor heat converter 2 and outdoor fan 7 are provided with the space; And the top board 9 that is installed in shell body 4 upper ends.
But, when outdoor fan 7 operations, near the outdoor fan 7 air quantity skewness, be outdoor fan 7 back sides air quantity a little less than, and the air quantity around the outdoor fan 7 is stronger, thereby the air that can cause outdoor fan 7 to be blown can't carry out uniform heat exchange to outdoor heat converter 2, make that outdoor heat converter 2 heat exchange are inhomogeneous, badly influence the heat exchange efficiency of outdoor heat converter 2, cause unnecessary waste of energy, improved the use cost of air-conditioner, reduced the use experience of air-conditioner user air-conditioner.
Summary of the invention
In view of this, the off-premises station that the purpose of this invention is to provide a kind of air-conditioner, can be so that the air that outdoor fan blew can carry out uniform heat exchange to outdoor heat converter, improve the heat exchange efficiency of outdoor heat converter greatly, avoid unnecessary waste of energy, reduced the use cost of air-conditioner, improved the reliability of air-conditioner, and then strengthened the use experience of air-conditioner user to air-conditioner, have higher market application foreground.
For this reason, the invention provides a kind of off-premises station of air-conditioner, include shell body 4, be provided with outdoor heat converter 2 and outdoor fan 7 in the described shell body 4, the outside of described outdoor fan 7 is covered with a fan housing 10, the rear end face opening of described fan housing 10 and be connected with outdoor heat converter 2.
Preferably, described outdoor heat converter 2 vertically is positioned on the chassis 5 of described shell body 4 bottoms, and described outdoor fan 7 parallels with the rear end face of shell body 4.
Preferably, the shape size of described fan housing 10 is greater than the shape size of described outdoor fan 7.
Preferably, the front end face of described fan housing 10 has the air discharge grille 11 of a circle, correspondence is provided with an exhaust window 20 on the front end face of described shell body 4, the shape size of described air discharge grille 11 and the big or small corresponding coupling of the shape of described exhaust window 20, the top of described air discharge grille 11 is embedded in the described exhaust window 20 during installation.
By above technical scheme provided by the invention as seen, the off-premises station of air-conditioner provided by the invention, by be covered with a fan housing at outdoor fan, between fan housing and outdoor heat converter, form the air channel, described outdoor fan is arranged in this air channel, allow air that outdoor fan blew scope inner flow passage in the air channel, can be so that the air that outdoor fan blew realization be carried out uniform heat exchange to outdoor heat converter, improve the heat exchange efficiency of outdoor heat converter greatly, avoid unnecessary waste of energy, reduced the use cost of air-conditioner, improved the reliability of air-conditioner, and then strengthened the use experience of air-conditioner user to air-conditioner, have higher market application foreground.
In addition, in view of the heat exchange efficiency of outdoor heat converter is enhanced greatly, therefore can be when guaranteeing that outdoor heat converter has good heat exchange effect, correspondingly reduce the size of outdoor heat converter, thereby reduce the production cost of outdoor heat converter, and then reduce the production cost of whole air-conditioner, promote air-conditioner in people's productive life, extensively to popularize.
