Abstract

The invention discloses an air-conditioner outdoor unit with a running-state sensing system for an outdoor unit fan. A pressure sensor is arranged on an exhaust grille and is connected to a circuit board of an outdoor control box. When an outdoor fan is abnormal in operation, the pressure sensor transmits signals of the circuit board of the outdoor control box to an indoor circuit board according to sensed wind pressure, so as to power off the indoor circuit board. The outdoor unit has the advantages that the wind pressure is sensed through the arrangement of the pressure sensor; once the fan stops running according to defrosting and heating overload logic, the indoor circuit board is powered off, and a compressor shuts down till the fan is maintained by personnel; till the pressure is recovered and the circuit board is powered on, the compressor starts to work again; and the outdoor unit can ensure that air conditioners are more convenient to maintain, and can strengthen the market competitiveness of air conditioner products.

Description

The air-conditioner outdoor unit that has outdoor machine fan operating state sensing system
Technical field
The present invention relates to a kind of air-conditioner, especially have the air-conditioner outdoor unit of outdoor machine fan operating state sensing system.
Background technology
Air-conditioner is a kind of device that makes its inner refrigerant carry out the refrigeration of being made up of compression process, condensation process, expansion process and evaporation process or heat circulation.When air-conditioner carries out kind of refrigeration cycle, the refrigerant that becomes high-temperature high-pressure state through compressor compresses can flow to condenser under the guiding of cross valve, and in condenser, dispel the heat to the outside, when flowing through expansion valve, significantly reduce its temperature and pressure then, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter subsequently, flow back in the compressor again through fluid reservoir at last.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.It is then opposite with above-mentioned kind of refrigeration cycle process to heat circulation.Air-conditioner is divided into domestic air conditioner and commercial use air conditioner usually.Wherein commercial use air conditioner is divided into wind pipe type and embedded two kinds, and it mainly is used in the buildings such as office building, market.
As shown in Figure 1, 2, the air-conditioner outdoor unit of prior art mainly comprises: constitute four sides of off-premises station, front end face is provided with air discharge grille 1, and rear end face is provided with the housing 4 of a plurality of air inlets; The chassis 5 that is arranged on the bottom of housing 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 can be compressed into the compressor 6 of HTHP gaseous coolant; The not shown rear part edge place that is arranged on chassis 5, the condenser that can make refrigerant mobile in it and its surrounding air carry out heat exchange; The not shown top that is arranged on 5 opposite side centres, chassis can produce the fan electromotor of rotary power after connecting power supply; Link to each other with the output shaft of fan electromotor, 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 housing 4 and will carries out heat exchange with condenser from the air inlet on housing 4 rear end faces from housing 4 front end faces is to the outdoor fan 7 of the exterior space; Be vertically set on the baffle plate 8 between compressor 6 and condenser and the outdoor fan 7; And extend and four edges 10 forming are formed by end face 9 with from end face 9 bending downwards, can be installed in the top cover 11 on housing 4 upper flanges.
As shown in Figure 3; when the air-conditioner outdoor unit of prior art turns round; compressor 6 starts, outdoor fan 7 runnings, fan of outdoor unit of air conditioner at present; there is not other control; if it is bad that fan occurs, when fan took place to shut down, compressor still remained in operation; must cause the action of overload of compressor protection switch, What is more causes compressor damage.
Summary of the invention
In order to address the above problem, the invention provides a kind of rotating speed, the air-conditioner outdoor unit that has outdoor machine fan operating state sensing system of control compressor operation according to outdoor fan.
In order to achieve the above object, a kind of air-conditioner outdoor unit that has outdoor machine fan operating state sensing system of the present invention comprises mainly constituting four sides of off-premises station that front end face is provided with air discharge grille, and rear end face is provided with the housing of a plurality of air inlets; The chassis that is arranged on lower part of frame and each parts of off-premises station can be installed on it; At least one is arranged on top one side on chassis, the low-temp low-pressure gaseous coolant can be compressed into the compressor of HTHP gaseous coolant; Be arranged on the rear part edge place on chassis, the condenser that can make refrigerant mobile in it and its surrounding air carry out heat exchange; Be arranged on the top in opposite side centre, chassis, after connecting power supply, can produce the fan electromotor of rotary power; Link to each other with the output shaft of fan electromotor, thereby can rotate under the revolving force effect of fan electromotor, thereby the air discharge grille row of the air that extraneous air is drawn into the inside of housing and will carries out heat exchange with condenser from the air inlet on the housing rear end face from the housing front end face is to the outdoor fan of the exterior space; On air discharge grille, also be provided with pressure sensor, pressure sensor is connected on the circuit board of outdoor control box, when outdoor fan turns round when unusual, pressure sensor passes to the interior circuit plate according to the blast of perception with the signal of the circuit board of outdoor control box, makes the outage of interior circuit plate.
Described pressure sensor is fixed on the air discharge grille by wire clip.
The invention has the beneficial effects as follows: by the design and installation pressure sensor; the perception blast, in case fan shut down, as the defrosting and the heating excess load logic; the outage of interior circuit plate; compressor shutdown after the personnel for the treatment of keep in repair, is recovered up to pressure; the circuit board power connection; compressor is just started working again, can make the more convenient maintenance of air-conditioning, can strengthen the product air-conditioning market competitiveness.
