Description
Technical Field
The utility model relates to an air conditioning field especially relates to an improve air conditioning equipment of structure.
Background
The air conditioning equipment comprises an inner unit and an outer unit. The inner unit mainly comprises a shell, a fan, an inner heat exchanger, a copper connecting pipe with a refrigerant inside and the like. The external unit mainly comprises a shell, a fan, an external heat exchanger, a compressor and the like. The compressor is connected with the inner heat exchanger and the outer heat exchanger into a whole through a copper connecting pipe with a refrigerant inside, so that the refrigerant completes evaporation-condensation circulation, and the fan force the inner heat exchanger and the outer heat exchanger to exchange heat with the outside air through direct suction or blowing of the inner heat exchanger and the outer heat exchanger, thereby achieving the purpose of adjusting the temperature of the outside air.
An air conditioning apparatus having only a function of cooling an indoor temperature is constituted by: a compressor for compressing a refrigerant gas; an inner heat exchanger connected to the compressor through a pipe to perform a heat exchange between the air flowing along the pipe and the inner air; an expansion valve connected to the inner heat exchanger through a pipe to adjust a pressure of the gas flowing along the pipe; an outer heat exchanger installed outdoors and connected to the expansion valve through a pipe to exchange heat between the gas flowing along the pipe and the outside air; the pressure sensor is arranged in an outlet pipeline of the outer heat exchanger and used for measuring the outlet pressure of the outer heat exchanger and outputting an electric signal; the signal input end of the regulator is connected with the signal output end of the pressure sensor, and the signal output end of the regulator is connected with the input end of the fan; and the inner fan and the outer fan are used for forcibly exchanging heat for the inner heat exchanger and the outer heat exchanger respectively. When the air conditioning equipment has a heating function, a four-way valve is also arranged in the air conditioning equipment, and the compressor is respectively connected with the inner heat exchanger and the outer heat exchanger through the four-way valve. When heating the indoor, the four-way valve changes the circulation direction of the refrigerant gas, and at this time, the indoor becomes a condenser and the outdoor becomes an evaporator.
In the prior art, the magnitude of the outlet pressure of the outer heat exchanger is detected by a pressure sensor arranged in an outlet pipeline of the outer heat exchanger, so that the rotating speed of the outer fan is controlled timely. The principle is based on: the outlet pressure of the external heat exchanger has a corresponding relation with the temperature. The pressure sensor is used for detecting the pressure of the point to adjust the rotating speed rising edge and the rotating speed falling edge of the outer fan on the basis of the rated wind speed; when the pressure at the outlet of the outer heat exchanger is higher than a reference value, the pressure is high, the temperature is high, the regulator automatically increases the rotating speed of the outer fan to increase the forced convection air quantity, the condensation temperature is reduced during refrigeration, and the load of the compressor is reduced; when heating, the outer heat exchanger is an evaporator, the environment temperature is low, the evaporation temperature is lower, the heat exchanger is easy to frost, the regulator runs reversely at the moment, the lower the temperature is, the larger the convection air quantity is, the evaporation temperature is relatively increased, the return air temperature of the compressor is increased, the compressor is protected, the heating effect is enhanced, and the defrosting frequency is reduced.
The prior art has the following defects that for sub air-conditioning equipment, each individual unit or machine purposely limits the working environment (namely, adaptive working condition) in the design, but the unit or machine cannot be used completely according to the working environment given in the product specification in the actual use environment, the unit adaptive capacity can be stronger along with the difference of different use regions, seasons and temperature differences between morning and evening, but the unit compressor with fixed frequency and fixed length of capillary tubes can often work under the overload condition, so that the working life of the compressor can be shortened seriously. Just as the conditions of use and environment of the customer are not controllable, the manufacturer is likely to be out of reach of the current national air conditioner three pack standard.
Because the gas flow or the liquid flow in the heat exchanger is in a pulsating state, the pressure sensor works under a certain vibration frequency, and the pressure sensor generates a changed electric signal due to the deformation of different variables of the material caused by the pressure change, the material is easy to generate fatigue damage due to the long-term high-frequency working and the high-frequency vibration deformation of the material, and simultaneously, the performance parameters are easy to change, so that the output curve changes, the control precision is influenced, and even the normal work is influenced. Because the pressure sensor needs to be connected with a refrigerating system, one more interface increases a hidden danger of refrigerant leakage. In addition, the cost of the pressure sensor is also high.
