Description
Technical Field
The utility model relates to a frequency conversion scroll compressor of function is detected in area belongs to electronic scroll compressor technical field.
Background
The variable frequency air conditioner compressor has a variable frequency function within a certain range, so that the variable frequency air conditioner compressor has advantages in the aspects of air conditioner comfort and energy conservation, the frequency of a common compressor is controlled by an air conditioner controller, the air conditioner controller determines the operating frequency of the compressor according to the difference between the target temperature and the actual temperature, a control strategy of the air conditioner controller needs a large amount of test data for supporting, and the experience effect of a user is poor frequently. The automobile-used inverter compressor passively accepts the control signal of host computer, can't monitor air conditioning system's operating condition, can't in time carry out the protectiveness to the trouble that air conditioning system probably appears and shut down, often causes air conditioning compressor's damage, and on-off type air conditioner controller in addition, air conditioning system can't realize the frequency conversion operation.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the problem of how to make air conditioning system realize frequency conversion operation is solved.
In order to solve the technical problem, the utility model provides a frequency conversion scroll compressor of function is detected in area is provided, including the casing, be equipped with the compressor pump body and driving motor in the casing, the outside of casing is equipped with and is fixed with and driving motor connection director, and the outside of controller is equipped with the motor cover, its characterized in that, the controller be connected with the temperature pressure sensor's that is used for gathering the temperature of breathing in of compressor and suction pressure one end, temperature pressure sensor's the other end passes the casing and locates in the casing.
Preferably, the controller is a compressor controller ECU (electronic Control unit).
Preferably, the compressor controller ECU obtains values of a suction temperature and a suction pressure of the compressor through a temperature pressure sensor.
The utility model discloses an install the pressure temperature parameter that the pressure temperature sensor perception aspirated return circuit on the compressor body, scroll air condition compressor self possesses the ability of gathering air conditioning system key data, through compressor controller ECU's operation, and the operating frequency of adjusting the compressor initiatively can guarantee air conditioning system normal operating to the control strategy of host computer has been simplified.
The utility model discloses a value of suction pressure and suction temperature, compressor controller ECU can discover system defects such as pipeline jam, refrigerant leakage or condenser trouble and give alarm signal to the host computer to protection air conditioning system's normal operating.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model relates to a frequency conversion scroll compressor of function is detected in area, as shown in fig. 1, it includes the casing 1 of compressor, install the compressor pump body 5 and driving motor 6 in the casing 1, the electric appliance cover 3 is fixed the controller 2 in the periphery of casing 1, casing 1's the outside is equipped with promptly and is fixed with and driving motor 6 connection director 2, the outside of controller 2 is equipped with motor cover 3, controller 2 is connected with temperature pressure sensor 4's one end, temperature pressure sensor 4's the other end passes casing 1 and locates in the casing 1, controller 2 is compressor controller ECU, as shown in fig. 2, temperature pressure sensor 4's inductive signal input compressor controller ECU calculates and provides feedback signal for the air conditioning system controller.
After the air conditioning system for the vehicle is matched, the air suction temperature and the air suction pressure of the compressor in the air conditioning system can correspond to the temperature value of the air outlet of the air conditioner, the air suction temperature and the air suction pressure of the compressor are input to the compressor controller 2 in real time for operation, then the compressor can operate at the optimal frequency, the experience effect of a user is improved, and the purpose of energy conservation can be achieved.
The compressor controller ECU compares the acquired suction pressure and suction temperature with a "suction pressure-suction temperature" curve (obtained by experience and system matching test) in the ECU, as shown in fig. 3, where the abscissa is suction pressure and the ordinate is suction temperature, a region a in the graph represents a pressure working region at a reasonable working temperature, and a curve B represents a pressure working curve at an ideal working temperature, and when the temperature is higher than a maximum value corresponding to the graph, the rotation speed of the compressor is increased, otherwise, the rotation speed is decreased, so as to achieve the purpose of improving the experience effect of a user and saving energy. More importantly, after the two parameters exist, the compressor controller ECU can find system defects such as pipeline blockage, refrigerant leakage or condenser failure and the like and give an alarm signal to an upper computer, so that the normal operation of the air conditioning system is protected. For a simple air conditioner controller only with a switching signal and without a variable frequency signal, the compressor can realize an active variable frequency function.
