Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides a high integrated intelligent power module, be applied to in the air conditioner that has variable volume enthalpy-increasing compressor device, but variable volume enthalpy-increasing compressor device includes a plurality of compressors, still be provided with temperature sensor in the air conditioner usually, be used for with air conditioner remote controller, the communication module of communications such as cell-phone, for example, infrared sensor module, the WIFI module etc. and be used for acquireing the acquisition module of the operating parameter of air conditioner, this acquisition module can be the MCU of air conditioning indoor set, or the MCU of off-premises station etc., the acquisition module can be according to the temperature that temperature sensor detected, the user setting parameter that communication module acquireed etc, the rotational speed when acquireing the operation mode of current air conditioner and the operation of air conditioner, electric current, voltage isoparametric. The MCU of the indoor unit can control the air conditioner to operate in modes such as refrigeration and heating according to user setting parameters sent by the remote controller, and adjust the operating parameters of the air conditioner to be matched with the set temperature according to the set temperature of the user so as to meet the requirements of customers.
When the air conditioning system is in heating operation under the low temperature condition, because the outdoor environment temperature is low, the temperature difference between the evaporating temperature of the outdoor heat exchanger and the environment temperature is very small, so that the quantity of heat absorbed from the external environment is relatively small, a large quantity of refrigerants are accumulated in the outdoor heat exchanger and the gas-liquid separator, the air suction and exhaust quantity of the compressor is insufficient, and the heating quantity of the indoor unit is greatly reduced. At present, a system with enhanced vapor injection is adopted to improve the heating capacity, generally, a heat exchanger is used for obtaining a medium-pressure gaseous refrigerant which is used as injection gas of a main compressor of an outdoor unit, but the enthalpy value of the injection gas is lower, so that the enhanced vapor injection efficiency of an air conditioning system is lower. And, due to the limitation of noise, the maximum operating frequency of the compressor should not be too high, which undoubtedly limits the output capacity of the compressor, and thus the cooling and heating speed of the air conditioner is slow and the effect is poor. The air conditioner adopting the dual-rotor compressor consumes more electric energy during the operation of the compressor, and particularly when the load of the air conditioner is low, the power of the dual-rotor compressor is relatively high, so that the energy efficiency ratio of the air conditioner is reduced.
In order to improve the energy efficiency of the air conditioner, a plurality of compressors, for example, two compressors, are arranged in the variable-capacity enthalpy-increasing compressor device of this embodiment, and the high-integration intelligent power module controls the corresponding number of IPM modules to operate, so as to drive the corresponding number of compressors to operate, meet the requirements for cooling/heating under different working conditions, and simultaneously, facilitate the improvement of the energy efficiency of the air conditioner. Referring to fig. 1 and 2, in an embodiment of the present invention, the high integrated smart power module includes:
the main controller 10 is configured to output a corresponding control signal according to an operation parameter of the air conditioner, where the operation parameter of the air conditioner includes an operation mode and an outdoor ambient temperature;
a plurality of compressor IPM modules 20, the number of said compressor IPM modules corresponding to the number of compressors of said variable capacity enthalpy increasing compressor arrangement; the controlled ends of the plurality of compressor IPM modules are connected to the control end of the main controller 10 one-to-one; and the plurality of compressor IPM modules are used for driving the corresponding compressors to work according to the control signal.
In this embodiment, the main controller 10 of the intelligent power module is integrated with a logic controller, a memory, a data processor, etc. and a software program and/or module stored in the memory and executable on the data processor, and the main controller 10 outputs a corresponding control signal to the compressor IPM module 20 of the intelligent power module by executing or executing the software program and/or module stored in the memory and calling the data stored in the memory, so that the compressor IPM module is driven according to the received control signal to drive the compressor to operate. The number of the compressor IPM modules 20 may be two or more, and for example, in a multi-split system in which a plurality of indoor units and a plurality of outdoor units are provided, the number of the compressor IPM modules 20 may be set according to the number of the outdoor units. The number of the compressor IPM modules 20 may be two or more, and the following embodiments are all described as examples. Correspondingly, when one compressor IPM module 20 works to drive one compressor in the variable capacity enthalpy-increasing compressor device 100 to work, at this time, the variable capacity enthalpy-increasing compressor device 100 can work as a single cylinder vapor injection enthalpy-increasing mode, or the compressor does not inject air, does not increase enthalpy, and the variable capacity enthalpy-increasing compressor device 100 works in a normal mode. When the two compressors in the variable-capacity enthalpy-increasing compressor device 100 are driven by the two compressor IPM modules 20 one to operate simultaneously, the variable-capacity enthalpy-increasing compressor device 100 operates in a double-cylinder enhanced vapor injection mode, that is, the two compressors operate simultaneously, so that the enhanced-enthalpy compressor enhanced vapor injection is enabled to operate simultaneously.
The main controller 10 may be connected to an MCU of an indoor unit of an air conditioner or an MCU of an outdoor unit of the air conditioner, and obtains operating parameters of the air conditioner through communication with the MCU, such as an indoor ambient temperature, an outdoor ambient temperature, a current operating speed of the compressor, an operating mode of the air conditioner, a system pressure of the air conditioner, and the like, which are obtained by the air conditioner. For example, in the heating mode, when the outdoor ambient temperature is low, or in the cooling mode, when the outdoor ambient temperature is high, both of these conditions result in a small temperature difference from the evaporating temperature of the outdoor heat exchanger. Referring to fig. 4, fig. 4 is a graph of energy efficiency/output capacity when a single compressor (single cylinder) and a plurality of compressors (double cylinders) work, and therefore, when the temperature difference is small, the load of the single compressor during work may be large, the output capacity cannot meet the operation requirement, the energy consumption of the air conditioner is large, the energy efficiency of the air conditioner is low, and the enthalpy value of the gaseous refrigerant in the compressor needs to be increased; when the temperature difference is large, the output capacity of a single compressor during working can meet the operation requirement, the energy efficiency is high, and the compressor can be controlled to operate in a conventional mode. According to the acquired operation parameters, the main controller 10 may establish a mapping relationship between the outdoor ambient temperature, the operation mode, and the control number of the compressor IPM modules 20 and store the mapping relationship. Therefore, when the air conditioner works, a corresponding control signal is output according to the acquired operation mode and the ambient temperature of the outdoor unit, and one compressor IPM module 20 is controlled to work, or two compressor IPM modules 20 are controlled to work simultaneously. It can be understood that, along with the change of the outdoor unit environment temperature, the number of the operating compressor IPM modules 20 may also be switched, for example, in a day, in an environment with a large day-night temperature difference, when the outdoor environment temperature is small in temperature difference with the evaporation temperature of the outdoor heat exchanger at night, a plurality of compressor IPM modules 20 operate simultaneously, and when the outdoor environment temperature is large in temperature difference with the evaporation temperature of the outdoor heat exchanger at day time, it may be switched to one compressor IPM module to operate independently.
In another embodiment, the main controller 10 may also be configured to operate based on control of an air conditioner indoor unit MCU, after the MCU outputs a corresponding control command according to the operation mode and the ambient temperature of the outdoor unit, the main controller 10 outputs a corresponding control signal according to the control command to control one compressor IPM module to operate, or to control a plurality of compressor IPM modules 20 to operate simultaneously. When one compressor IPM module is controlled to work, the compressor IPM module drives one compressor to work, at the moment, the compressor does not inject air and increases enthalpy, when a plurality of compressor IPM modules 20 are controlled to work, at the moment, the plurality of compressor IPM modules 20 respectively drive a plurality of compressors to work simultaneously, and at the moment, the compressor injects air and increases enthalpy.
The utility model discloses high integrated intelligent power module is through setting up main control unit 10 to the operation of the compressor IPM module that corresponds the number according to the operation mode of air conditioner and main control unit 10 control, thereby but the drive varactor increases enthalpy compressor arrangement 100 and starts or moves with conventional mode or jet enthalpy increasing mode, thereby realize the output of air conditioner big power so that indoor environment rapid heating up or rapid cooling, can also reduce the compressor vibration simultaneously, reduce the noise of air conditioner, realize the air conditioner low-power, the operation is imitated to the high energy, energy-concerving and environment-protective.
It should be noted that, in general, an air conditioner includes an indoor unit and an outdoor unit, and for an electric control board of the outdoor unit, an intelligent power module for driving a compressor, an intelligent power module for driving a fan, a main control module, a power module, and other functional modules are mostly disposed on the electric control board of the outdoor unit. These functional modules adopt the circuit module of discrete or partial integration to realize mostly, and the scattered each part of arranging at automatically controlled PCB board, but because automatically controlled board self structure, strong and weak electric isolation, prevent signal interference, heat dissipation etc. requirement, require the interval between each functional module to guarantee in safe distance for the automatically controlled board of off-premises station's volume is great, is unfavorable for the installation. Or disperse these on polylith circuit board, adopt the mode of wire jumper again to realize between main control module and other functional modules to and mutual electrical connection between each functional module, but the dispersion sets up each functional module and can lead to the wire jumper more and long, leads to electrical apparatus EMC performance to descend. And the electric control board of these two kinds of structures all can appear the device of electric control board more, lead to the assembly of off-premises station complicated, still can increase the manufacturing cost of air conditioner simultaneously, and the maintenance rate also can increase, is unfavorable for the stable use of air conditioner. More importantly, when the electric control board is realized by adopting a plurality of components, the energy consumption of the components is large, the heating is serious, the heat efficiency of the air conditioner is low, and the realization of energy conservation and emission reduction of the air conditioner is not facilitated.
In order to solve the problem, the utility model discloses an in main control unit 10 and a plurality of compressor IPM module 20 integration and a module, need not the wire and connect, can shorten the distance between main control unit 10 and the compressor IPM module, and reduce the wire jumper overlength and too much electromagnetic interference who arouses, in addition with above each functional module integration in the module, can improve the integrated level of integrated intelligent power module, realize a plurality of compressor drive integration, thereby reduce the volume of automatically controlled board, easy to assemble. Meanwhile, the components of the electric control board can be reduced, the PCB layout of the electric control board is simplified, and the production cost of the air conditioner is effectively reduced. The utility model discloses it is more still to have solved when automatically controlled board adopts a plurality of discrete components and parts to realize, and the problem that the assembly difficulty appears when leading to automatically controlled board to assemble electrical equipment to and the consumption of self is great, and it is also more serious to generate heat etc. leads to the thermal efficiency of air conditioner low, is unfavorable for the air conditioner to realize energy saving and emission reduction's problem.
Referring to fig. 1 and 2, in an embodiment, when the air conditioner is operated in a heating mode and the outdoor ambient temperature is less than a first preset temperature, the main controller 10 controls a plurality of the compressor IPM modules to simultaneously operate.
When the air conditioner operates in a cooling mode and the outdoor environment temperature is higher than a second preset temperature, the main controller 10 controls the plurality of compressor IPM modules to simultaneously operate, so that the variable-capacity enthalpy-increasing compressor device 100 is started in a double-cylinder enhanced vapor injection mode.
At the initial stage of the air conditioner start-up, the main controller 10 can control the plurality of compressor IPM modules 20 to work simultaneously according to the operation mode of the air conditioner and the outdoor environment temperature, thereby driving the variable capacity enthalpy-increasing compressor device 100 to start in a double-cylinder enhanced vapor injection mode, so as to realize the high-capacity output of the air conditioner, thereby enabling the indoor environment to be rapidly heated up or rapidly cooled down. In other embodiments, of course, when the air conditioner has a large load demand, the IPM modules of the compressor simultaneously operate to switch the operation mode of the variable capacity enthalpy-increasing compressor apparatus 100 to the dual-cylinder enhanced vapor injection mode, and when the air conditioner has a relatively low load, the operation mode of the variable capacity enthalpy-increasing compressor apparatus 100 may be switched to the single-cylinder enhanced vapor injection mode, so as to reduce energy consumption. Therefore, the utility model discloses a work of control compressor IPM module can improve the comfort level, and the fully provided user's demand can also realize energy saving and emission reduction. In this embodiment, the first preset temperature and the second preset temperature may be set according to the heat exchange capability of the heat exchanger of the air conditioner, and are not limited herein.

When the indoor environment temperature is lower than the user set temperature and the outdoor environment temperature is higher than or equal to a first preset temperature, the variable-capacity enthalpy-increasing compressor device 100 keeps the single-cylinder mode to operate by controlling one compressor IPM module to continuously work; when the indoor ambient temperature is lower than the user set temperature and the outdoor ambient temperature is lower than the first preset temperature, the plurality of compressor IPM modules 20 are controlled to simultaneously operate, so that the variable capacity enthalpy increasing compressor apparatus 100 operates in the dual cylinder mode.
