Abstract
The invention pertains to the technical field of air conditioning, in particular to a setting arrangement and a method for temperature sensing of a commercial air conditioning. The setting arrangement comprises a keyboard inputting part; a temperature sensing part; a central micro processor part for calculation processing the signals input by keyboard inputting and the temperature sensing part; a part outputting the calculation results to the controlling circuit to control the compressor and the fan; a power supply circuit part. In order to get a room temperature near to actual temperature, the micro processor is designed with a calculation logic based on average values of the temperature at the air outlet of the indoor unit and the temperature sensed by the temperature sensor of the remote controller, so as to sense the average temperature to control the compressor. The method comprises: a user turning on the unit and sets the temperature and the run mode; refrigeration and heating starting; the temperature sensor at the air outlet and that of the remote controller sensing temperature; calculating the average of the two temperatures, and setting the temperature based on the average; judging whether the set temperature is reached; the refrigeration or heating stops if reaching the set temperature.
Description
Technical field
The present invention relates to air-conditioning technique, particularly commercial indoor set of air-conditioner temperature perception setting device and method.
Background technology
Air-conditioner is a kind of electrical installation of indoor temperature being regulated and remained on the required situation of user, mainly is made of 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.Except common refrigerating/heating function, air-conditioner is discharged into indoor dehumidification function after also having concurrently and becoming after the indoor air filtration that will suck purifies that clean air is discharged into the indoor air purifying function again and the humid air that sucks become dry air again.
The cooling cycle system of air-conditioner is made up of heat exchanger, reversal valve, compressor and throttling device etc., and air circulation system is made up of inlet and outlet, air guide, air filter, fan and fan electromotor etc.By remote controller input control order commander electrical apparatus control system, control is freezed, the operation that heats or dehumidify by the user for the cooling cycle system of air-conditioner and the operation of air circulation system, and carries out room temperature setting and wind speed control etc.
Air-conditioner generally can be 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-inserted etc. according to the set-up mode of indoor set.The heat exchanger of evaporimeter and condenser effect has been set respectively in indoor set and off-premises station.Cold-producing medium circulates in evaporimeter and condenser by the conduit that connects between indoor set and the off-premises station, and carries out heat exchange circulation, with the refrigeration that realizes air-conditioner, operation heats or dehumidify.Air-conditioner refrigeration or the change that heats state are adjusted the flow of refrigerant direction by the action of control four-way change-over valve and are realized.
As shown in Figure 1, commercial ceiling-inserted indoor apparatus of air conditioner embeds and is installed in the ceiling in hall, remote controller can be held in user's hand or hang on the wall, its two temperature sensors are installed in the air outlet and remote controller of indoor set, control to be provided with before operating at of compressor and electric fan dispatched from the factory according to the indoor temperature of which perception in the two and finish, its control program as shown in Figure 4, but in some big floor space, because remote controller is far away apart from its indoor set, can reach 30 meters as its distance of part model air-conditioner, therefore the room temperature difference of two temperature sensor perception is very big, so only the running of controlling compressor and electric fan according to the room temperature of certain temperature sensor perception has just produced problem, it is inaccurate that room air is regulated, thereby bring discomfort to the user, adjusting is made troubles to client again and is bothered repeatedly.
Summary of the invention.
The present invention is for solving the problems referred to above that exist in the existing air-conditioning technique, a kind of commercial indoor set of air-conditioner temperature perception setting device and method are provided, it can serve as according to adjusting cooler compressor and electric fan, reaching the required indoor preference temperature value of user fast with more approaching indoor actual temperature value.The inventive system comprises: the key input section of user instruction being set the input central processing unit; Air conditioner indoor set wind outlet temperature and remote controller place temperature are transferred to the temperature perception part of central microprocessor; The central microprocessor part that next signal carries out computing is partly failed in above-mentioned keyboard input, temperature perception; The computing result transported to control circuit and go to control the part of compressor and electric fan by control circuit; The power circuit part, it is characterized in that: when dispatching from the factory, be designed to mean value computation decision logic in order to obtain microprocessor in its indoor apparatus of air conditioner of more approaching actual room temperature, be used as controlling the foundation of compressor, electric fan running with computation of mean values according to air conditioner indoor set wind outlet and remote controller temperature sensor sense temperature.
Insert two interfaces of central microprocessor CPU behind air outlet temperature sensor, remote controller temperature sensor and the electric resistance partial pressure, filter capacitor in parallel between two temperature sensors and ground.
Its method includes: client or user begin design temperature and operation mode stage; The cooling and warming phase run; Air outlet and remote controller TEMP actuator temperature perception stage; The mean value computation of two temperature and according to its design temperature stage; Reach the not judgement stage of design temperature; If do not reach design temperature then return and continue refrigeration or heat running, if reach design temperature then stop refrigeration or heat phase run.
Advantage and good effect: commercial indoor set of air-conditioner temperature perception setting device of the present invention and method, after the user selects to set operation mode, air conditioner indoor set wind outlet temperature sensor sense temperature and remote controller place sense temperature are increased the mean value computation logic, the indoor temperature of judging more approaching reality is also controlled compressor based on this, electric fan is adjusted setting, improved the temperature control accuracy, reduce the user and regulated and control the time, efficiently reach the indoor temperature of customer requirements, also can reach purpose of energy saving simultaneously.
