OnBe benchmark, the increasing degree t in every interval sets up a temperature section, up to greater than a fixing maximum temperature point T
MaxTill, working speed N1, the N2......N of the corresponding compressor of each temperature section
MaxRead in the master chip of refrigerator then by the internal temperature T of temperature sensor detection refrigerator, the control program that has pre-deposited the compressor variable frequency startup in the master chip program storage will mate and the corresponding compressor operating rotational speed N of temperature T automatically, control the rotating speed of compressor with this, and then realize the VFC of refrigerator.But this invention is that detected object carries out variable frequency adjustment according to the refrigerator temperature inside only, the various working environments of refrigerator are not done and taken all factors into consideration, can't guarantee effectively that refrigerator remains under the optimum Match state in various working conditions to work.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, provide a kind of, make refrigerator under various working, can both be operated in the frequency conversion refrigerator of optimum Match state by the refrigerator multi-aspect information is monitored.
Another object of the present invention is to provide a kind of control method that is applied to above-mentioned frequency conversion refrigerator.
Refrigerator of the present invention is to realize like this, it comprises refrigeration system, refrigeration system comprises compressor, chamber magnetic valve, chamber temp sensor and environment temperature sensor, they are connected with controller respectively, simultaneously, controller connects condensation temperature sensor, power sensor and suction temperature sensor.
Its middle chamber magnetic valve has 2 at least, and the chamber temp sensor corresponds to rare 2.At the refrigerator of three-temperature-zone, its chamber magnetic valve comprises refrigerating chamber magnetic valve, refrigerating chamber magnetic valve and temperature-changing chamber magnetic valve; Chamber temp sensor correspondence comprises freezer temperature sensor, refrigerator temperature sensor and temperature-changing chamber temperature sensor.
Frequency conversion refrigerator control method of the present invention comprises following job step:
(1). energising starts;
(2). chamber temp sensor detection chambers temperature, the result is reached controller, controller judges whether to meet the compressor start condition of setting:
If do not meet, then return step (2);
If meet, then start refrigeration enters next step;
(3). environment temperature sensor testing environment temperature, the result is reached controller, controller is selected corresponding work mode;
(4). condensation temperature sensor, power sensor and suction temperature sensor detect condensation temperature, compressor horsepower and suction temperature respectively, pass through suction temperature, and then can infer the overtemperature and the supercooling temperature of refrigerant, and all results are reached controller, controller judges whether testing result surpasses the limiting value that the relevant work pattern sets:
If do not transfinite, then return step (2);
If transfinite, then enter next step;
(5). chamber temp sensor detection chambers temperature, the result is reached controller, controller judges whether to reach the temperature value of setting:
If reach, then close the chamber magnetic valve, compressor quits work, and returns step (2);
If do not reach, then controller changes mode of operation, returns step (3).
At the three-temperature-zone refrigerator, above-mentioned steps (5) comprising: freezer temperature sensor, refrigerator temperature sensor and temperature-changing chamber temperature sensor detect the temperature of chamber separately respectively, the result is reached controller, and controller judges whether each chamber reaches the temperature value of setting separately:
If there is chamber to reach, then close its magnetic valve;
If all chamber reaches, then compressor stops refrigeration;
If there is chamber not reach, then controller changes mode of operation, returns step (3).
Adopting the present invention can guarantee effectively that refrigerator remains under the optimum Match state in various working conditions works, the intension of its optimum Match state is: 1. when observed temperature and design temperature differ big, be control purpose matching system with the maximum cooling capacity; 2. taking into account energy-conservation during the maintenance temperature is to control the purpose matching system with temperature constant.
Description of drawings
Fig. 1 is a workflow diagram of the present invention.
The specific embodiment
Refrigerator of the present invention, it comprises refrigeration system, and refrigeration system comprises compressor, chamber magnetic valve, chamber temp sensor and environment temperature sensor, and they are connected with controller respectively, simultaneously, controller connects condensation temperature sensor, power sensor and suction temperature sensor.With the three-temperature-zone refrigerator is example, and its middle chamber magnetic valve comprises refrigerating chamber magnetic valve, refrigerating chamber magnetic valve and temperature-changing chamber magnetic valve; Chamber temp sensor correspondence comprises freezer temperature sensor, refrigerator temperature sensor and temperature-changing chamber temperature sensor.
Referring to Fig. 1, the control method of above-mentioned refrigerator comprises the steps:
(1). the refrigerator energising starts;
(2). chamber temp sensor detection chambers temperature, the result is reached controller, controller judges whether to meet the compressor start condition of setting:
If do not meet, then return step (2);
If meet, then start refrigeration enters next step;
(3). environment temperature sensor testing environment temperature, the result is reached controller, controller is selected corresponding work mode, some kinds of mode of operations are determined by the parameter of following several respects, comprise: compressor rotary speed, the chamber magnetic valve number that need open, condensation temperature limits value, the Power Limitation value, parameters such as suction temperature limits value;
(4). condensation temperature sensor, power sensor and suction temperature sensor detect condensation temperature, compressor horsepower and suction temperature respectively, pass through suction temperature, and then can infer the overtemperature and the supercooling temperature of refrigerant, and all results are reached controller, controller judges whether testing result surpasses the limiting value that the relevant work pattern sets:
If do not transfinite, then return step (2);
If transfinite, then enter next step;
(5). freezer temperature sensor, refrigerator temperature sensor and temperature-changing chamber temperature sensor detect the temperature of chamber separately respectively, and the result is reached controller, and controller judges whether each chamber reaches the temperature value of setting separately:
