Abstract
An intelligent temp control method for the refrigerator with a single refrigerating circulation features that the temp control parameters can be automatically determined according to the variations of ambient temp, cold storage temp and refrigerating temp to control compressor and electric heater, resulting in optimal temp.
Description
Technical field
The invention belongs to tame electro-technical field, particularly a kind of refrigerator temperature control method.
Background technology
Current refrigerator often adopts the mode of many kind of refrigeration cycle to realize in order to reach more accurate temperature control, but for invariable frequency compressor, can both mate with compressor optimization owing to be difficult to accomplish each kind of refrigeration cycle, causes the refrigerator refrigerating efficiency not high, and energy-saving effect is bad.Single kind of refrigeration cycle refrigerator is because refrigeration system is mated through optimizing, and energy-saving effect is better.Prior art often adopts the mode of mechanical temperature controller to come the rough temperature of carrying out to control, and this mode exists the room temperature degree influenced by ambient temperature big, the problem that the fluctuation of room temperature degree is big.
Summary of the invention
The object of the invention is to provide a kind of refrigerator temperature control method of energy accurate temperature controlling.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: a kind of refrigerator temperature control method, on single kind of refrigeration cycle refrigerator: A, the refrigerating chamber duty is divided into several warm areas, different warm area startup-shutdown temperature differences are selected corresponding startup-shutdown temperature spot according to the startup-shutdown temperature spot of actual set gear correspondence; B, at the different warm areas of refrigerating chamber temperature-detecting device is set, the temperature signal that this checkout gear is obtained sends the refrigerator main control chip to; C, main control chip come current compressor and electrical heating are carried out break-make control by reading temperature signal; If D environment temperature or cabinet space temperature change, then control the also corresponding change of parameter.
Fix a temperature-detecting device on refrigerator evaporator, the temperature of this device of check is higher than certain specified temp point and just allows refrigeration before each refrigerating chamber refrigeration.
On refrigerator, install an ambient temperature detection device additional, along with the rising of environment temperature or reduce refrigerating chamber and the defrost temperature control point is opposed and should be changed.
On refrigerator, install the freezer temperature checkout gear additional, oppose and to change according to freezer temperature variation, refrigerating chamber and defrost temperature control point.
On the refrigerating chamber evaporation plate, install an electrical heating additional, in the certain hour of stopping process, open electrical heating, refrigerating chamber evaporation plate temperature is gone back up to rapidly more than the defrost control temperature.Simultaneously temperature of refrigerating chamber is carried out certain compensation.With the relation between balance refrigeration, the cryogenic temperature.
The present invention promptly realizes accurate temperature controlling by the monitoring of each chamber and environment temperature being controlled compressor and electrical heating on single kind of refrigeration cycle refrigerator.Not only energy-conservation, but also can reach and improve refrigerating capacity simultaneously.
Description of drawings
Fig. 1 is the refrigerator structure schematic diagram that utilizes the inventive method.
The specific embodiment
The refrigerator temperature control method comprises the steps
1, refrigerating chamber 1 and refrigerating chamber 9 duties are divided into several Control scope (startup-shutdown scope), select corresponding startup-shutdown temperature spot according to the actual set gear.
2, refrigerator is provided with temperature-detecting device (temperature sensor) 2,3,4,8, and the temperature signal that this checkout gear is obtained sends refrigerator main control chip 5 to;
3, read environment temperature and be divided into several sections by environment temperature sensor 2, determine current refrigerator startup-shutdown control parameter according to current environment temperature and design temperature scope.
4, refrigerator main control chip 5 comes current compressor 7 and electrical heating 6 are carried out break-make control by reading temperature signal and current gear.
If 5 environment temperatures change, main control chip is changed the temperature control parameter of corresponding startup-shutdown.
6, since refrigerating chamber 1 in refrigeration or not under the refrigerating state, the range of temperature of subregion has been crossed over freezing point, so before each refrigerating chamber 1 refrigeration, by the temperature on the sensor 4 inspection refrigerator evaporators, if be higher than some specified temps, think that the ice on the refrigerator evaporator melts fully, so just can freeze.
7, the temperature in the freezer temperature sensor 8 perception refrigerating chambers and the speed of variation, if it is higher that refrigerating chamber 9 temperature continue, then refrigerator control parameter is suitably revised, make refrigerating chamber 9 reach design temperature, remember the Correction and Control parameter simultaneously, adjust to optimum state so that when analogue occurring, will control temperature as early as possible.
If it is very fast that 8 refrigerating chambers, 9 temperature rise, then put into food in the possibility refrigerating chamber 9 into big calorimetric, at this moment system will control parameter and be adjusted to strong cold shelves, open 6 pairs of temperature of refrigerating chamber of electrical heating simultaneously and carry out suitable compensation, and refrigerating chamber 1 temperature is kept than stable status.Then withdraw from compensation behind refrigerating chamber 9 temperature stabilizations
If 9 environment temperatures are lower, then open electrical heating 6 and carry out temperature-compensating.Make under the satisfied situation of freezer temperature, it is low that refrigerating chamber was unlikely to.
This control strategy can satisfy the requirement of GB (GB8059.2) to refrigerator by a large amount of experiments fully under the situation of selecting suitable control parameter.
