Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
First the factor affecting temperature controller accuracy of temperature control is simply described below.
The accuracy of temperature control of temperature controller is subject to the impact of each side factors such as generating material, production technology and assembling, and specifically, the accuracy of temperature control of temperature controller is specifically by the impact of following factor:
1, material is produced.
For the production material of compression-type temperature controller itself, compression-type temperature controller is made according to the principle of expanding with heat and contract with cold, compression-type temperature controller makes contact be communicated with by the action promoting its internal lever or disconnects, and then realize temperature control, thus, compression-type temperature controller internals is produced the mechanical property of material and is directly connected to accuracy of temperature control, but after material property brings up to certain precision, will be difficult to continue raising.
For the production material of NTC electronic thermostat itself, NTC electronic thermostat is made according to the principle of thermistor, so the accuracy of temperature control of NTC electronic thermostat is directly affected by the material purity of thermistor itself.
2, production technology.
For the production technology of compression-type temperature controller itself, it is affect by the level of processing in production process that the machine work principle of compression-type temperature controller determines its accuracy of temperature control, if the various component processing precision of its inside are high, machine part action is smooth, then its accuracy of temperature control is high; Otherwise accuracy of temperature control is low.
3, assemble.
The tightness degree that the temperature-sensitive head of temperature controller contacts with controlled product structure affects accuracy of temperature control, and accuracy of temperature control is relevant with the assembling level of workman simultaneously.
Thus, compression-type temperature controller is difficult to improve accuracy of temperature control by the restriction of producing material, and NTC electronic thermostat is subject to the restriction of rigging error to be also difficult to improve accuracy of temperature control, thus the accuracy of temperature control of temperature controller is difficult to improve, and causes the accuracy of temperature control of associated refrigeration device cold water temperature to be also difficult to improve.
Based on this, the present invention proposes a kind of cold water temperature control method of refrigerating plant and a kind of refrigerating plant.
Below with reference to the accompanying drawings 1-5 describes cold water temperature control method and the refrigerating plant of the refrigerating plant of the embodiment of the present invention.
Fig. 1 is the cold water temperature control method flow chart of the refrigerating plant according to the embodiment of the present invention.As shown in Figure 1, the cold water temperature control method of this refrigerating plant comprises the following steps:
S1: control refrigerating plant and enter keeping warm mode.
S2: detect the water temperature in water tank in refrigerating plant.
S3: if water temperature is greater than the first preset temperature, then control refrigerating plant to carry out refrigerating operaton with Preset Time and be less than the second preset temperature to make water temperature, and after Preset Time, control refrigerating plant stopping refrigerating operaton, wherein, the second preset temperature is less than or equal to the first preset temperature.
That is, after refrigerating plant enters keeping warm mode, if no one's water, then control refrigerating plant and run in preset temperature interval, namely the water temperature controlled in water tank changes between the first preset temperature and the second preset temperature.
Needs are described, and according to conservation of energy principle, the energy variation that variations in temperature produces can be changed into the energy variation that time variations produces.Like this, same refrigerating plant is issued to identical preset temperature at same refrigerating environment, required cooling time is certain, thus, the running time of refrigerating operaton can be set when product development, make the water temperature in water tank reach preset temperature by the running time setting refrigerating operaton, thus avoid water temperature control accuracy to be subject to the impact of temperature controller various factors.
In refrigerating plant running, under keeping warm mode, the water temperature in water tank can be detected in real time, when water temperature is greater than the first preset temperature, control refrigerating plant and carry out refrigerating operaton by stopping refrigerating operaton switching to, enter set time control model, after operation Preset Time, control refrigerating plant and stop refrigerating operaton, the water temperature now in water tank will be less than the second preset temperature.More specifically, when water temperature is greater than the first preset temperature, can start compressor, refrigerating plant carries out refrigerating operaton, and controls compressor operating Preset Time, after compressor operating Preset Time, can close compressor, and refrigerating plant stops refrigerating operaton.
Like this, under keeping warm mode, the water temperature in water tank is remained on the second preset temperature.Wherein, second preset temperature can be less than the first preset temperature, thus high frequent can be avoided to start by arranging return difference (such as, return difference is the difference that the first preset temperature deducts the second preset temperature) and close, certain second preset temperature also can equal the first preset temperature.
The cold water temperature control method of the refrigerating plant of the embodiment of the present invention, under keeping warm mode, if the water temperature in water tank is greater than the first preset temperature, then controls refrigerating plant and carries out refrigerating operaton with Preset Time and be less than or equal to the second preset temperature to make water temperature.Thus, realize water temperature by Preset Time and control, thus can control the water temperature of cold water more accurately, water temperature and energy consumption temperature more, avoids the impact of temperature controller accuracy of temperature control.
According to one embodiment of present invention, as shown in Figure 2, when refrigerating plant runs first, control also to comprise before refrigerating plant enters keeping warm mode:
S10: control refrigerating plant and carry out refrigerating operaton.
S20: detect the water temperature in water tank.

That is, when refrigerating plant powers on first, control refrigerating plant and carry out refrigerating operaton, specifically can start compressor, detect the water temperature in water tank in real time, now can not consider the time, when water temperature is less than the second preset temperature, just control refrigerating plant and stop refrigerating operaton, specifically can close compressor, and control refrigerating plant and enter keeping warm mode.
According to another embodiment of the invention, as shown in Figure 3, when refrigerating plant runs first, control also to comprise before refrigerating plant enters keeping warm mode:
S100: detect the initial water temperature in water tank in refrigerating plant.
S200: according to initial water temperature determination initial operating time, and control refrigerating plant and carry out refrigerating operaton with initial operating time and be less than the second preset temperature to make the water temperature in water tank.
That is, when refrigerating plant powers on first, water temperature first in detection water tank is to obtain initial water temperature, then determine according to initial water temperature the running time and the initial operating time that carry out refrigerating operaton first, finally, control refrigerating plant and start to carry out refrigerating operaton, after operation initial operating time, control refrigerating plant and stop refrigerating operaton, the water temperature now in water tank will be less than the second preset temperature.More specifically, can compressor be started, control compressor operating initial operating time, after compressor operating initial operating time, can close compressor, refrigerating plant stops refrigerating operaton, and controls refrigerating plant and enter keeping warm mode.
Particularly, according to one embodiment of present invention, specifically comprise according to initial water temperature determination initial operating time: according to the difference determination initial operating time between gentle second preset temperature of initial water.
Wherein, it should be noted that, when the second preset temperature immobilizes, can only according to initial water temperature determination initial operating time, and the initial operating time that different initial water temperatures is corresponding different, can prestore the relation table between initial water temperature and initial operating time in refrigerating plant.When the second preset temperature can be set by the user, can only according to difference determination initial operating time, the initial operating time that different difference is corresponding different, can prestore the relation table between difference between gentle second preset temperature of initial water and initial operating time in refrigerating plant.
Further, according to still another embodiment of the invention, as shown in Figure 4, when refrigerating plant enter use water state time, the cold water temperature control method of refrigerating plant also comprises:
S4: detect the water temperature in water tank.
S5: if the water temperature in water tank is greater than the 3rd preset temperature, then control refrigerating plant and carry out refrigerating operaton, judge whether water temperature is less than the second preset temperature further, if, then control refrigerating plant and stop refrigerating operaton, and control refrigerating plant and enter keeping warm mode, wherein, the 3rd preset temperature is more than or equal to the first preset temperature.
That is, when user's water, cold water in water tank will flow out from the delivery port of refrigerating plant, refrigerating plant enters with water state, water temperature in water tank will with speed rising faster, when the water temperature in water tank rises to the 3rd preset temperature, compressor can be started, control refrigerating plant and carry out refrigerating operaton, and detect the water temperature in water tank in real time, this time not free restriction of refrigerating operaton, when water temperature is less than the second preset temperature, just control refrigerating plant and stop refrigerating operaton, close compressor, and control refrigerating plant and enter keeping warm mode.Certainly, if after user's use water terminates, the water temperature in water tank does not rise to the 3rd preset temperature, then directly control refrigerating plant and enter keeping warm mode.
