When the compressor 101 operates, the refrigeration equipment provided by the embodiment of the application controls the first heater 109 to be powered off; when the compressor 101 stops operating, the first heater 109 is de-energized or energized according to the set temperature of the first storage room, the measured temperature of the first storage room, the temperature of the first evaporator, and the external environment in which the refrigeration equipment is located.
Examples 1,
The embodiment of the present application provides a refrigeration apparatus, referring to fig. 2, the refrigeration apparatus includes a first compartment 300 and a second compartment 400 that are isolated from each other, a first evaporator 102, a first heater 109, a first storage compartment 301 and a first air duct 302 are disposed in the first compartment 300, cold energy generated by the first heater 109 is transmitted into the first storage compartment 301 through the first air duct 302, and the first heater 109 is configured to defrost the first evaporator 102; a second evaporator 104, a second heater 110, a second storage room 401 and a second air duct 402 are arranged in the second compartment 400, cold energy generated by the second heater 110 is transmitted into the second storage room 401 through the second air duct 402, and the second heater 110 is used for defrosting the second evaporator 104; a first air duct cover plate 111 is arranged between the first storage room 301 and the first air duct 302, a second air duct cover plate 112 is arranged between the second storage room 401 and the second air duct 402, the first evaporator 102 and the first heater 109 are positioned in the first air duct, the first heater 109 is positioned below the first evaporator 102, the second evaporator 104 and the second heater 110 are positioned in the second air duct 402, and the second heater 110 is positioned below the second evaporator 104; the first evaporator 102 is connected in series with the second evaporator 104; the refrigerant of the refrigeration apparatus flows through the first evaporator 102 and the second evaporator 104 in this order, and then returns to the return port of the compressor 101.
It should be noted that the first air duct 302 is separated from the first storage compartment 301 by a first air duct cover plate 111 with a heat preservation function, the first air duct cover plate 111, the first evaporator 102 and the first fan 103 form an air duct system of the first compartment 300, and an air outlet and an air inlet of the air duct system are both inside the first compartment 300; the second air duct 402 is separated from the second storage compartment 401 by a second air duct cover plate 112 with a heat preservation function, the second air duct cover plate 112, the second evaporator 104 and the second fan 105 form an air duct system of the second compartment 400, an air outlet and an air inlet of the air duct system are all arranged in the second compartment 400, no air duct is arranged between the first compartment 300 and the second compartment 400, and the first evaporator 102 and the second evaporator 104 are connected in series, so that the refrigeration system of the refrigeration equipment provided by the embodiment of the application is a single-system double-cycle system.
In the refrigeration apparatus provided by the embodiment of the present application, the first compartment 300 may be a cold storage functional compartment, and the second compartment 400 may be a cold storage functional compartment, and the first compartment 300 and the second compartment 400 are not communicated with each other, so that the problem of tainting odor between the two compartments can be solved. Since the first evaporator 102 and the second evaporator 104 are independent of each other and can be easily matched with the compressor 101, the refrigeration apparatus can set the temperature of the refrigerating function chamber to-10 ℃ or higher and the temperature of the freezing function chamber to 1 ℃ or lower.
Optionally, referring to fig. 3, the refrigeration device may further include a first sensor 113, a second sensor 114, a third sensor 115, a fourth sensor 116, and a fifth sensor 117, where the first sensor 113 is used for measuring the temperature of the first storage room 301, the second sensor 114 is used for measuring the temperature of the first evaporator 102, the third sensor 115 is used for measuring the temperature of the second storage room 401, the fourth sensor 116 is used for measuring the temperature of the second evaporator 104, and the fifth sensor 117 is used for measuring the external ambient temperature where the refrigeration device is located; the refrigeration device may further comprise a display means 500 which may be used to display the set temperature of the compartments.
Referring to fig. 2 and 3, the refrigeration apparatus may further include a control unit 200 for:
controlling the first heater 109 to be de-energized if the compressor 101 is operated; if the compressor 101 stops operating, the first heater 109 is controlled to be de-energized or energized based on the set temperature of the first storage room 301, the measured temperature of the first storage room 301, the temperature of the first evaporator 109, and the external ambient temperature at which the refrigeration apparatus is located.
Since the refrigerant flows from the first evaporator 102 to the second evaporator 104 and the temperature of the first evaporator 102 directly affects the evaporation process of the refrigerant, in order to prevent the temperature of the first evaporator 102 from rising back to affect the cooling state of the second evaporator 104, when the compressor 101 is running, the first heater 109 may be controlled to be powered off, so that the first evaporator 102 is in a low temperature state.
It should be noted that the second heater 110 may be powered off or powered on according to the operation time of the compressor 101, and when the accumulated operation time of the compressor 101 exceeds a preset value and the temperature of the second evaporator 104 is lower than the preset value, the second heater 110 is powered on to perform the defrosting operation of the first evaporator 104; when the temperature of the second evaporator 104 is higher than the preset value, the second heater 110 is controlled to be powered off in order to prevent the temperature of the second evaporator 104 from affecting the temperature of the second compartment 400.
Optionally, the control unit 200 may be specifically configured to: if the set temperature of the first storage room 301 is greater than 0 ℃, the external environment temperature of the refrigeration equipment is greater than a first preset value, and the actually measured temperature of the first storage room 301 is greater than 0 ℃; or, if the set temperature of the first storage room 301 is less than or equal to 0 ℃ and the external environment temperature of the refrigeration equipment is greater than the first preset value, controlling the first heater 109 to be powered off.
For example, the first preset value may be 15 ℃.
When the first heater 109 is powered on, in order to avoid the first heater 109 from being operated excessively due to temperature fluctuation of the first storage room 301 in the using process, the limitation of the ambient temperature is added to the operation of the first heater 109, when the external ambient temperature is too high, the first heater 109 is controlled to be powered off, and the temperature of the first storage room 301 can be prevented from being influenced by heat generated when the first heater 109 is powered on in a non-low-temperature environment; when the external environment temperature is higher and the measured temperature of the first storage room 301 is the set temperature, the first heater 109 is controlled to be powered off, so that the energy consumption can be reduced and the stability of the temperature of the first storage room 301 can be maintained.
For example, let the set temperature of the first storage room 301 be t1, the set temperature for start-up be t2, and the set temperature for shutdown be t3, where t2 is t1 +. DELTA.t, t3 is t 1-DELTA.t, and Δ t > 0 ℃. It should be noted that, since the temperature adjustment range of the first storage room 301 can reach below 0 ℃, if the set temperature of the first storage room 301 is greater than 0 ℃, when the first evaporator 102 works, the measured temperature of the first storage room 301 can be less than 0 ℃, wherein the shutdown set temperature of the first storage room 301 can be greater than 0 ℃ or less than 0 ℃.
Optionally, the control unit 200 may be specifically configured to:
if the set temperature of the first storage room 301 is greater than 0 ℃, the measured temperature of the first storage room 301 is less than or equal to 0 ℃, the temperature of the first evaporator 102 is less than or equal to a second preset value, and the measured temperature of the first storage room 301 is less than or equal to a third preset value, wherein the second preset value is less than the third preset value; or, if the external ambient temperature is less than or equal to the first preset value, the temperature of the first evaporator 102 is less than or equal to the second preset value, and the measured temperature of the first storage room 301 is less than or equal to the third preset value, the first heater 109 is controlled to be powered on.
Illustratively, the second preset value may be T3- Δ T, wherein, since the temperature in the first storage room 301 may cause the temperature in the room to fluctuate with the opening or closing of the door, when the temperature is in the (T3- Δ T, T3) interval, in order to prevent the first heater 109 from being de-energized and the energizing time interval from being too short, the state of the first heater 109 may be controlled to be consistent with the state before the temperature of the first evaporator 102 reaches T3- Δ T; the third preset value may be t 3.
It should be noted that, when the temperature of the first evaporator 102 is lower than the preset value and the temperature of the first storage room 301 is lower than the preset value, the first heater 109 may be controlled to be powered on, so as to prevent the first evaporator 102 from frosting, and also raise the temperature of the first storage room 301 to the set temperature, thereby ensuring the temperature stability of the first storage room 301.
Optionally, the control unit may be specifically configured to:
if the external environment temperature of the refrigeration equipment is less than or equal to a first preset value and the temperature of the first evaporator 102 is greater than or equal to a third preset value; or, if the set temperature of the first storage room 301 is greater than 0 ℃, the measured temperature of the first storage room 301 is less than or equal to 0 ℃ and the temperature of the first evaporator 102 is greater than or equal to the third preset value; or, if the external ambient temperature is less than or equal to the first preset value, the temperature of the first evaporator 102 is less than or equal to the second preset value, and the measured temperature is greater than or equal to the set temperature of the first storage compartment 301, controlling the first heater 109 to be powered off.
When the temperature of the first evaporator 102 is higher than the preset value or the temperature of the first storage room 301 reaches the set value, the first heater 109 may be controlled to be powered off, so as to prevent the temperature of the first evaporator 102 from continuously increasing and affecting the internal temperature of the first storage room 301.
According to the refrigeration equipment and the control method, when the first evaporator of the refrigeration equipment is defrosted, the power-off or power-on of the first heater is controlled according to the set temperature and the measured temperature of the first storage room, the temperature of the first evaporator and the external environment temperature of the refrigeration equipment, so that the function of the refrigeration equipment is not influenced, the energy consumption is reduced, and the temperature stability of a refrigeration room is kept.
