The quick switching device of high/low temperature alternation of the present utility model, increase air-supply arrangement, in casing, room temperature is lowered the temperature to room air-supply in casing higher than during start-up temperature threshold values, thus when high temperature switches low temperature, if when in casing, room temperature has start-up temperature threshold values higher than refrigerating plant, air-supply arrangement accelerates room cooling in casing to room air-supply in casing, thus shorten refrigerating plant interval time start-up time, greatly can shorten the time from high temperature transformation to chilling process, having high/low temperature switches rapidly, the advantage that efficiency is high.
The utility model is set to further: described air-supply arrangement also has when high temperature shift to the intensification operating mode that room air-supply in casing heats up.
By adopting technique scheme, air-supply arrangement when low temperature is to high temperature shift, has the intensification operating mode of room air-supplyization ice in casing, effectively shortens the heating-up time simultaneously, improves the efficiency that low temperature switches to high temperature.
The utility model is set to further: be also provided with electric mounting compartment in described casing, the interior room of electric mounting compartment and casing is heat insulation, described air-supply arrangement includes forced-ventilated fan, the suction opeing of forced-ventilated fan is communicated with electric mounting compartment, the air outlet of forced-ventilated fan is provided with control valve, and control valve leads to room in described casing through tracheae.
By adopting technique scheme; electric mounting compartment is generally used for the electric equipments such as mounted motor; in it, temperature is generally the constant temperature of about 40 DEG C to about 50 DEG C; the forced-ventilated fan extracting of air-supply arrangement wherein air to room in casing; more be conducive to cooling and temperature rise effect; improve temperature switching efficiency; and for the parts of electric mounting compartment, there is cooling-down effect; play a protective role; the controlled valve of air outlet of forced-ventilated fan controls; open when needs are blown, realize forced-ventilated fan to room air-supply in casing.
This practicality is newly set to further: described control valve is magnetic valve, and magnetic valve is connected with the host computer driving it to open and close, and host computer is connected with temperature controller, and temperature controller is connected with temperature sensor, and described temperature controller connects refrigerating plant and heater.
By adopting technique scheme, realizing Based Intelligent Control, controlling more flexibility and reliability.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the quick switching device schematic diagram of the utility model specific embodiment high/low temperature alternation.
Detailed description of the invention
See accompanying drawing 1, the quick switching device of a kind of high/low temperature alternation disclosed in the utility model, comprise the casing 1 with interior room 11, freezing to room in casing 11 realizes the refrigerating plant 2 of low temperature conversion, and room in casing 11 is heated to the heater 3 realizing high temperature shift; Described refrigerating plant 2 has start-up temperature threshold values (being generally 80 DEG C), and refrigerating plant 2 starts below start-up temperature threshold values; Also include the air-supply arrangement 4 can blown to room in casing 11, air-supply arrangement 4 has in the casing room 11 temperature cooling operating mode higher than cooling of blowing to room in casing 11 during start-up temperature threshold values, and stops the off working state of blowing to room in casing 11 when refrigerating plant 2 starts.When high temperature in room in casing 11 is switched low temperature, if when in casing, room 11 temperature has start-up temperature threshold values higher than refrigerating plant 2, air-supply arrangement 4 is accelerated room 11 in casing to room in casing 11 air-supply and is lowered the temperature, thus shorten refrigerating plant 2 interval time start-up time, greatly can shorten the time from high temperature transformation to chilling process, having high/low temperature switches rapidly, the advantage that efficiency is high.And described air-supply arrangement 4 also has when high temperature shift to the intensification operating mode that room in casing 11 air-supply heats up.Air-supply arrangement 4 is simultaneously when low temperature is to high temperature shift, and in casing, room 11 air-supplyization ice, effectively shortens the heating-up time, improves the efficiency that low temperature switches to high temperature.
In this specific embodiment, electric mounting compartment 12 is also provided with in described casing 1, the interior room 11 heat insulation (directly can not carry out heat exchange) of electric mounting compartment 12 and casing 1, described air-supply arrangement 4 includes forced-ventilated fan 41, the suction opeing of forced-ventilated fan 41 is communicated with electric mounting compartment 12, the air outlet of forced-ventilated fan 41 is provided with control valve 42, and control valve 42 leads to room 11 in described casing 1 through tracheae 43.Electric mounting compartment is generally used for the electric equipments such as mounted motor; in it, temperature is generally the constant temperature of about 40 DEG C to about 50 DEG C; the forced-ventilated fan extracting of air-supply arrangement wherein air to room in casing; more be conducive to cooling and temperature rise effect, improve temperature switching efficiency, and for the parts of electric mounting compartment, there is cooling-down effect; play a protective role; the controlled valve of air outlet of forced-ventilated fan controls, and opens when needs are blown, and realizes forced-ventilated fan to room air-supply in casing.
