Problems solved by technology
[0003] Industrial refrigeration often needs to run continuously throughout the year, but because of the continuity of industrial production, even in winter when the outdoor temperature is very low, it is impossible to switch to free cooling, and the refrigerator can only be used for refrigeration all the time, causing great of energy waste
Individual factories want to use free cold source can only suspend the refrigerator, at the cost of sacrificing production continuity for free cooling switching, seriously affecting production efficiency

The invention provides a conversion device for a refrigerating machine and a free cold source. The conversion device is characterized in that an evaporator is in communication connection with a load device through a first communicating pipeline water outlet pipe and a first communicating pipeline water inlet pipe; a condenser is in communication connection with a cooling tower through a second communicating pipeline water outlet pipe and a second communicating pipeline water inlet pipe; the first communicating pipeline water outlet pipe is in communication connection with the second communicating pipeline water outlet pipe through a third communicating pipeline; the first communicating pipeline water inlet pipe is in communication connection with the second communicating pipeline water inlet pipe through a fourth communicating pipeline; and a third water pump is further arranged between the first communicating pipeline water outlet pipe and the first communicating pipeline water inlet pipe through a pipeline in a communicating manner. When the free cold source is enough to supply cold to the load device, a third electric valve is closed, a first electric valve and a second electric valve are opened, the load device and the cooling tower form a circulation loop for cooling, and when the refrigerating machine is completely unloaded, a second water pump and the third water pump are closed, so that energy consumption is reduced, and under the condition that equipment is not stopped, seamless switching between the refrigerating machine and the free cold source is realized.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator and a free cold source conversion device and a control method. Background technique [0002] China is a country short of energy, but also a big energy consumer. Rapid economic growth and urbanization pose serious challenges to energy supply and utilization. [0003] Industrial refrigeration often needs to run continuously throughout the year, but because of the continuity of industrial production, even when the outdoor temperature is very low in winter, it is impossible to switch to free cooling, and the refrigerator can only be used for refrigeration all the time, causing great of energy waste. Individual factories that want to use free cold sources can only suspend refrigerators, and switch between free cooling at the expense of production continuity, which seriously affects production efficiency. Contents of the invention [0004] The object of the pr...
