Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, a heat source tower heat pump system of a combined ice making machine includes a heat source tower 1 and a heat pump unit 3, wherein the heat source tower 1 is provided with a liquid return port 14, a liquid outlet 13, an air inlet 11 and an air outlet 12, the air inlet 11 is used for outdoor air to enter the heat source tower 1 to exchange heat with an anti-freezing solution, and the air outlet 12 is used for discharging air in the heat source tower 1, which exchanges heat with the anti-freezing solution; the heat pump unit 3 is provided with a first evaporation channel and a first condensation channel, and the heat pump unit 3 is provided with a cold outlet 31 and a hot inlet 32 which are communicated with the first evaporation channel, and a cold inlet 33 and a hot outlet 34 which are communicated with the first condensation channel; an ice maker 2 is arranged between the heat source tower 1 and the heat pump unit 3, the ice maker 2 is provided with a second evaporation channel and a second condensation channel, the ice maker 2 is provided with a liquid inlet 21 and a concentrated liquid outlet 22 which are communicated with the second evaporation channel, a cold inlet 23 and a hot return port 24 which are communicated with the second condensation channel, the ice maker is provided with an ice removing port 25 and a water replenishing port 26, and the ice removing port 25 is used for removing ice blocks on the surface of an evaporator of the ice maker.
A liquid outlet 13 of the heat source tower 1 is connected with a liquid inlet 21 of the ice maker 2 through a pipeline, and a concentrated liquid outlet 22 of the ice maker 2 is connected with a liquid return port 14 of the heat source tower 1, so that an antifreezing solution condensation and concentration channel is formed; the cold outlet 31 of the heat pump unit 3 is connected with the cold inlet 23 of the ice maker 2 through a pipeline, the hot return port 24 of the ice maker 2 is connected with the hot inlet 32 of the heat pump unit 3 through a pipeline, and the cold inlet 33 and the hot outlet 34 of the heat pump unit 3 are respectively connected with the outlet and the inlet corresponding to the tail end of the user 4.
The adopted antifreezing solution is one of conventional antifreezing solutions such as calcium chloride solution, ethylene glycol solution and the like. The ice maker is composed of a compressor, an evaporator, a condenser and other components.
In the heat source tower, the air exchanges heat with the antifreezing solution, the air transfers heat to the antifreezing solution, so that the temperature of the antifreezing solution is raised, meanwhile, water molecules in the air enter the antifreezing solution to dilute the antifreezing solution, so that the freezing point of the antifreezing solution is raised, for example, the freezing point of the calcium chloride solution is-20 ℃, and the freezing point of the diluted calcium chloride solution is changed to-15 ℃.
After the anti-freezing solution enters the ice maker, in the ice making process of the ice maker, the compressor of the ice maker discharges high-temperature and high-pressure refrigerant steam into the condenser of the ice maker to be condensed into high-pressure liquid, then the high-pressure liquid is intercepted by the expansion valve of the ice maker to be changed into a low-temperature and low-pressure steam-liquid mixture, then the low-temperature and low-pressure gas enters the evaporator of the ice maker, the refrigerant in the evaporator of the ice maker absorbs the heat of the anti-freezing solution to be changed into low-.
During ice making circulation, the ice maker evaporator absorbs heat of the anti-freezing solution in the second evaporation channel, so that the temperature is reduced to about the freezing point temperature of the anti-freezing solution, at the moment, because the freezing point of water is high, the water absorbed by the anti-freezing solution from the air is quickly separated out, ice blocks are formed on the ice maker evaporator, the freezing point of the anti-freezing solution is low and cannot be separated out, the anti-freezing solution entering the ice maker is concentrated and is cooled at the same time, and then the low-temperature anti-freezing solution is formed and flows back to the heat source tower to continuously absorb the heat in the air. For example, the freezing point of the diluted calcium chloride solution is-15 ℃, the temperature is reduced to-15 ℃ to-20 ℃ by controlling an ice maker, and the water absorbed from the air is almost completely separated out. Because the amount of moisture absorbed by the antifreeze solution in the heat source tower is small, ice cubes in the ice maker can be regularly removed after the system is operated for a period of time.
During ice making circulation, the condenser of the ice maker condenses refrigerant steam into high-pressure liquid in the second condensation channel, a large amount of heat needs to be released, and then heat is transferred with cold air or cold water entering the ice maker by the heat pump unit, so that the cold air or the cold water is changed into air and water with higher temperature.
In the evaporation channel of the heat pump unit, the air and water with increased temperature entering the heat pump unit from the ice maker in the evaporation channel release heat, so that the temperature of the air and the water is reduced to be changed into cold air and cold water, and then the cold air and the cold water enter the ice maker to continuously absorb heat; in the condensation channel, cold air or cold water entering the heat pump unit from the end of a user absorbs heat and becomes high-temperature air and high-temperature water, so that the heating requirement of the end of the user is met.
The purpose of arranging the water replenishing port on the ice maker 2 is that when the heat source tower stops running, no anti-freezing solution enters the ice maker, so that the ice maker is easy to damage, and therefore, the ice maker can be effectively prevented from being damaged by replenishing water in time.
In specific implementation, a liquid supplementing port is arranged on the heat source tower and is used for supplementing and adding an anti-freezing solution solute.
In order to prevent the concentration of the antifreeze solution from lowering and causing the freezing point of the antifreeze solution to rise, the concentration of the antifreeze solution must be periodically measured, and the solute of the antifreeze solution must be added to make the concentration of the antifreeze solution appropriate.
In specific implementation, the ice maker is a water-cooling ice maker.
The adopted ice maker is a conventional water-cooling ice maker, and only the conventional water-cooling ice maker is filled with water to make ice, but the utility model discloses a filling in antifreeze solution.
Finally, it should be noted that the above-mentioned embodiments of the present invention are only examples for illustrating the present invention, and are not limitations to the embodiments of the present invention. Variations and modifications in other variations will occur to those skilled in the art upon reading the foregoing description. Not all embodiments are exhaustive.
