Embodiment Construction

[0012] See attached picture. In this embodiment, 7 is the condenser of the ice machine, 8 is the ice tray of the evaporator of the ice machine, and the refrigerant circulates in the circuit formed between the two, and 9 is a hot gas bypass valve, which transfers the hot gas generated by the condenser 7 Transport to the evaporator ice tray 8 again. In the traditional ice machine, the above-mentioned basically constitutes a complete ice machine, and the ice harvesting mainly relies on the hot gas bypass valve 9; in this embodiment, the hot gas bypass valve 9 only plays the role of assisting the ice harvesting , mainly rely on other parts of the machine.

[0013] This embodiment also has a multi-source load balancing heat pump unit, which includes a compressor 1, three heat exchangers 2, 3, 4, an electromagnetic four-way valve 5 and an expansion valve 6; the heat exchanger 2 is located between the compressor 1 and the electromagnetic Between the inflow ends of the four-way valv...

Abstract

The invention discloses an ice maker. The ice maker comprises a condenser, an evaporator and a multisource load self-balancing heat pump, wherein a refrigerant circularly flows in a pipeline between the condenser and the evaporator; the multisource load self-balancing heat pump is used for supplying stable circulating hot water and circulating cold water for a system; the cold water of the multisource load self-balancing heat pump is communicated with the condenser of the ice maker; and the hot water of the multisource load self-balancing heat pump is communicated with the evaporator of the ice maker. Circulating low-temperature water is used for the condensation side and ice-collecting can be guaranteed without limiting water quantity, so the ice maker has the advantages of stable working condition, stable ice yield in all the year round, shortened ice-collecting time, capacities of optimizing the design of a compressor and optimizing the efficiency of the system, reduction in liquid-returning probability and great improvement on reliability.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, in particular to an ice maker. Background technique [0002] The present invention is a relatively large ice maker, which is generally used in hotels, restaurants and other places where the amount of ice is relatively large. In these occasions, the ice production under rated power is the most important index to measure the performance of the ice maker. [0003] The traditional ice machine is a simple refrigerant circuit. The refrigerant is sucked by the compressor—compressed—exhausted—condensed (liquefied) and then reaches the throttle valve, and then in the evaporator at -10°C to - The low-temperature evaporation at 18°C ​​absorbs heat and vaporizes, so that water can condense into an ice layer on the surface of the evaporator. This process is called ice making. When the ice cube reaches the required thickness, the hot air discharged from the compressor is introduced into the evaporator c...
