Ice maker

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...

AI Technical Summary

Problems solved by technology

[0004] Since ice harvesting is realized by the hot gas bypass of the compressor, considering that the temperature of the hot gas cannot be too low during ice harvesting, the water volume of the water-cooled condenser in the water-cooled ice machine should be controlled to be small to improve the discharge of the compressor. Air pressure, so the system efficiency is low, and the hot gas bypass harvest time is also longer, which directly affects the 24-hour ice production and system efficiency
