Description
Technical Field
The invention relates to the technical field of refrigerators, in particular to a refrigeration device and a refrigeration method for recycling condensed water.
Background
Chiller refrigeration systems (compression refrigeration) generally consist of four parts: compressor, condenser, throttle valve, evaporator. The working process is as follows: a low temperature, low pressure liquid refrigerant (e.g., freon) first absorbs heat from a high temperature heat source (e.g., ambient air) in an evaporator (e.g., an air conditioning unit) and vaporizes into a low pressure vapor. The refrigerant gas is then compressed in a compressor to a high temperature, high pressure vapor, which is cooled in a condenser by a low temperature heat source (e.g., cooling water) to condense into a high pressure liquid. And then throttled into low-temperature low-pressure liquid refrigerant by a throttling element (a capillary tube, a thermal expansion valve, an electronic expansion valve and the like). Thus completing a refrigeration cycle. The performance of heat pumps is generally evaluated by the coefficient of refrigeration (COP coefficient of performance).
When the existing condenser is used for condensing, because the space of a condensing cavity is large, and the position of an inlet pipeline and an outlet pipeline of the condensed water circulation is fixed, partial condensed water cannot enter the circulation when the condensed water is circularly condensed, so that the condensed water cannot be fully utilized, the condensing efficiency of the refrigerant is further reduced, and meanwhile, the positions of the heat exchange pipelines of the refrigerant in the condenser and the evaporator are fixed, so that the refrigerant in the condenser and the evaporator pipeline is low in heat exchange efficiency with the outside when the refrigerant is subjected to heat exchange, and the preparation efficiency of cold water is further reduced.
The invention patent with publication number CN116242047B discloses a refrigeration device with a circulating condensation function and a refrigeration method. Including the base, the base rigid coupling has the compressor, the base rigid coupling has the condensation jar, the inside rigid coupling of condensation jar has the condensation main section of thick bamboo, the condensation main section of thick bamboo rigid coupling and intercommunication have the condensation branch section of thick bamboo of circumference distribution, all the rigid coupling has circulating assembly between condensation main section of thick bamboo and the condensation branch section of thick bamboo of circumference distribution, set up condensing assembly in condensation main section of thick bamboo and the condensation branch section of thick bamboo, be provided with the reposition of redundant personnel subassembly in the condensing assembly, condensing assembly is provided with the switching-over subassembly, the base rigid coupling has the evaporation jar, through pipeline fixedly connected with expansion valve between condensation jar and the evaporation jar, and communicate each other between condensation jar, expansion valve and the evaporation jar, the evaporation jar is inside to be provided with the evaporating assembly. The condensation main cylinder and the condensation sub cylinder are matched to limit the flow state of the condensed water, so that the condensed water is ensured to exchange heat with the refrigerant sufficiently during the circulation period, the condensed water is circulated sufficiently, and the liquefaction efficiency of the refrigerant is improved.
However, the above prior art still has the following problems:
in the initial state of the working of the refrigerant, the low-temperature refrigerant in the condenser does not enter the evaporator yet, so that the temperature in the evaporator is higher in the initial state, the cooling burden of a condenser tube in the condenser is larger, the condenser tube cannot be cooled quickly in a short time, the initial refrigeration time is long, namely, the time for reaching the required refrigeration temperature is longer, and the time for generating cold water by the whole machine is longer;
in the condensation process, because the industrial heat transfer surface is usually a common metal material with high surface energy, water vapor appears in a membranous condensation shape, so that scale can be easily formed on the surfaces of the condensation main cylinder and the condensation sub cylinder, the scale can easily damage the condensation main cylinder and the condensation sub cylinder and greatly reduce the condensation effect, but the structural design of the condensation main cylinder and the condensation sub cylinder in the above-mentioned patent is complex, the processing cost is increased, and the condensation main cylinder and the condensation sub cylinder are inconvenient to take out from the condensation tank for cleaning;
