Abstract
The utility model relates to a refrigerated counter with precooling equipment, which belongs to refrigeration equipment. The refrigerated counter comprises a counter body as well as a compressor, a condenser, a throttling device, an evaporator, and a precooling device which are arranged on the counter body. Because the precooling device is arranged between an air return opening of the counter and the evaporator, air to enter in the evaporator is carried out the dehumidifying treatment, the problem of overhigh humidity of the air entering into the evaporator is solved, thus the times of defrosting are decreased, the running efficiency of the evaporator is improved, and the refrigerating performance of the counter is further improved through reducing the temperature fluctuation of refrigerated foods.
Description
Technical field
The utility model relates to refrigeration plant, relates generally to a kind of refrigerator display case with pre-cooler.
Background technology
Advantages such as existing vertical open type food refrigerated display cabinet is elegant in appearance with it, the shopping that makes things convenient for customers, the desire to purchase that has stimulated client has widely obtained in the supermarket using widely in recent years.But relative humidity is bigger during owing to showcase return air; return air is the easy frosting of coil pipe during through colder evaporimeter; for guaranteeing that refrigeration needs often to shut down defrosting, frequent defrosting causes the fluctuation of the interior display of showcase food temperature bigger, has had a strong impact on chilled food quality and shelf life.
Summary of the invention
The purpose of this utility model provides a kind of refrigerator display case that does not need frequent defrosting, with quality and the prolongation shelf life that keeps chilled food in the cabinet.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: the refrigerator display case of this band pre-cooler, comprise cabinet and be arranged on compressor, condenser, throttling arrangement, evaporimeter and refrigeration fan on the cabinet, cabinet is an open front formula structure, front upper at cabinet is provided with air outlet, below the cabinet front portion, be provided with return air inlet, between return air inlet and evaporimeter, also be provided with forecooler; Compressor, condenser, throttling arrangement, evaporimeter and forecooler are connected by pipeline.
Cabinet is provided with air-supply passage, and air outlet and return air inlet lay respectively at the two ends in air channel, and forecooler, evaporimeter and refrigeration fan are positioned at the air channel.
Refrigeration fan is arranged between forecooler and the evaporimeter.
Described air outlet is cellular air outlet, and described return air inlet is a RAG.
Owing between the return air inlet of showcase and evaporimeter, forecooler has been installed, the air that will enter evaporimeter is carried out dehumidification to be handled, solved the excessive problem of air humidity that enters evaporimeter, reduced the frosting degree of evaporator coil, thereby reduced the defrosting number of times, improve the operational efficiency of evaporimeter, further improved the refrigeration performance of showcase by the temperature fluctuation that reduces chilled food.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model refrigeration system operation principle schematic diagram.
The specific embodiment
This refrigerator display case comprises cabinet 9 and is arranged on compressor 1, condenser 2, throttling arrangement 3, evaporimeter 4 and refrigeration fan 8 on the cabinet 9, cabinet 9 is an open front formula structure, front upper at cabinet 9 is provided with air outlet 6, air outlet 6 is cellular air outlets, be provided with return air inlet 7 below cabinet 9 front portions, return air inlet 7 is RAGs.Between return air inlet 7 and evaporimeter 4, also be provided with forecooler 5; Wherein compressor 1, condenser 2, throttling arrangement 3, evaporimeter 4 and forecooler 5 are connected by pipeline, form the work loop of refrigeration system, and its annexation as shown in Figure 2.
Cabinet 9 is provided with air-supply passage, and air outlet 6 and return air inlet 7 lay respectively at the two ends of supply air duct, and forecooler 5, evaporimeter 4 and refrigeration fan 8 are positioned at the air channel, and refrigeration fan 8 is arranged between forecooler 5 and the evaporimeter 4.
Its operation principle is: in refrigeration system, cold-producing medium through behind the evaporimeter again by forecooler, the dehumidification of lowering the temperature is handled to return air.Hot and humid return air reduces by temperature behind the forecooler, and has part steam to condense.After the compressed machine pressurization of refrigerant vapour, become high temperature and high pressure gas, be cooled to cryogenic high pressure liquid, after throttling further reduces temperature through throttling arrangement, reach forecooler by the evaporimeter introducing by condenser.Its air flow is: the forecooler that is provided with behind the showcase return air inlet carries out dehumidification to return air to be handled, and the air after the dehumidification enters supply air duct then through the evaporimeter cooling.
The utility model is by being provided with forecooler, the defrosting number of times reduces, and the temperature rise when having reduced the temperature fluctuation of chilled food in the showcase further and having reduced defrosting has improved the refrigeration performance of showcase, keep original quality of food preferably, prolonged shelf life.
