Description

Refrigerating system of refrigerator

Technical Field

The utility model belongs to the refrigeration plant field, concretely relates to refrigerating system of refrigerator.

Background

Two parts have actually been combined to two interval refrigerators that present house is flourishing: a freezer compartment or freezer compartment (freezer) that maintains a temperature below-18 degrees celsius (i.e., 0 degrees fahrenheit) and freezes food into an ice mass for long-term storage, and a refrigerator compartment or freezer compartment (refrigerator) that maintains a temperature of 3 to 5 degrees celsius (i.e., 31 to 41 degrees fahrenheit) to keep food fresh and fresh at a low temperature.

The refrigerator generally includes a cabinet, a refrigeration system, and an electrical system.

A box body: the case is composed of a structural material and a heat insulating material, and forms a space to store food and prevent heat transfer from the inside and outside. The box body generally comprises an outer box, an inner container and a heat insulating layer. The inner liner of refrigerator is made of ABS or HIPS plate through vacuum forming, and has thickness below 1 mm, white color and smooth surface. Polyurethane foam is widely used as the heat insulating material, so that the heat insulating property is excellent, and the change of the heat conductivity coefficient is small after long-term use.

Some are equipped with a freezing chamber or a refrigerating chamber separately, and some are equipped with both. Some refrigerators now are divided into even four compartments for storing various types of food.

A refrigeration system: the refrigerator basically functions to refrigerate and keep the interior of the refrigerator at a proper low temperature. The refrigerating system generally consists of four basic components, namely a compressor, a condenser, a capillary tube or a thermal expansion valve and an evaporator. The refrigerant is a liquid which can be boiled at low temperature under low pressure, absorbs heat when boiling, the refrigerant continuously circulates in a refrigerating system, a compressor increases the gas pressure of the refrigerant to cause liquefaction conditions, the refrigerant condenses and liquefies to release heat when passing through a condenser, then reduces the pressure and temperature when passing through a capillary tube, and then boils and vaporizes to absorb heat when passing through an evaporator.

Since the early refrigerator mostly used R-12 refrigerant (i.e. difluoro-dichloromethane), and ozone layer of atmosphere is destroyed, refrigerant such as R600a/R134a/R404 is often used nowadays.

In addition, dry filters are typically installed at the capillary inlet end because of the inevitable presence of some moisture and impurities in the system.

An electrical system: the refrigerator uses electricity as main energy source, and uses motor to drive compressor or refrigeration diode, and is generally equipped with relay protector and temp. controller.

The refrigerator motor using the compressor is classified into a resistance split-phase starting type, a capacitance starting type and a capacitance starting and capacitance running type according to different starting methods. The motor of the totally-enclosed compressor is arranged in the refrigerating system, is contacted with refrigerant and refrigerating machine oil for a long time, and bears pressure, high temperature and the like, so the totally-enclosed compressor has the requirements of refrigerant and refrigerating machine oil resistance, stable electrical performance, high temperature resistance, vibration and impact resistance, larger starting torque, cleanness and no water and the like.

With the improvement of the living taste of people, the requirements of red wine collection and quality identification appear, and the introduction is introduced by a master Yang Weiyun (Viviane) of vineyard management of the first order of China: "the most critical factor affecting the taste of wine is temperature. The temperatures here include: 1. the storage temperature is that the wine is 'fresh and alive living' liquid, is easily influenced by the environment, the wine which is not opened can be drunk in a short period of time and can be stored in a shady and cool dark place (the air-conditioned room is avoided, the temperature fluctuation is large because the wine is opened and closed in time), but if the wine is rare wine, the wine needs to be stored for years, the value is high, a constant-temperature wine cabinet needs to be purchased, and the temperature of the wine cabinet is adjusted to 12-15 ℃ as far as possible, so that the wine cabinet is the ideal temperature for storing the wine for a long time. But the automobile trunk, the kitchen, the balcony and the light are not suitable for storing the wine.

2. The drinking temperature is not right, the good wine is not good, the wine has many types, and the drinking temperature of different types of wine is also different. "

Therefore, the constant-temperature wine cabinet is best for preserving the wine, but the indoor space of a common family is limited, the constant-temperature wine cabinet occupies a field, and the constant-temperature wine cabinet is easy to idle when no wine exists, so that the market needs a refrigerator which is more convenient and more suitable for preserving the wine.
