The application provides a refrigerator, which comprises a refrigerator body and a refrigerating system. Wherein, this refrigerating system includes: a compressor; a condenser; a throttling element; an evaporator; dew removing pipe and control valve.
The refrigerant circulates in each part of the refrigeration system to realize the refrigeration effect. The main circulation process of the refrigerant in each part is as follows: the refrigerant enters a condenser after passing through a compressor; the air enters a throttling element after passing through a condenser; the liquid enters the evaporator after passing through the throttling element; through the evaporator and into the compressor.
Specifically, the compressor compresses a refrigerant gas at a high temperature and a high pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The throttling element expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the throttling element, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can realize the refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled.

In the process that the refrigerant flows from the compressor to the throttling element: one part flows through the condenser, and the other part flows through the dew removing pipe. The control valve is used for adjusting the flow of the refrigerant flowing through the dew removing pipe.
When the refrigerant flows through the dew removing pipe, the dew removing pipe provides heat energy by utilizing system condensation, so that the area where the refrigerant is located is heated, and condensation in the area where the refrigerant is located is prevented. Generally, the larger the refrigerant flow passing through the dew-removing pipe is, the more heat energy is provided by the dew-removing pipe.
In some embodiments, the dew removal tube is disposed on the refrigerator U shell. When the refrigerant flows through the dew removing pipe, the dew removing pipe provides heat energy, so that the U shell of the refrigerator is heated, and condensation of the U shell of the refrigerator is prevented.
In some embodiments, the dew removing tube is provided on a center sill of the refrigerator. When the refrigerant flows through the dew removing pipe, the dew removing pipe provides heat energy, so that the middle beam of the refrigerator is heated, and the dew condensation of the middle beam of the refrigerator is prevented.

It can be understood that, according to the specific application requirements, in some embodiments of the present application, there may be three, four or more dew removing pipes in the refrigeration system, and the dew removing principle is similar to that of two dew removing pipes in the refrigeration system, and therefore, the details are not described herein again.
The principle of dew removal in the case of two dew removal tubes in a refrigeration system is described below.
In some embodiments, the dew point removing pipes in the refrigeration system include a first dew point removing pipe and a second dew point removing pipe, and the control valve is controlled to regulate the flow of the refrigerant flowing through the dew point removing pipes based on the dew point temperature, including:
if the dew point temperature is not higher than the reference temperature, controlling the control valve to close the passage of the refrigerant flowing to the first dew removing pipe;
if the dew point temperature is higher than the reference temperature, the control valve is controlled to open a passage of the refrigerant flowing to the first dew removing pipe.
In this embodiment, a reference temperature (the reference temperature is generally lower than the heating temperature of the second dew removing pipe under any ambient temperature and humidity conditions) is preset for whether to close the passage for the refrigerant to flow to the first dew removing pipe. If the dew point temperature is not higher than the reference temperature, controlling a control valve to close a passage of the refrigerant flowing to the first dew removing pipe, and under the condition, heating the second dew removing pipe to remove dew; and if the dew point temperature is higher than the reference temperature, the control valve is controlled to open a passage of the refrigerant flowing to the first dew removing pipe, and under the condition, the first dew removing pipe and the second dew removing pipe work and heat to remove dew together.
By the method, under the condition that the dew point temperature of the environment of the refrigerator is lower, dew is removed by the operation of the first section of dew removing pipe; under the condition that the dew point temperature of the environment of the refrigerator is higher, the two dew removing pipes work together to remove dew. Therefore, the dew removing effect is ensured, and the energy consumption is reduced.
In some embodiments, a first refrigerant flow rate flowing through the first dew-removing pipe is higher than a second refrigerant flow rate flowing through the second dew-removing pipe.
In this embodiment, when the path of the refrigerant flowing to the first dew-removing pipe is opened, the flow rate of the first refrigerant flowing through the first dew-removing pipe is higher than the flow rate of the second refrigerant flowing through the second dew-removing pipe; that is, in the case where the passage of the refrigerant flowing to the first dew-point removing pipe is opened, the first dew-point removing pipe can supply more heat energy than the second dew-point removing pipe.
By the method, when the dew point temperature is lower, dew is removed by the second dew removing pipe which provides less heat energy; when the dew point temperature is higher, the first dew removing pipe and the second dew removing pipe are used for removing dew together. Therefore, dew removing efficiency is ensured while dew removing effect is ensured.
In some embodiments, a first dew removal tube in the refrigeration system is in parallel communication with the condenser; meanwhile, the inlet of the second dew-removing pipe is communicated with the outlet of the condenser in series.

In some embodiments, the dewing process of the refrigerator in fig. 3 is controlled by:
the method comprises the steps of acquiring the ambient temperature and the ambient humidity of the environment where the refrigerator is located, and determining the dew point temperature T1 of the refrigerator condensation based on the ambient temperature and the ambient humidity.
If T1 is less than or equal to reference temperature T2, control valve 1 closes port A and opens port B, and control valve 2 closes port C and opens port D.

And further, the control valve 1 is controlled according to T1 to adjust the refrigerant flow rate Q1 flowing through the dew removing pipe 1. As T1 increases, Q1 increases. When the total refrigerant flow rate is Q and the refrigerant flow rate flowing through the condenser is Q2, Q is Q1+ Q2, and Q2 is greater than 0.
Through the above description, it can be seen that the refrigerator and the dew removing method provided by the application can meet dew removing requirements under different environments: when the dew point temperature of the environment where the refrigerator is located is low, the dew removing pipe removes dew at a matched low heating temperature; when the dew point temperature of the environment where the refrigerator is located is high, the dew removing pipe removes dew at a matched high heating temperature.
