Abstract
The invention provides a refrigerator defrosting system which comprises a compressor, a condenser and an evaporator, wherein a defrosting pipeline is arranged between the compressor and the condenser; the main part of the defrosting pipeline is arranged at the position of the evaporator, so that a high temperature and high pressure refrigerating agent can be drained onto the surface of the evaporator; a switching valve is arranged on the defrosting pipeline between the compressor and the evaporator; and the switching valve is controlled by the refrigerator defrosting system through electric control signals to be switched on or switched off. A refrigerator defrosting method comprises the following steps: S1: setting electric control signals of the refrigerator defrosting system for switching on and switching off the switching valve; S2: when the system detects that the defrosting process is needed, outputting an electric control signal by the system to enable the switching valve to be in a switching-off state; and S3: when the system detects that the defrosting process is not needed, outputting an electric control signal by the system to enable the switching valve to be in a switching-on state. By using the heat of a high temperature and high pressure condensing agent for defrosting, the invention can lower the temperature outside the refrigerator body and reduce the heat dissipated to the environment, thereby protecting the environment.
Description
Technical field
The present invention relates to refrigerator defrost refrigeration control technology field, relate in particular to the technology that the used heat that utilizes refrigerator carries out defrost.
Background technology
Current refrigerator generally all adopts the heating of heater strip to carry out defrost and handles, and the heat of the high-temperature high-pressure refrigerant that comes out from compressor is taken as the environment of used heat around being dispersed in.The structured flowchart of current refrigerator refrigeration system as shown in Figure 1, the cold-producing medium of HTHP comes out from compressor, directly entering condenser cools off, the evaporimeter of flowing through then freezes, the entrained heat of high-temperature high-pressure refrigerant that comes out from compressor has just slatterned like this, and in the time of the needs defrost, also need to provide in addition heat energy to carry out defrost, waste energy.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of refrigerator defrosting system and method.
The invention provides a kind of refrigerator defrosting system, comprise compressor, condenser, evaporimeter, compressor, condenser, pipeline is set between the evaporimeter makes high-temperature high-pressure refrigerant come out from compressor, directly entering condenser cools off, the evaporimeter of flowing through then freezes, between described compressor and the described condenser defrost pipeline is set, the main part of described defrost pipeline is arranged on described evaporimeter place, described high-temperature high-pressure refrigerant is drained into the surface of evaporimeter, defrost pipeline between described compressor and the described evaporimeter is provided with switch valve, and described switch valve passes through the electric control signal gauge tap by the refrigerator defrosting system.
As a further improvement on the present invention, described switch valve is a triple valve, and three interfaces of described triple valve connect the pipeline of described compressor, condenser, evaporimeter respectively.
As a further improvement on the present invention, also comprise check valve, described check valve is arranged on the described defrost pipeline.
A kind of refrigerator defrosting method may further comprise the steps:
S1: set the closed and disconnected electric control signal of refrigerator defrosting system to switch valve;
S2: when system detects when needing defrost, make switch valve be in off-state, make the surface of refrigerant flow direction evaporimeter of HTHP and defrost, and then flow back to condenser by system's output electric control signal;
S3: when system detects when not needing defrost, make switch valve be in closure state by system's output electric control signal, in the case, the refrigerant flow direction condenser.
The invention has the beneficial effects as follows: the heat of the HTHP condensing agent that system and method utilization of the present invention is come out from compressor comes defrost, and be to realize by the pipeline flow-direction that changes condensing agent, utilize used heat to carry out defrost, do not need to increase in addition thermal source, energy savings.Utilize the heat of HTHP condensing agent to come defrost, can lower the outer temperature of refrigerator body, reduce the heat that is disseminated in the environment, protected environment.
System and method of the present invention will drain into evaporimeter by a triple valve from the high-temperature high-pressure refrigerant that compressor comes out, and then draw by a unidirectional raft and to get back to the condenser place; When system detects when needing defrost, make triple valve beat the direction of dotted arrow indication in figure (defrost pipeline) by system's output electric control signal, make the surface of refrigerant flow direction evaporimeter of HTHP and defrost, and then flow back to condenser, when not needing defrost, make triple valve beat the direction of solid arrow indication in figure by system's output electric control signal, in the case, the flow direction of cold-producing medium is the same with the current refrigerator refrigeration system, and the effect of check valve is to guarantee to be unlikely to make the refrigerant flow direction evaporator surface in the case and influence refrigeration among the figure.Rationally simple stringing is convenient in the utilization of triple valve.
