Abstract
The utility model discloses a dual-temperature control vehicle-mounted refrigerator refrigeration system with random control and good effect from refrigeration to cold storage. The system comprises at least one compressor refrigeration system and two evaporator systems, wherein the compressor refrigeration system is controlled by two relays; each relay is controlled by an electromagnetic valve, and the electromagnetic valve is controlled by a temperature sensor; and a cold source of a refrigerated chamber is provided by cold sources of the respective evaporators, and the electromagnetic valve respectively controls one evaporator system. The dual-temperature control vehicle-mounted refrigerator refrigeration system has precision control with the effect of electromagnetic valve so that each refrigerated chamber can realize the function of random temperature control from cold storage to refrigeration.
Description
Technical field
The utility model relates to a kind of two temperature control car refrigerator refrigeration system, the especially a kind of car refrigerator two temperature control system that can freely control temperature
Technical background
General single compressor refrigeration system; it is the startup-shutdown of controlling compressor by a temperature controller; to reach the requirement of control temperature; the refrigerator that has has two cool rooms; way commonly used is to stay certain space between refrigerating chamber and refrigerating chamber; reduce the temperature of refrigerating chamber by the natural convection air between refrigerating chamber and the refrigerating chamber; gap one between refrigerating chamber and refrigerating chamber regularly; environment temperature is low more; the temperature of refrigerating chamber is low more; environment temperature is high more, and the temperature of refrigerating chamber is just high more.But because car refrigerator is in outdoor application, sometimes outdoor temperature is up to 45 degree, sometimes temperature but has only about 10 degree, and under the bigger situation of this variations in temperature, the temperature of refrigerating chamber just can't realize accurate control by the cross-ventilation by self.
People brought into use fan to control the temperature of refrigerating chamber afterwards, made the temperature controlled more even of refrigerating chamber and refrigerating chamber.In this case, there is a chamber can only do cold cabin all the time, and is that refrigerating chamber and refrigerating chamber are fixed.
But growth in the living standard along with people, people are also more and more higher to the requirement of refrigeration product, need possible today whole refrigerator to be in freezing state, also may need whole refrigerator to be in frozen state, perhaps select a chamber to do refrigeration at any time, another be do freezing.Reach above function,, the heat exchange pattern of above nature or air strong convection mode just do not realize
The utility model content
According to above situation, it is a kind of from the freezing two temperature control car refrigerator refrigeration system of freely controlling to refrigerated storage temperature that the utility model provides.。
It is made up of at least one compressor refrigeration system, dual-evaporator system, a temperature control system, and described temperature control system comprises the independent control system of each cooling room.The cooling room temperature controller is directly controlled the magnetic valve that is installed in the evaporimeter refrigeration system, on-off by magnetic valve is controlled corresponding relays, when the temperature of certain cooling room reaches when temperature is set, the signal of the temperature sensor feedback of this cool room disconnects magnetic valve, cold-producing medium by the evaporimeter refrigerating circuit of this solenoid control stops circulation, this cool room stops refrigeration, relay by this solenoid control disconnects simultaneously, when two cool rooms all reach the temperature of setting, two relays being controlled respectively by two magnetic valves all disconnect, and compressor quits work.This moment two cooling rooms temperature recovery, when certain cooling room took the start condition that temperature controller sets to, magnetic valve began work, relay is connected, compressor starts work, whole system begins new circulation.
Description of drawings
Accompanying drawing is the structural representation of a kind of two temperature control of the utility model car refrigerator refrigeration system.
1. temperature controller A, 2. temperature controller B, 3. compressor refrigeration system, 4. relay A, 5. relay B, 6. magnetic valve A, 7. magnetic valve B, 8. evaporimeter refrigeration system A, 9. evaporimeter refrigeration system condenser B.10.
The specific embodiment
By accompanying drawing as can be known, the two temperature of present embodiment control car refrigerator refrigeration system is mainly by a cooling room, compressor assembly 1 and the double evaporators refrigeration system (8 that is complementary with it, 9), temperature control system (1,2) form, described cooling room is the casing of two chambers, directly controls refrigeration by compressor refrigeration system 3.During energising, because the temperature of two chambers all is lower than temperature is set, the magnetic valve of two chambers all is in opening state, and the cold-producing medium that sends by compressor assembly makes two evaporimeter refrigeration systems begin circulation, and whole cooling room begins refrigeration, when the temperature of a chamber reaches when temperature is set, the temperature sensor of this chamber is given magnetic valve with signal feedback, and magnetic valve disconnects, and cold-producing medium stops circulation in this chamber, this chamber stops refrigeration, and the relay by this chamber battery valve control disconnects simultaneously.When two cooling rooms all reach when temperature is set, the relay of two solenoid control correspondingly all disconnects, this moment, compressor quit work, and whole refrigerator is in halted state, the temperature bottom out of two cooling rooms, when being raised to, the temperature of certain chamber temperature is set when above, temperature sensor is passed to magnetic valve with signal, the magnetic valve path, and the while is by the relay path of this solenoid control, compressor starts work, whole refrigeration system begins new kind of refrigeration cycle.
