The specific embodiment
Referring to Fig. 1, the utility model cooling and warming conversion hysteria refrigerator, it is provided with insulation casing 11, the steam compression type circulatory system is mainly by compressor 1, four-way change-over valve 2, case outer heat-exchanger 3, capillary 6,8,9, heat exchanger 4, fluid reservoir 10 and working media are formed in the device for drying and filtering 5, case; Four paths of four-way change-over valve 2 connect compressor exhaust pipe, air intake duct respectively, heat exchanger in case outer heat-exchanger and the case; Electrical apparatus control system is provided with switch block and the communication direction of 2 four paths of related circuit control four-way change-over valve and the operation of other parts.Below in conjunction with relevant accompanying drawing, relevant technologies of the present utility model aspect is described in detail:
Referring to Fig. 2, when it is in refrigerating state, compressor 1 absorbs the refrigerant gas of normal pressure and temperature from fluid reservoir 10, compressed process cold-producing medium becomes the gas of HTHP, flow to the outer hot device 3 of heat exchange of case by four-way change-over valve 2, cold-producing medium in low temperature environment, emit heat betwixt and self be condensed become in the temperature liquid, the back is at capillary 8,6, under 9 the throttling action, pressure reduces, temperature reduces, and enters in the case heat exchanger 4 vaporization of absorbing heat, reduction the temperature inside the box, the cold-producing medium that the is vaporized fluid reservoir 10 that four-way change-over valve 2 entered the gas-liquid separation effect of flowing through suffers liquid hammer to prevent compressor, after enter compressor 1 again and carry out compression process.Move in circles.The bypass (permission of the check valve shown in the figure flows to from right to left) that cold-producing medium is not flowed through and is provided with check valve 7 to the restriction of flowing because of the folk prescription of check valve in this system's flow graph.5 of devices for drying and filtering absorb moisture, the effect of impurity and dust in the filtration cycle system, the long-term operation performance of safeguards system simultaneously.This system's raising middle flask outer heat-exchanger 3 is as condenser, and heat exchanger 4 is as evaporimeter in the case.
Referring to Fig. 3, when it is in when heating state, compressor 1 absorbs the refrigerant gas of normal pressure and temperature from fluid reservoir 10, compressed process cold-producing medium becomes the gas of HTHP, flow to the hot device 4 of heat exchange in the case by four-way change-over valve 2, cold-producing medium in case, emit heat in the environment betwixt and self be condensed become in the temperature liquid, the back is at capillary 9, under 8 the throttling action, pressure reduces, temperature reduces, enter the heat that case outer heat-exchanger 3 carries out in the absorbing environmental and vaporize, the cold-producing medium that the is vaporized fluid reservoir 10 that four-way change-over valve 2 entered the gas-liquid separation effect of flowing through suffers liquid hammer to prevent compressor, after enter compressor 1 again and carry out compression process.Move in circles.Cold-producing medium is when the bypass in parallel of flow through check valve 7 and capillary 6 in this system's flow graph, because of the metering function of capillary 6 is by being provided with the bypass of check valve 7.5 of devices for drying and filtering absorb moisture, the effect of impurity and dust in the filtration cycle system, the performance of the long-time running of safeguards system simultaneously.This system's raising middle flask outer heat-exchanger 3 is as evaporimeter, and heat exchanger 4 is as condenser in the case.From the angle analysis of energy, the efficiency usage factor of this moment (ratio of input energy and output energy) is big by 1 during than kind of refrigeration cycle.
What be worth particularly pointing out is: the parts that play throttling action during kind of refrigeration cycle are capillary 8,6,9 three parts, and the parts that play throttling action in heating circulation are capillary 9,8.Comparatively speaking, during kind of refrigeration cycle throttling action big with heat circulation time.She Ji reason is evaporating temperature (and pressure) evaporating temperature when being lower than kind of refrigeration cycle (and pressure) of system in the time of will causing kind of refrigeration cycle like this, the temperature inside the box of requirement when guaranteeing actual use.If the phase cross-demand is arranged, the evaporating temperature of system when promptly requiring kind of refrigeration cycle (and pressure) is higher than the evaporating temperature (and pressure) that heats circulation time, and the closure that also can oppositely adjust check valve 7 gets final product.The also available magnetic valve of check valve 7 replaces, and difference need on the circuit diagram to be to carry out different control (energising or not) according to circulation is different.
Referring to Fig. 4, its electric control principle is as follows:
(1) main circuit is gone in heating temperature control system device 12 and 13 series connections of refrigeration temperature control device, in order to the temperature in the sensation case, and controls compressor electric motor 14, fan electromotor 15, realizes the control to the temperature inside the box.Turn-on temperature as heating temperature control device 12 is 45 ℃, and shutdown temperature is 60 ℃; The turn-on temperature of refrigeration temperature control device 13 is-12 ℃, and shutdown temperature is-24 ℃.When whole system is freezed, because of the temperature inside the box certainly below the turn-on temperature of heating temperature control device, so the heating temperature control device is always logical, promptly the heating temperature control device is equivalent to lead, does not work only start-stop operation under the control of refrigeration temperature control device of cross box.When whole system heats, because of the temperature inside the box does not work, only start-stop operation under the control of heating temperature control device of cross box.The effect of fan is a heat exchange efficiency of strengthening case outer heat-exchanger 3, so and compressor parallel, realize and the Compressor Synchronous start-stop.
(2) conversion and control of the present utility model can realize with a simple single-pole double-throw switch (SPDT) 16.When switch connection I number end, whole system will be carried out according to the refrigeration control mode, and the indicator lamp 17 that freezes this moment is bright.When switch connection II number end, whole system will be carried out according to heating control mode, and this moment, burner on light 18 was bright.
Electric heater 19 (as Fig. 4 institute city) also can be set in the above-mentioned incubator.Electric heater is set carries out complementary electrical heating, in order to improve heating-up temperature.
Heat exchanger 4 can be the mode of two or more different heat exchanger in series in the case of the present utility model, adjusts coupling by the area of dissipation to each heat exchanger, can realize having the product of two or more different warm areas.As: during kind of refrigeration cycle, two chambers are respectively refrigerated storage temperature (0 ℃～10 ℃) and refrigerating chamber (below 18 ℃); Heat circulation time, two chambers are respectively little heating-up temperature (15 ℃～25 ℃) and hot drink chamber (45 ℃～60 ℃).
