Abstract
The utility model discloses an intelligent leeway type defrosting device for a cold storage. A leeway switch, a signal wire and a controller are additionally mounted on a conventional defrosting system of the cold storage; the frosting state is automatically judged by testing the wind pressure of a fin type heat exchanger; the parameter of a wind pressure value can be set according to the pipe row number, the frosting state and the fin space of heat exchangers of different air coolers. After the air cooler is started for refrigerating, the cold storage starts cooling, wind passes through the fin type heat exchanger and forms the pressure at pipe mouths L and H of the leeway switch; at the same time, the leeway switch is turned on and does not transmit a defrosting signal to the controller; when the fin type heat exchanger is frosted to a certain degree, air volume passing through the fine type heat exchanger is gradually reduced; when the air volume is low to a set value of the leeway switch, contacts of the leeway switch are switched off and the leeway switch outputs the defrosting signal to the controller; meanwhile, after the controller detects that the temperature of a refrigerant muffler pipe reaches a defrosting set value, the fin type heat exchanger automatically enters the defrosting state; when the temperature of the fin type heat exchanger reaches a defrosting exit set value, the defrosting is stopped and a defrosting period is finished.
Description
Technical field
The utility model relates to a kind of freezer defrosting device, and especially leeway formula intelligence freezer defrosting device, belongs to changes in temperature mechanical equipment technical field.
Background technology
The Cold Chain Logistics market of China is being faced with fast-developing historic opportunities and challenge.At present, the commercial freezer area of China has more than 700 ten thousand square metres, approximately 30,000 of thermal cars, and 6900 of refrigerated railway cars, also can not meet growing demand far away.In coming 10 years, the refrigerator car of China will increase more than 28% every year, and freezer increases more than 30% every year.Along with the development of China's economic, from cold drink, meat products, vegetable and fruit to fresh flower, medicine, electronic product, make many people still feel strange " cold chain transportation " and be penetrated into different social sectors, therefore freezer demand grows with each passing day, but the energy-conserving and environment-protective of freezer are still troubling, and especially quality is uneven.Wherein the defrost energy consumption of freezer is especially unreasonable, at present freezer defrost in service be substantially temperature with timing in conjunction with defrost, once defrost periods setting-up time has arrived, with regard to defrost, temperature is raised to exit design temperature or defrost time is up and just exits, and causes the defrost time longer, and power consumption is larger.Some state there will be the situation that does not have white defrost, causes energy consumption waste.
Summary of the invention
In order to solve that current freezer defrost time is long, power consumption is large and the problem such as weak effect, the present utility model a kind of leeway formula intelligence freezer defrosting device, leeway switch, holding wire and controller have been increased at former refrigeration storage system, air quantity by test finned heat exchanger carrys out automatic decision frosting state, automatically control combination and the disconnection of leeway switch, offer controller by holding wire, realize intelligent defrost operation.Can greatly shorten the defrost time like this, reduce defrost power consumption, there is the effect of energy-saving and emission-reduction and low-carbon environment-friendly.
technical scheme
The technical scheme in the invention for solving the technical problem is: a kind of leeway formula intelligence freezer defrosting device, in the middle of the left side of rectangle air-cooler, connect leeway switch, holding wire and controller on leeway switch, are connected, two circular blower fans before air-cooler, are connected, connect connecting terminal block and defrost heater strip on the left side of air-cooler, connected cold-producing medium feed tube, cold-producing medium muffler and finned heat exchanger in the upper right side of air-cooler.Before finned heat exchanger, connected leeway switch, leeway switch has connected controller by holding wire.
beneficial effect
The beneficial effects of the utility model are: the method and device can be widely used on freezer equipment, substitute the existing defrosting method of timing or constant temperature, this device can reach white defrost, the frostless Based Intelligent Control effect of not changing, thereby solve the power wastage that existing freezer timing defrost causes, the unreasonable problem that temperature fluctuation in storehouse is large, thereby realized energy-saving and intellectuality that freezer moves.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Accompanying drawing 1 is the main TV structure schematic diagram of example of leeway formula intelligence freezer defrosting device.
Accompanying drawing 2 is the example plan structure schematic diagram of leeway formula intelligence freezer defrosting device.
Accompanying drawing 3 is the example side-looking structural representation of leeway formula intelligence freezer defrosting device.
In figure, 1, air-cooler; 2, leeway switch; 3, holding wire; 4, controller; 5, blower fan; 6, connecting terminal block; 7, defrost heater strip; 8, cold-producing medium feed tube; 9, cold-producing medium muffler; 10, finned heat exchanger.
Detailed description of the invention
In accompanying drawing 1,2,3: 1, air-cooler; 2, leeway switch; 3, holding wire; 4, controller; 5, blower fan; 6, connecting terminal block; 7, defrost heater strip; 8, cold-producing medium feed tube; 9, cold-producing medium muffler; 10, finned heat exchanger.It is characterized in that: a kind of leeway formula intelligence freezer defrosting device, on conventional freezer defrosting system, install leeway switch, holding wire and controller additional, air quantity by test finned heat exchanger carrys out automatic decision frosting state, and airflow value can be carried out setup parameter according to different air-cooler Tube Sheet of Heat Exchanger rows, frosting state and spacing of fin.
When air-cooler starts after refrigeration, freezer starts cooling, wind from finned heat exchanger by and at the L of leeway switch, H mouth of pipe mineralization pressure, open and control now leeway switch opens, do not transmit defrost signal to controller, when finned heat exchanger frosting to a certain extent, air quantity by finned heat exchanger just reduces gradually, when low to leeway switch when setting value, leeway switch contact disconnects, to controller output defrost signal, detect cold-producing medium muffler temperature with Time Controller and also reached defrost setting value, enter defrost state, when reaching defrost, finned heat exchanger temperature exits when setting value, defrost stops, complete a defrost periods.
