Abstract
The invention discloses a direct-cooling mechanically-controlled refrigerator for a wide climate zone. The direct-cooling mechanically-controlled refrigerator comprises a closed loop formed by sequentially connecting a compressor, a condenser, a capillary pipe and an evaporator to a refrigerant pipeline, wherein a condensation pipeline passes through a first refrigeration evaporator at first, then passes through a freezing evaporator, and finally passes through a second refrigeration evaporator; and a throttle is arranged on a pipeline between the first refrigeration evaporator and the freezing evaporator. According to the invention, a double-throttling technology is adopted, secondary throttling is carried out after the refrigerant enters a refrigeration chamber, so that an evaporation temperature of the refrigerant entering a freezing chamber is lowered, and then performance and energy efficiency requirements of products can be met, and the cost of the products is reduced.
Description
Technical field:
The present invention relates to a kind of refrigerator temp. compensation equipment, be specially a kind of direct-cooled machine control refrigerator for wide climate zone.
Background technology:
Refrigerator widely uses now; refrigerator can be divided into Four types according to climate type; but the minimum environment temperature being applicable to refrigerator standard is 10 degree; but in Rural Areas of China; the environment temperature that refrigerator uses has portion of time below this temperature; direct-cooled machine control refrigerator is due to the restriction of self; when environment temperature is lower; refrigerant storage can be more in condenser; cause that to enter refrigeration evaporator cold-producing medium less; make compressor operating time elongated or do not shut down for a long time, thus temperature of refrigerating chamber zero passage, affect the normal use of refrigerator.For head it off, adopt refrigerant flow direction, advanced refrigerating chamber, then refrigerating chamber, refrigerating chamber mode.But this result, because refrigerating chamber thermic load is comparatively large, the evaporating temperature entering refrigerating chamber is relatively high, for ensureing properties of product and efficiency, having to use compressor that is efficient and high refrigerating capacity to make up, thus making the holistic cost of product increase.
Summary of the invention:
In order to solve the problem existing for background technology, the invention provides a kind of easy control program newly, specific as follows:
A kind of direct-cooled machine control refrigerator for wide climate zone, comprise by compressor, condenser, capillary, evaporimeter is connected to a closed-loop path of the up one-tenth of condensing agent pipeline in turn, described evaporimeter comprises the refrigeration evaporator being located at refrigerating chamber and the refrigerating evaporator being located at refrigerating chamber, described refrigeration evaporator has two, be respectively the first refrigeration evaporator and the second refrigeration evaporator, condensation pipe is first by the first refrigeration evaporator, pass through refrigerating evaporator again, eventually pass the second refrigeration evaporator, pipeline between first refrigeration evaporator and refrigerating evaporator is provided with flow controller.
Further, described condenser and intercapillary pipeline are also provided with device for drying and filtering.
Cold-producing medium flows through device for drying and filtering by compressor through condenser, after capillary-compensated, is introduced into the first refrigeration evaporator, then after the step-down of flow controller second throttle, enters refrigerating evaporator and the second refrigeration evaporator completes circulation.
The present invention adopts double throttle technology, and cold-producing medium is introduced into the first refrigerating chamber, then carries out second time throttling, the evaporating temperature entering refrigerating chamber is reduced, thus can meet performance and the efficiency requirement of product, and reduce the cost of product.
Accompanying drawing illustrates:
Fig. 1 is each member connection structure schematic diagram of the present invention.
Detailed description of the invention:
See accompanying drawing, a kind of direct-cooled machine control refrigerator for wide climate zone, comprise by compressor 1, condenser 2, capillary 6, evaporimeter is connected to a closed-loop path of the up one-tenth of condensing agent pipeline in turn, described evaporimeter comprises the refrigeration evaporator being located at refrigerating chamber and the refrigerating evaporator 4 being located at refrigerating chamber, described refrigeration evaporator has two, be respectively the first refrigeration evaporator 3 and the second refrigeration evaporator 8, condensation pipe is first by the first refrigeration evaporator 3, again by refrigerating evaporator 4, eventually pass the second refrigeration evaporator 8, pipeline between first refrigeration evaporator 3 and refrigerating evaporator 4 is provided with flow controller 5.
Further, the pipeline between described condenser 2 and capillary 6 is also provided with device for drying and filtering 7.
