Abstract
The present invention relates to a condenser pressure maintaining energy-saving type refrigeration system for a refrigerator. A refrigerant circulation system is composed of a compressor, a condenser, a filter, a capillary pipe and an evaporator. The present invention is characterized in that a flow regulation mechanism is arranged on a pipeline which is led to the capillary pipe from the condenser. The start and the stop of the flow regulation mechanism are synchronous with the start and the stop of the compressor. A high pressure refrigerant in the condenser can not enter the evaporator through the capillary pipe after the compressor is stopped by the arrangement of the flow regulation mechanism, or only a small part of the high pressure refrigerant can continuously flow towards the evaporator to maintain the potential energy of the high pressure refrigerant in the condenser. The loss during the start and the stop of a refrigerator is effectively reduced by the present invention. The present invention has the advantages of simple structure and reliable functions.
Description
Technical field:
The present invention relates to refrigerator refrigeration system.A kind of refrigerator refrigeration system that constitutes refrigerant-cycle systems by compressor, condenser, filter, capillary and evaporimeter of more specifically saying so.
Background technology:
At present widespread usage constitutes the refrigerator of refrigerant-cycle systems by compressor, condenser, filter, capillary and evaporimeter, its working method is: when temperature in the casing is higher than setting value, compressor start, cold-producing medium is pressed towards condenser, condenser pressure rising, evaporator pressure are reduced, cold-producing medium outwards dispels the heat in condenser and changes liquid phase into by gas phase, behind capillary-compensated, enter evaporimeter, heat in the absorption casing changes gas again into and is inhaled into compressor, and so circulation realizes freezing; When temperature in the casing was lower than setting value, compressor promptly quit work.But in the practical work process, after compressor shutdown, the high-pressure refrigerant in the condenser continues through capillary flow to evaporimeter; along with pressure reduction between condenser and the evaporimeter reduces; the refrigerant temperature that enters evaporimeter raises, thereby loses refrigeration gradually, even can heating fumigators.And when compressor starts once more, need certain hour to rebulid pressure reduction and just can enter normal kind of refrigeration cycle.As seen, this mode exists the energy loss after compressor start and the shutdown inevitably, i.e. startup-shutdown loss.
Summary of the invention:
Technical problem to be solved by this invention is to avoid existing weak point in the above-mentioned prior art, provides a kind of condenser pressurize energy-saving refrigerator refrigeration system.Reach energy-conservation purpose by the energy loss that reduces startup-shutdown.
The technical scheme that technical solution problem of the present invention is adopted is:
The present invention constitutes refrigerant-cycle systems by compressor, condenser, filter, capillary and evaporimeter,
Design feature of the present invention is to lead on the pipeline capillaceous at described condenser, and flow control device is set, and described flow control device is synchronously opened along with the unlatching of compressor, synchronously closes along with the shutdown of compressor; Compressor release branch road is set, described release branch road is to be communicated with the low-pressure side at evaporimeter place by the exhaust outlet of release capillary with compressor, is serially connected with the check valve or the magnetic valve that stop the anti-stream of condenser mesohigh cold-producing medium in the pipeline between compressor and condenser.
Concrete working method of the present invention is that flow control device is opened when compressor is started shooting, and refrigerant circulation passage is unblocked, realizes normal kind of refrigeration cycle; Control flow control device in the time of compressor shutdown; hinder flowing of cold-producing medium with it; make the high-pressure refrigerant in the condenser after compressor shutdown, can not enter evaporimeter by capillary; or only there is the small part cold-producing medium can continue to flow to evaporimeter; with the potential energy that keeps condenser mesohigh cold-producing medium to be had, thereby reduced shutdown loss effectively.When compressor started once more, flow control device was opened simultaneously, and system reaches stable state very soon, had equally also reduced the start loss.Compared with the prior art, the present invention effectively reduces the energy consumption of refrigerator.Its refrigerant system configurations is simple, reliable in function.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a specific embodiment of the invention structural representation.
The specific embodiment:
Referring to Fig. 1; present embodiment constitutes refrigerant-cycle systems by compressor 1, condenser 2, filter 3, capillary 4 and evaporimeter 5; lead at condenser 2 on the pipeline of capillary 4; flow control device 6 is set; this flow control device 6 is opened and is synchronously opened along with compressor 1; synchronously close along with the shutdown of compressor 1, be used under compressor 1 stopped status, hinder cold-producing medium the flowing in the high-pressure side condenser 2 to the low-pressure side at evaporimeter 5 places.Flow control device 6 can be a magnetic valve etc.
In that condenser 2 is implemented can normally start in order to guarantee compressor 1 under the situation of pressurize, can the release branch road be set at compressor 1, so that exhaust outlet of compressor and air entry are carried out pressure balance.Concrete mode as shown in Figure 2, adopt release capillary 7 that the exhaust outlet of compressor 1 is communicated with the low-pressure side at evaporimeter 5 places, and in the pipeline between compressor 1 and the condenser 2, be connected in series check valve or magnetic valve 8, be used for stoping anti-stream of high-pressure refrigerant of condenser 2.
Fig. 2 illustrates; for fear of under compressor 1 opening,, can in the release branch road, connect pressure-relief valve 9 is set owing to the shunting of release capillary 7 influences refrigeration; pressure-relief valve 9 synchronously cuts out along with the unlatching of compressor 1, synchronously opens along with the shutdown of compressor 1.
Operation principle:
Under compressor 1 open state, flow control device 6 is opened, and pressure-relief valve 9 cuts out, and cold-producing medium maintains under the normal kind of refrigeration cycle state.
In case compressor 1 is shut down, flow control device 6 is closed immediately, and the cold-producing medium that hinders in the condenser 2 continues to flow, or allows the small part cold-producing medium to continue to flow, and reduces shutdown loss.Simultaneously, condenser 2 mesohigh states are kept, and reducing the start loss when restarting for compressor 1 provides necessary guarantee.After compressor 1 was shut down, the release branch road was devoted oneself to work, and compressor 1 high-pressure exhaust makes exhaust outlet of compressor and air entry pressure be able to balance by the low-pressure side release of release capillary 7 to evaporimeter 5 places, guaranteed the reliability that compressor starts again.
After compressor 1 restarted, the release branch road was turned off, because condenser 2 keeps high pressure, system reaches stable state very soon, had reduced the start loss equally effectively.
