The utility model discloses need not add extra firing equipment, not need frequent start or frequency conversion energy adjustment yet, can guarantee still can guarantee higher temperature -controlled precision on a large scale under the condition that the heating load changes, have simple structure, easy realization, temperature -controlled precision height and the high advantage of operational reliability.
Description
Technical field
The utility model relates to refrigerating field, specifically a kind of refrigeration system energy conditioner.
Background technology
Refrigeration Technique is applied to social every field, and some occasions high to refrigeration required precision need refrigerating plant to provide comparatively stationary temperature to use side, to ensure the normal work using side apparatus or device, and the thermic load of side apparatus or device in reality, in a lot of situation, is used to be often real-time change as required.Ensure that the use side of refrigerating plant is steady temperature mainly through following measures at present:
One is that refrigerating plant does not carry out energy adjustment, and carrys out balanced system device for cooling and exceed the part refrigerating capacity using side thermic load using side to install firing equipment additional, and its refrigeration and heating are the independent devices of two covers, can ensure the temperature temperature-controlled precision using side; But it is not extra firing equipment adds the complexity of equipment itself, and running cost is high, energy-conservation.
Two is according to factors such as the height using side temperature, controls the opening of refrigerating plant, stops reaching and use side temperature to change within the scope of one.Though this control mode is simply easy to realize, because start/stop of compressor needs the time interval of 3 minutes, its temperature control precision is relatively poor, and high frequent start and stop can reduce its service life.
Three is the refrigerating capacitys according to using the change of side thermic load to regulate compressor, ensures to use side steady temperature as used the compressor of Frequency Converter Control.But because frequency conversion is considering that the special occasions of Electro Magnetic Compatibility can not use, and the initial stage of use frequency converter drops into and later maintenance cost is higher.
Utility model content
The purpose of this utility model is to provide the energy adjustment refrigerating plant that a kind of structure is simple, temperature-controlled precision is high, still can ensure high temperature-controlled precision in thermic load wide variation situation.
The technical solution of the utility model is as follows:
A kind of refrigeration system energy conditioner, include the refrigeration system be in turn connected into by pipeline by compressor, temperature sensor, condenser, first throttle device, evaporimeter and pressure sensor, it is characterized in that: be connected with by the bypass circulation that magnetic valve and capacity adjusting valve can be adjusted to form between the suction of described compressor, exhaust outlet, between the outlet of described condenser and the air entry of described compressor, be connected with the hydrojet loop be made up of hydrojet magnetic valve and the second throttling arrangement.
Described refrigeration system energy conditioner, is characterized in that: described temperature sensor is positioned at described exhaust outlet of compressor side.
Described refrigeration system energy conditioner, is characterized in that: described pressure sensor is positioned at described compressor air suction mouth side.
In the utility model, evaporation side load diminishes, cold-producing medium evaporation not exclusively, pressure of inspiration(Pi) can reduce, when pressure sensor records suction pressure of compressor lower than a certain setting value, magnetic valve can be adjusted to open, from exhaust outlet of compressor gaseous refrigerant out through magnetic valve and capacity adjusting valve can be adjusted, finally get back to compressor, reduce because exhaust bypass causes compressor to export energy, but along with evaporation side load reduces further, capacity adjusting valve bypass amount increases, suction side temperature can increase, when the temperature that temperature sensor records exhaust outlet of compressor side is higher than design temperature certain value, hydrojet magnetic valve is opened, after condenser, liquid refrigerant is through hydrojet magnetic valve and the second throttling arrangement, finally get back to compressor air suction mouth, suction temperature reduces, compressor normal operating condition can be ensured.
The beneficial effects of the utility model:
The utility model does not need to add extra firing equipment, frequent start or frequency conversion energy adjustment is not needed yet, can ensure still can ensure higher temperature-controlled precision when thermic load wide variation, have structure simple, be easy to the advantage that realizes, temperature-controlled precision is high and functional reliability is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of refrigeration system energy conditioner, include the refrigeration system be in turn connected into by pipeline by compressor 1, temperature sensor 2, condenser 3, first throttle device 5, evaporimeter 7 and pressure sensor 8, be connected with by the bypass circulation that magnetic valve 9 and capacity adjusting valve 10 can be adjusted to form between the suction of compressor 1, exhaust outlet, between the outlet of condenser 3 and the air entry of compressor 1, be connected with the hydrojet loop be made up of hydrojet magnetic valve 4 and the second throttling arrangement 6.
In the utility model, temperature sensor 2 is positioned at compressor 1 exhaust outlet side, and temperature sensor 2 output action is in hydrojet magnetic valve 4, and the opening and closing of hydrojet magnetic valve 4 can control the second throttling arrangement 6 and carry out hydrojet, avoids compressor 1 air entry hypertonia.
Pressure sensor 8 is positioned at compressor 1 air entry side, and pressure sensor 8 output action, in adjusting magnetic valve 9, can adjust the opening and closing of magnetic valve 9 can control the energy adjustment of energy regulator 10, and the regulated quantity of energy regulator 10 is mechanical adjustable device.
When evaporimeter 7 side, load diminishes, cold-producing medium evaporation not exclusively, pressure of inspiration(Pi) can reduce, when pressure sensor 8 records compressor 1 pressure of inspiration(Pi) lower than a certain setting value, magnetic valve 9 can be adjusted to open, from compressor 1 exhaust outlet gaseous refrigerant out through magnetic valve 9 can be adjusted, capacity adjusting valve 10, finally get back to compressor 1, reduce because exhaust bypass causes compressor 1 to export energy, but along with evaporimeter 7 side load reduces further, the bypass amount of capacity adjusting valve 10 increases, compressor 1 suction side temperature can increase, when the temperature that temperature sensor 2 records compressor 1 exhaust side is higher than design temperature certain value, hydrojet magnetic valve 4 is opened, after condenser 3, liquid refrigerant is through hydrojet magnetic valve 4 and the second throttling arrangement 6, finally get back to the air entry of compressor 1, suction temperature reduces, compressor 1 normal operating condition can be ensured.
Above embodiment is not limited only to protection domain of the present utility model, all modify based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
