Description
Technical field
A kind of control device for adjusting evaporating temperature in real time according to environment temperature and humidity is the utility model is related to, belongs to system
Cold engineering field.
Background technology
In general supermarket's project, the unit that cold is provided to showcase and freezer is set using fixed pressure of inspiration(Pi)
Value and fixed evaporating temperature control, and this control mode has following several aspect deficiencies：
Using fixed evaporating temperature mode, evaporating pressure is fixed, and this mode is regardless of environment temperature and humidity
Change, the control evaporating temperature of unit is all fixed, and the operational efficiency of unit is low, wastes energy consumption.
When environment temperature and humidity relative reduction, it is not necessary to meet showcase temperature requirements with very low evaporating temperature,
At this moment low evaporating temperature can cause compressor to flog a dead horse and cause frequent start-stop, increase energy consumption, so that freezing system of supermarket
Power consumption of uniting increases.
When environment temperature and of a relatively high humidity, it is necessary to which low evaporating temperature meets showcase temperature requirements, at this moment compared with
High evaporating temperature can cause compressor to be shut down in the case where showcase temperature is not reaching to, so as to cause showcase temperature not
It is good.
Utility model content
The purpose of this utility model is to provide a kind of control for adjusting evaporating temperature in real time according to environment temperature and humidity
Device, more preferable temperature effect can be reached according to showcase demand real time modifying refrigerator evaporating temperature, preferably keep food
Quality.Energy-saving effect is improved, reduces power consumption, is that supermarket is cost-effective.
The utility model solves above-mentioned technical problem by following technological means：
A kind of control device for adjusting evaporating temperature in real time according to environment temperature and humidity of the present utility model, it includes cold
Cabinet and refrigeration unit, connected with air intake duct by feed pipe between the refrigerator and refrigeration unit, set in the refrigeration unit
There is compressor, evaporator is provided with refrigerator, feed pipe and air intake duct are respectively communicated with the inlet and outlet in evaporator, compressor
Pressure of inspiration(Pi) be continuously adjustabe.
The compressor is variable-frequency motor.
Evaporating temperature continuously adjustabe on the evaporator.
The beneficial effects of the utility model are as follows：It can be reached more according to showcase demand real time modifying refrigerator evaporating temperature
Good temperature effect, preferably keep the quality of food.Energy-saving effect is improved, reduces power consumption, is that supermarket is cost-effective.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the utility model structural frames schematic diagram；
Fig. 2 is the utility model experimental data figure.
Embodiment
The utility model is described in detail below with reference to accompanying drawing, as shown in Figure 1, 2：A kind of basis of the present embodiment
Environment temperature and humidity adjust the control device of evaporating temperature in real time, and it includes refrigerator 1 and refrigeration unit 2, the refrigerator 1 and system
Connected between cold group 2 by feed pipe 3 with air intake duct 4, compressor 5 is provided with the refrigeration unit 2, is set in refrigerator 1
There is evaporator 6, feed pipe 3 and air intake duct 4 are respectively communicated with the inlet and outlet of evaporator 6, and the pressure of inspiration(Pi) of compressor 5 is company
It is continuous adjustable.
The compressor 5 is variable-frequency motor.
Evaporating temperature continuously adjustabe on the evaporator 6.
It is that a simple refrigeration system includes refrigerator and unit as shown in Figure 1.At present in typical refrigeration control system
In, the pressure of inspiration(Pi) set point of compressor is fixed, it means that evaporating temperature is fixed.Generally, it is fixed to inhale
Atmospheric pressure set point is in order to meet the refrigeration requirement under 25 DEG C and 60% damp condition.When the reduction of temperature and humidity, outside is entered
Entering the heat of showcase can also be reduced, and rise evaporating temperature also ensures that product temperature is in range of needs in showcase, but rises
High evaporating temperature, the operational efficiency of compressor just improve, and energy consumption just reduces.
As shown in Fig. 2 it is the experiment according to environment temperature and humidity measurement floating control evaporating temperature.Established according to Fig. 1
A set of refrigeration system simulation test, compressor can be 100rps (revolutions per second) from 20rps (revolutions per second), according to environment temperature and
The difference of humidity, run under different temperatures and psychrometric condition, under the premise of commodity all meet temperature requirement in two showcases,
Evaporating temperature is improved as far as possible.From the point of view of test data, refrigerator is in the environment of high-temperature high-humidity, and required evaporating temperature is most
Low, energy consumption is maximum.In the environment of low temperature and low humidity degree, required evaporating temperature avoids the need for very low, energy consumption reduction.
When evaporating temperature raises, the COP of compressor is improved, and helps to save.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
