Description
Technical field
The utility model belongs to art of refrigeration units, is specifically related to a kind of unit refrigeration compressor set.
Background technology
Unit refrigeration compressor set is the visual plant carried out freezing in miniature cold storage and accumulating room.Have energy consumption low, take up an area little, cost performance advantages of higher.But in use there is following shortcoming.Current unit refrigeration compressor set, when worst cold case runs, easily causes delivery temperature to increase because pressure of inspiration(Pi) is low, overheat of compressor is operated, cause compressor fault even high temperature burn.In addition when refrigeration system high pressure hypertonia, compressor can damage by high pressure.And therefore need a kind of unit refrigeration compressor set to solve the problems referred to above, extend compressor service life.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of dependable performance and effectively can prevent the unit refrigeration compressor set of compressor high temperature failure.
The technical solution of the utility model be achieved in that a kind of unit refrigeration compressor set comprise be arranged on body by pipeline connect compressor, air-cooled condenser, filter and fluid reservoir, it is characterized in that, also comprise pressure controller; Compressor exhaust pipe place is provided with temperature sensor, and air inlet pipe place is provided with pressure sensor; Capillary is connected with between described filter and fluid reservoir; Described air-cooled condenser is also provided with the magnetic valve be connected with pipeline; Described pressure controller is electrically connected with compressor and pressure sensor respectively.
Preferably, elementary, intermediate and senior tertiary compressed air filter is provided with in described filter.
Preferably, the air inlet pipe outside of described compressor is also provided with and prevents impurity from entering suction filter.
Preferably, described pressure controller is provided with guidance panel, high pressure gauge and low-pressure meter.
Preferably, described compressor is scroll air compressor.
The utility model solves the defect existed in background technology, has following beneficial effect:
The utility model provides a kind of dependable performance and effectively can prevent the unit refrigeration compressor set of compressor high temperature failure.When temperature sensor detects excessive discharge temperature, release cold-producing medium by magnetic valve and increase capillary and compressor is lowered the temperature, eliminate overheat of compressor and situation about damaging.By increasing pressure controller, during high pressure or when pressure of inspiration(Pi) is too low, compressor being dallied, no longer compressing.And pressure makes compressor operating when dropping to low pressure.Normally worked by above technological means available protecting compressor, extend compressor service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of unit refrigeration compressor set;
In figure: 1-body, 2-compressor, 3-temperature sensor, 4-pressure sensor, the air-cooled condenser of 5-, 6-pipeline, 7-magnetic valve, 8-filter, 9-capillary, 10-fluid reservoir, 11-pressure controller.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of unit refrigeration compressor set as shown in Figure 1, comprise be arranged on body 1 by pipeline 6 connect compressor 2, air-cooled condenser 5, filter 8 and fluid reservoir 10, also comprise pressure controller 11; Compressor 2 blast pipe place is provided with temperature sensor 3, and air inlet pipe place is provided with pressure sensor 4; Capillary 9 is connected with between filter 8 and fluid reservoir 10; Air-cooled condenser 5 is also provided with the magnetic valve 7 be connected with pipeline 6; Pressure controller 11 is electrically connected with compressor 2 and pressure sensor 4 respectively.Elementary, intermediate and senior tertiary compressed air filter is provided with in filter 8.The air inlet pipe outside of compressor 2 is also provided with and prevents impurity from entering suction filter.Pressure controller 11 is provided with guidance panel, high pressure gauge and low-pressure meter.Compressor 2 is scroll air compressor.
The course of work of the present utility model is: air enters compressor 2 by air intake filter and completes compression, compressed air enters in fluid reservoir 10 through pipeline 6 successively and carries out air water and just divide and voltage stabilizing, enter at the beginning of filter 8 pairs of precooling compressed air carry out, in, high three-stage filtration, finally enters and returns compressor 2 after air-cooled condenser 5 pairs of compressed air carry out freeze drying and complete process of refrigerastion.When delivery temperature increases, when the temperature that temperature sensor 3 detects is higher than preset value, then magnetic valve 7 is opened, and releases cold-producing medium and lowers the temperature to compressor 2, reach the delivery temperature of compressor, eliminate the situation of overheat of compressor.Pressure sensor 4 is provided with at air inlet pipe place.Pressure controller 11 makes compressor dally when compressor 2 can be made to reach high pressure, no longer compresses.And pressure makes compressor operating when dropping to low pressure.Pressure sensor 4 detects when compressor 2 pressure of inspiration(Pi) is too low, and the microswitch of the low pressure control section of pressure controller 11 disconnects, and cuts off the current supply circuit of compressor 2, makes compressor shutdown.When pressure sensor 4 detects refrigeration system high pressure hypertonia, the microswitch of high voltage control sections disconnects, and cuts off the current supply circuit of compressor, makes compressor shutdown, damaged to avoid compressor by high pressure.Pressure sensor will regulate, and the start and stop force value on adjustable pressure controller 11 guidance panel regulates numerical value to change start and stop pressure preset value.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
