Abstract
A kind of ultralow ambient temperature cooling by wind, this utility model relate to a kind of can at ultralow ambient temperature 25 DEG C the cooling by wind of safe refrigerating operaton；This utility model to solve the technical problem that be cooling by wind can not at a temperature of ultralow environment normal refrigerating operaton.This utility model solution technical problem be the technical scheme is that air-cooled condenser and condensation fan to be arranged in a good casing of the insulation closed, and air inlet and air outlet on casing install Electric air valve；Two condensing pressure controllers are installed in outlet at air-cooled condenser, by controlling start and stop and the switch of Electric air valve of condensation fan, reach cooling by wind purpose of normal refrigerating operaton at a temperature of ultralow environment.It is mainly used at a temperature of ultralow environment, to run cooling by wind, it is to avoid cool down at ambient temperature higher luck row cooling by wind, and use other type of cooling when low ambient temperature.
Description
Technical field
This utility model relates to a kind of cooling by wind, especially safety can freeze at ultralow ambient temperature-25 DEG C
The cooling by wind run.
Background technology
At present, cooling by wind, when low ambient temperature freezes, is to control condensation fan by condensing pressure controller
Start and stop, when monitoring the stopping pressure that condensing pressure sets less than condensing pressure controller, condensation fan is out of service, by wind
The natural cooling of cool condenser reaches condensation effect；Rise when monitoring condensing pressure, return to condensing pressure controller and set
During fixed startup pressure, recover the operation of condensation fan.But when ultralow ambient temperature reaches operation, condensation fan stops fortune
OK, the natural cooling effect of condenser is fine, and the natural cooling only relying on condenser still reaches to less than the condensing pressure required, machine
Group cannot normal refrigerating operaton.
Summary of the invention
In order to overcome existing cooling by wind can not at a temperature of ultralow environment the deficiency of normal refrigerating operaton, this reality
With novel offer one cooling by wind, this cooling by wind can not only be the most properly functioning, Er Qieneng
Normal refrigerating operaton at a temperature of ultralow environment.
This utility model solves its technical problem and be the technical scheme is that air-cooled condenser and condensation fan installation
In a good casing of insulation closed, the air intake position of air-cooled condenser and the air-out position of condensation fan on casing
Reserved air inlet and air outlet, install Electric air valve at air inlet and air outlet.Air-cooled condenser is installed two condensation pressures
Force controller P1, P2, when condensing pressure controller P1 monitors condensing pressure less than design condensing pressure-2bar, condensating wind
Machine is out of service；When condensing pressure controller P1 monitors condensing pressure higher than design condensing pressure-1bar, condensation fan is extensive
Multiple operation；When condensing pressure controller P2 monitors condensing pressure less than design condensing pressure-4bar, close air inlet and go out
The Electric air valve in air port；When condensing pressure controller P2 monitor condensing pressure higher than design condensing pressure-3bar time, open into
Air port and the Electric air valve of air outlet.By controlling start and stop and the switch of Electric air valve of condensation fan, reach wind-cooled cold-water
Unit is the purpose of normal refrigerating operaton at a temperature of ultralow environment.
The beneficial effects of the utility model are, can run cooling by wind, it is to avoid at ring at a temperature of ultralow environment
Temperature higher luck row cooling by wind in border cools down, and uses other type of cooling when low ambient temperature.Further, control
Mode processed and simple in construction.

Detailed description of the invention
Ultralow ambient temperature cooling by wind in accompanying drawing, its system includes refrigeration system, wind system, water system.System
Cooling system by compressor (1), air-cooled condenser (4), condensing pressure controller P1 (7), condensing pressure controller P2 (8), be dried
Filter (9), expansion valve (10), plate type heat exchanger (11) connect composition with pipeline successively by diagram, and all pipeline heat insulations are good,
Charging refrigerant in system；Compressor (1) is arranged in the compressor box (12) that insulation is good.Wind system is by condenser casing
(5), Electric air valve air inlet valve (6), air-cooled condenser (4), condensation fan (3), Electric air valve outlet valve (2) composition；By air-cooled
Condenser (4) and condensation fan (3) are arranged in a good condenser casing (5) of the insulation closed, at condenser casing
(5) the air intake position of the air-cooled condenser (4) in and the air-out position of condensation fan (3) reserve air inlet and air outlet respectively,
At air inlet, Electric air valve air inlet valve (6) is installed, at air outlet, Electric air valve outlet valve (2) is installed；Air passes sequentially through electronic
Air-valve air inlet valve (6), air-cooled condenser (4), condensation fan (3), Electric air valve outlet valve (2).Water system is by plate type heat exchanger
(11) composition, the top water inlet of plate type heat exchanger (11), bottom water outlet.
Its control mode is, installs condensing pressure controller P1 (7), condensing pressure in the outlet of air-cooled condenser (4)
Controller P2 (8).When condensing pressure controller P1 (7) monitors condensing pressure less than design condensing pressure-2bar, condensating wind
Machine (3) is out of service；When condensing pressure controller P1 (7) monitors condensing pressure higher than design condensing pressure-1bar, condensation
Blower fan (3) resumes operation；When condensing pressure controller P2 (8) monitors condensing pressure less than design condensing pressure-4bar, close
Close the Electric air valve air inlet valve (6) of air inlet and the Electric air valve outlet valve (2) of air outlet；When condensing pressure controller P2 (8)
When monitoring condensing pressure higher than design condensing pressure-3bar, open the Electric air valve air inlet valve (6) of air inlet and air outlet
Electric air valve outlet valve (2).By controlling start and stop and Electric air valve air inlet valve (6), the Electric air valve outlet valve of condensation fan (3)
(2) switch, reaches cooling by wind purpose of normal refrigerating operaton at a temperature of ultralow environment.
