Description

The high accuracy cooling-water machine
Technical field
The utility model belongs to the cooling-water machine field.
Background technology
In water resource deficient day by day today, using water wisely, cycling use of water are constantly put on agenda.Because all about ± 2 ℃, control form commonly used is just to change " opening " according to water temperature " to stop " compressor to cooling-water machine precision commonly used, do like this that not only control accuracy is poor, and can cause compressor damage because of the high frequent start-stop, reduce the cooling-water machine life-span.Such cooling-water machine can only be used for general industry cooling and civilian central air-conditioning etc.And in the accurate measurements such as X-ray tube, photomultiplier tube and laser instrument of scientific research field, needing more precise and stable measurement environment, this environment just needs more high-precision cooling-water machine to provide.
The utility model content
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of high accuracy cooling-water machine is provided.
Technical scheme: the high accuracy cooling-water machine, two-layer about being divided into, top of the upper layer is condensation fan (1), is ring-like condenser (3) all around, there are compressor (5), liquid reservoir (8), filter, expansion valve (9) and electric appliance control box (4) in the centre; Water tank (6) is arranged at the bottom, evaporimeter (11), water pump (7), outlet pipe (13) and water inlet pipe (14), wherein, compressor (5) exhaust outlet links to each other with condenser (3), the other end of condenser (3) connects liquid reservoir (8), liquid reservoir (8) outlet connects filter, filter (9) links to each other with expansion valve (10) supply opening, expansion valve (10) outlet is connected on evaporimeter (11) inlet tube, expansion valve (10) temperature-sensitive bag is tied up on the outlet of evaporimeter (11), evaporimeter (11) outlet is got back on the compressor (5), water tank (6) water outlet links to each other with water pump (7) water inlet, the water inlet of using instrument is received in the water outlet of water pump (7), uses instrument used beat water and gets back to water tank (6) water return outlet.
Above-mentioned cooling-water machine is connected a pipeline that enters the mouth towards the evaporimeter (11) near expansion valve (9) rear end as bypass circulation at compressor (5) exhaust outlet, adds magnetic valve (12) in bypass circulation, detects water temperature with temperature sensor in the cooling-water machine outlet.Both can the signal of telecommunication be fed back PU (central processing unit) and PID (PID) adjusting back discharge signal control magnetic valve start-stop, thereby the amount of control bypass hot gas is to reach the purpose of accurate control water temperature according to the minor variations of water temperature.
Operation principle: in kind of refrigeration cycle, compressor is the superheated vapor of HTHP with the refrigerant vapor compression of low-pressure low-temperature, and enters in the condenser, because the cooling heat dissipation effect of top fan makes overheated refrigerant gas become liquid state by gaseous state gradually.The throttling step-down when flowing through expansion valve of the refrigerant liquid of high normal pressure and temperature becomes the low-temperature low-pressure refrigerant damp steam, and (major part is a liquid, fraction is a steam) enter evaporimeter, vaporization heat absorption in evaporimeter, thereby make with evaporimeter in the recirculated water of air-flow adverse current cooling cooling, by temperature controller and bypath system it is controlled at 20 ℃ ± 0.In 5 ℃, with pump the cold water sucking-off of constant temperature is got to the application instrument to keep its operate as normal, application instrument used beat water gets back to water tank and evaporimeter carries out sending the application instrument again back to after heat exchange, the cooling.
The beneficial effects of the utility model are: can more critically control temperature.
