The operational mode of group.
As shown in Fig. 2 Fig. 2 is the flow of the preferred embodiment of the control method of the double cooling handpiece Water Chilling Units of the utility model
Figure, including step：
S1, the cooling in summer pattern of setting unit, conditioning in Transition Season refrigeration mode and winter refrigeration pattern in Intelligent control cabinet,
And a threshold temperature T1 is set, more preferably, temperature threshold T1 is set and meets 5 DEG C≤T1≤15 DEG C；
S2, when the continuous some days of outdoor sensor in Intelligent control cabinet detect outdoor 27 DEG C of mean temperature T0 ＞, then
Control unit presses cooling in summer mode operation；When continuous some days detect outdoor mean temperature T0≤7 DEG C, then unit is controlled to press
Winter refrigeration mode operation；Remaining situation then controls unit to be run by transition season refrigeration mode.
When Intelligent control cabinet control unit presses cooling in summer mode operation, comprise the following steps：
Leaving water temperature sensors are carried out every 600S to leaving water temperature T2 in S211, double cooling handpiece Water Chilling Units Intelligent control cabinets
Detection, is then judged the size of T2 and T1 by the comparison judgment unit in Intelligent control cabinet；
S212, when T2 ＞ T1 are detected, Intelligent control cabinet control water circulating pump open, two water-through valves close, three water flowings
The first path in valve is opened, alternate path is closed, and chilled water directly enters shell and tube exchanger by water inlet；Opened after 30S
Open axial flow blower；Compressor is opened after 60S, electric energy-saving device is opened big according to degree of superheat T3 is set or turns down valve element, adjusts
Refrigerant flow, so as to adjust refrigeration intensity, more preferably, can set 2 DEG C≤T3≤10 DEG C；
S213, when T2≤T1 is detected, then after 300S is stablized, Intelligent control cabinet control compressor unloading operation, per steady
Unloading amplitude is successively decreased in 10% ratio after determining 600S；Occur T2 ＞ T1 when compressor is in non-100% running status, then by 10% ratio
Example is compressed machine load operating, is reruned after detecting T2 and T1 relations after the stabilization such as each loading 600S；When compressor is unloaded
When being loaded onto 25% running status, if T2≤T1, close compressor closes water circulating pump after 60S, closing axle stream wind after 30S
Machine, the first path of close synchronously T-way water valve.
When Intelligent control cabinet control unit presses conditioning in Transition Season refrigeration mode to be run, comprise the following steps：
Leaving water temperature sensors are carried out every 600S to leaving water temperature T2 in S221, double cooling handpiece Water Chilling Units Intelligent control cabinets
Detection, is then judged the size of T2 and T1 by the comparison judgment unit in Intelligent control cabinet；
S222, when T2 ＞ T1 are detected, Intelligent control cabinet control water circulating pump close, two water-through valves open, three water flowings
The first path in valve is opened, alternate path is opened, and a chilled water part enters shell and tube exchanger after air cooling heat exchanger, separately
A part directly enters shell and tube exchanger by water inlet；Axial flow blower is opened after 30S；Compressor, electronics section are opened after 60S
Energy device is opened greatly or turns down valve element, adjusting refrigerant flow rate according to degree of superheat T3 is set；
During S222, a part of cooling water is cooled down by air cooling heat exchanger, then at T-way water valve with
Another part cooling water converges, and flows into shell and tube exchanger and continues to cool down, and is finally flowed out from after water outlet.
S223, when leaving water temperature T2≤T1 is detected, Intelligent control cabinet control compressor unloading operation after 300S, per steady
Unloading amplitude is successively decreased in 10% ratio after determining 600S；Occur T2 ＞ T1 when non-100% running status, then by 10% scale compression machine
Reruned after detecting T2 and T1 relations after the stabilization such as load operating, each loading 600S；When the operation of compressor unloading to 25%
During state, if T2≤T1, close compressor closes axial flow blower, the first path of close synchronously T-way water valve and after 30S
Two paths.
It can be seen that during S223, combining compressor cooling and the air-cooled type of cooling, ensureing leaving water temperature satisfaction
It is required that on the premise of, the energy consumption of operational outfit is reduced to greatest extent, realize energy-efficient ground operating unit.
When Intelligent control cabinet control unit presses winter refrigeration mode operation, comprise the following steps：
S231, Intelligent control cabinet control compressor are closed, and water circulating pump is closed, in double cooling handpiece Water Chilling Units Intelligent control cabinets
Leaving water temperature sensors are detected to leaving water temperature T2 every 300S, then sentenced by the comparison judgment unit in Intelligent control cabinet
The size of disconnected T2 and T1：
S232, when leaving water temperature T2 ＞ T1 are detected, Intelligent control cabinet control two water-through valves open, T-way water valve first
Path is fully closed, alternate path standard-sized sheet, and chilled water all enters shell and tube exchanger after air cooling heat exchanger；
S233, when leaving water temperature T2≤T1 is detected, axial flow blower by platform close unloading operation, often stablize 300S after unload
Carry 1 amplitude taper；Occur T2 ＞ T1 when non-100% running status, then open loading fortune by platform by 1 amplitude axial flow blower
OK, reruned after detecting T2 and T1 relations after the stabilization such as each loading 300S；When being offloaded to an axial flow blower still T2≤T1,
Axial flow blower is closed in then control, closes two water-through valves, the alternate path of close synchronously T-way water valve.The now portion in refrigeration unit
Part in addition to Intelligent control cabinet and cooling-water temperature sensor and air-temperature sensor, all in closed mode, then per 300S duplicate detections T2
With T1 relations, when meeting T2 ＞ T1 DEG C, then started shooting again by winter refrigeration operation.
It can be seen that in the winter time in refrigeration mode, cooling water is to be cooled down by air cooling heat exchanger completely, and refrigerant is followed
Each equipment in ring path is all in closed mode, energy consumption when being run in the winter time It greatly reduces unit, and unit exists
Step S233 processes, on the premise of leaving water temperature meets requirement, reduce the operation of axial flow blower ground to greatest extent, further subtract
Energy consumption is lacked.
In sum, double cooling handpiece Water Chilling Units pipe shell type heat exchanges that the utility model is provided are with the air-cooled side for exchanging heat and being combined
Formula, by Intelligent control cabinet according to annual Different climate condition, reasonable selection cooling water unit operational mode, control unit is efficient
Energy-saving run, solve in the prior art handpiece Water Chilling Units can not according to annual Different climate carry out efficiently, energy-saving run, cause cold
The problem that water units consumption is higher, operating cost is larger, reduces energy loss, reduces energy consumption, also reduces unit operation
Cost, finally for enterprise reduces production cost, brings economic benefit.
It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model
The protection domain that profit is required.
