For cooling supply.
In night ice-make mode, the second control valve 14, the 4th control valve 16 and the 5th control valve 17 are in close state,
When the first temperature sensor 9 detects that the ethylene glycol inlet side temperature of plate heat exchanger 4 (may generally be lower than a desired temperature
1-3 DEG C) when, chilled water pump 8 is started by controller 11,5 cooling supply of fan coil pipe while ice making.Due to night air conditioning terminal
5 load of fan coil it is much lower compared with daytime, many heats cannot be replaced, it is possible that making the ethylene glycol of plate heat exchanger 4
Side-entrance and outlet temperature are close, are likely to result in the second pipeline 7 at plate heat exchanger 4 at this time and freeze, board-like when detecting
When the ethylene glycol side outlet side temperature and inlet side temperature of heat exchanger 4 are close, controller 11 can start the alarm of alarm 12, can examine
It looks into whether the second control valve 14, the 4th control valve 16 and the 5th control valve 17 damage or be not closed completely, is replaced or closed.
The utility model can effectively prevent the plate heat exchanger of Double-working-condition air-conditioning system to freeze, using duplicate protection, ice-reserving
When the leaking liquid amount of tank to plate heat exchanger is smaller, start chilled water pump, the fluid of operation the second pipeline of plate heat exchanger enters wind
Machine coil pipe refrigeration avoids water in the second pipeline from being frozen in since the low-temperature refrigerant temperature of the first pipeline is too low and lead to the
The tube wall of two pipelines bursts；When the leaking liquid amount of ice storage tank to plate heat exchanger is larger, alarm can be started, check leakage reason,
Corresponding control valve is replaced or closed in time, both can guarantee the ice-reserving refrigeration unit night operation ice making mould of Double-working-condition air-conditioning system
Formula, and be avoided that due to freezing at plate heat exchanger and lead to not operate normally, guarantee is provided safely for system, is conducive to
Popularization and application of the Double-working-condition air-conditioning system in refrigeration industry.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art work as can make various corresponding changes and modifications, but these according to the utility model
Corresponding changes and modifications all should belong to the protection scope of the utility model the attached claims.
