Supply-water pump M3
Under the situation that device is opened, when being timed lock machine, supply-water pump M3 stops output (Chinese prompt arrearage on the control panel), press acknowledgement key, supply-water pump M3 startup.Must difference timed power on/off every day and timed locking machine.At this moment, device work is after 3 hours, all lockings, and it is also invalid press acknowledgement key once more, Chinese prompt on the control panel: need personnel of producer or the dealer eliminating of showing up.By one after the other in per 8 hours operation, to prolong the service life of pump.
Chilled water circulating pump M
Central air-conditioning is opened, and chilled water circulating pump M promptly starts and is considered as refrigeration or system is warm.By one after the other in per 8 hours operation, to prolong the service life of pump.
Full recuperation of heat is a heat-circulation type modularization central air-conditioning
The suction temperature sensor
Suction temperature sensor HW is used for detecting the temperature (this temperature divides refrigeration mode and heat pump mode to be provided with, and 45 ℃-60 ℃ of scopes are set, and return difference is provided with 2 ℃-5 ℃ of scopes) of return-air.Suction temperature refers to the suction temperature after the process heat exchanger carries out heat exchange.Each unit of suction temperature sensor HW must be installed.Refrigeration mode detects: suction temperature sensor HW is lower than refrigeration mode the fan that stops off-premises station 2 when temperature subtracts the return difference temperature is set; Be higher than and open off-premises station 2 fans when temperature is set.Heat pump mode detects: suction temperature sensor HW is higher than and stops off-premises station 2 fans when heat pump mode is provided with temperature, open relief valve 4, when suction temperature is lower than heat pump mode and temperature is set subtracts the return difference temperature, open off-premises station 2 fans, close relief valve 4 (delivery temperature is lower than 105 ℃, under the normal situation of high-voltage switch gear).As adopt electric expansion valve, then the available electron expansion valve is regulated to replace relief valve 4.
Defrost temperature sensor SW
Defrost temperature sensor SW must install.When off-premises station 2 was worked with air conditioning mode, defrosting was just determined by indoor set, so the defrost temperature sensor sensor of this moment does not participate in work.
When off-premises station 2 was worked in the compressor mode, defrosting was determined by the Centralized Controller of central air-conditioning.The defrost temperature sensor participation work of this moment.As adopt electric expansion valve, then the available electron expansion valve is regulated, the standard-sized sheet Defrost mode.
Height pressure measuring ability
High voltage protective switch GY/ low tension switch DY detects the high/low pressure be used for detecting compressor 1 respectively.
High voltage protective switch GY: disconnect when detecting the high voltage protective switch, stop fan, open relief valve 4 (or electronic expansion valve opening adjustment), it is normal that high pressure recovers, and opens fan, closes relief valve 4 (or recovering electronic expansion valve opening).
Low tension switch DY: disconnect when detecting low tension switch, stop heat pump mode, it is normal that low pressure is recovered, and opens heat pump mode.Continuous quadratic or continue low-voltage variation to occur more than 2 minutes in 30 minutes, described compressor quits work, and newspaper failure code and warning.
When high pressure took place, compressor 1 was not related to, and relief valve 4 is opened.Withdraw from high pressure, then relief valve 4 cuts out.When the indoor set mode of operation in refrigeration and when heating mode, relief valve 4 is not worked.
Suction temperature sensors X W
Can be used as the parameter of electronic expansion valve regulation.
Flow sensor SQ1
The flow through cool water quantity of interchanger of detection is as the key parameters of debugging apparatus.
Leaving water temperature sensor W4
Detect coolant-temperature gage, as the key parameters of debugging apparatus.
Condenser temperature sensor W3
Detect the temperature of chilled water.
Chilled water water flow switch SL3
Chilled water circulating pump M opens, and triple valve F opens to heat exchanger H1 direction, and during W3≤W1 and this water flow switch when connecting, this compressor could continue to move, otherwise, must stop and showing failure code and warning.
Chilled water water flow switch SL4
Chilled water circulating pump M opens, and triple valve F opens to the bypass direction, when this water flow switch is switched on, enters the heat pump mode operation after this compressor could be delayed time according to demand, otherwise, must stop and showing failure code and warning.
Triple valve F
When refrigeration or when hot W2 reach to set and put, all compressors cut out, triple valve F current by-passing direction is opened, chilled water circulating pump M works on, chilled water water flow switch SL4 is switched on, chilled water water flow switch SL3 disconnects, and as W2 during near capping, opens by the platform unit according to the W2 feedback information.At this moment, the triple valve F water heat exchanger H1 direction that flows away is opened, and chilled water water flow switch SL3 connects, and chilled water water flow switch SL4 disconnects.
Refrigeration or when heating, descending as conventional moisturizing water level S1 (height of water formula up and down) needs moisturizing.As long as a compressor is arranged in the system in refrigeration, other compressor is in holding state, open conventional moisturizing magnetic valve D1 and begin moisturizing, the compressor that is not enabled in holding state enters heat pump mode, when water level drops to emergency water compensating water level S2 (height of water formula up and down), the compressor that is enabled in holding state by platform enters heat pump mode instant heating product water.Rise as the W2 temperature this moment.Need open compressor cooling, then start the compressor starts refrigeration that does not enter heat pump mode, as all entering heat pump mode, then according to the size of W2 from setting value, decision stops the platform number that heat pump enters refrigeration compressor.Stopped preparing the compressor time-delay of system when cold after 3 minutes, started refrigeration, when W3=W1, the triple valve F water heat exchanger H1 direction that flows away is opened.
When chilled water circulating pump M started, triple valve F opened to interchanger H1 direction, and during W3=W1, this moment, chilled water water flow switch SL3 must connect, and this compressor is operation normally, otherwise then closes this compressor.Incoming call after having a power failure, triple valve F must open to the bypass direction, and the compressor time-delay started by demand after 3 minutes.
Annotate: delay time the back when refrigeration mode is changed from heat pump mode, cross valve 3 is stuck, do not change to, during this compressor start, be hot water in the condenser H1, sent the refrigeration signal this moment, compressor also is activated simultaneously, detection W3 keeps former temperature or is also heating up, simultaneously, and the data when the detected data of defrost temperature sensor still are heat pump mode.As in moisturizing or there is recirculated water to pass through, electric current does not then have big variation, as does not have moisturizing or have recirculated water to pass through, and electric current then can rise rapidly, and answer stoppage protection and report this compressor fault and warning this moment.
Electric expansion valve (two-way shutoff valve 6)
Refrigeration or adjust its aperture by compressor 1 suction temperature when heating, the mark condition is not adjusted standard-sized sheet during defrost for 15 ℃ ± 2 ℃.
Three mutual inductors connect three and are 380V, connect 2 and are 220V.
