In the following, technique is described in detail in combined process flow chart:
5.1 water preparation process
The water of underground coal mine water supply pipe by self-contained pressure regulator, stable water pressure in the pressure for meeting filter filtering,
Enter first-stage reverse osmosis filter device by quartz filter, PP cotton filter, active carbon filter, through first-stage reverse osmosis mistake
After filter, be filtered into two-pass reverse osmosis filter device, output pure water is stored in seal-off pressure bucket, can be by system outside
The outlet valve set directly is drunk.Or energy transmission occurs for the casing by being built in evaporator and temperature exchange system, supply it is cold,
Water-heating valve door, the personnel of being supplied to drink.
5.2 refrigeration hydraulic arts
Refrigerant in temperature exchange system passes through the liquid refrigerant that compressor compresses are high temperature and pressure, is sent to by pipeline cold
Condenser, condenser radiate to liquid refrigerant, become the liquid refrigerant of medium temperature high pressure, and liquid refrigerant throttles by expansion valve
Enter evaporator afterwards, since space increases, pressure reduces, the refrigerant vaporization of liquid, (being endothermic process from liquid to gaseous state),
The a large amount of heat in evaporator periphery is absorbed, the heat for the direct drinking being arranged on the outside of evaporator in water jacket is absorbed by evaporator, makes
Direct drinking temperature, which reduces, becomes cold water, and the personnel of can be supplied to drink.In evaporator gaseous refrigerant due to compressor air suction act on,
Compressor is returned to by pipeline and is re-compressed into system circulation.
5.3 heating hydraulic arts
There is a conversion four-way valve in temperature exchange system, by the conversion of four-way valve, makes refrigerant in condenser and evaporation
The evaporation on the contrary, exchange of condenser and evaporator function when realizing refrigeration when the flow direction of device and refrigeration, when refrigeration
Device becomes condenser at this time, by refrigerant be high temperature and pressure liquid, the direct drinking in the water jacket of outside realizes that temperature is handed over
It changes, absorbs heat, realize and direct drinking is heated.
5.4 starting Drinking fountain systems, conversion four-way valve are failure to actuate, and compressor starts refrigerating state work, water temperature drops to 10
DEG C, compressor stops working, and when water temperature >=16 DEG C, compressor restarts refrigeration work.
5.5 starting Drinking fountain systems, control four-way valve are powered and act, and compressor starts heat work status, work as water temperature
65 DEG C are increased to, compressor stops working, and when water temperature≤45 DEG C, compressor restarts heating work.
