The utility model comprises two loops based on the solution type cold and hot water unit of cooling tower: refrigerant loop and solution loop.Concrete grammar of the present utility model is:
During based on the solution type cold and hot water unit refrigerating operaton in summer of cooling tower: refrigerant loop is that the refrigerant gas of low-temp low-pressure is sucked by compressor from gas-liquid separator, becoming the HTHP superheated vapor after the compression discharges, enter in second heat exchanger through cross valve, cold-producing medium is emitted heat, carry out condensation and become liquid, again successively through second check valve, first magnetic valve enters the solution regenerator, this moment, the solution regenerator played the effect of subcooler, liquid refrigerant carries out heat exchange with cooling water therein, refrigerant liquid temperature further reduces, and becomes subcooled liquid.After crossing cold cold-producing medium and coming out from the solution regenerator through becoming the gas-liquid two-phase of low-temp low-pressure behind reservoir, filter, the electric expansion valve, again through entering first heat exchanger behind the 3rd check valve, the cold-producing medium evaporation of in first heat exchanger, absorbing heat, produce cold water, becoming overheated gas after cold-producing medium evaporates fully comes out to enter gas-liquid separator through cross valve from first heat exchanger, and then be inhaled into compressor, thus finish kind of refrigeration cycle, produce cold water.All the other all are full of cooling water except that the solution reservoir in the solution loop at this moment, and solution is stored in the solution holder, does not participate in the circulation of solution loop.After cooling water comes out from cooling tower in solution loop, directly enter variable frequency pump by the 4th magnetic valve, after the variable frequency pump pressurization, cooling water enters the electric three passes control valve, the electric three passes control valve enters the solution regenerator with whole cooling waters, cooling water in the solution regenerator with the cold-producing medium heat exchange, the cooling refrigeration agent, make cold-producing medium cold excessively, cooling water temperature raises a little, and cooling water enters second heat exchanger after the solution regenerator comes out, absorb heat condensation of refrigerant is become liquid, enter cooling tower after self temperature further raises and carry out the wet exchange of heat, flow out like this circulation after cooling water temperature reduces once more from cooling tower with air.
During based on the operation of the solution type cold and hot water unit winter heating of cooling tower, refrigerant loop is to discharge through cross valve after the refrigerant gas of low-temp low-pressure in the gas-liquid separator is sucked, compresses by compressor to enter first heat exchanger, cold-producing medium is emitted heat in first heat exchanger, produce hot water, simultaneously self be condensed into liquid, after liquid refrigerant comes out from first heat exchanger, enter the solution regenerator through first check valve, first magnetic valve, cold-producing medium carries out heat exchange with solution therein, cold-producing medium is emitted heat, temperature reduces, and realizes cold.After crossing cold cold-producing medium and coming out from the solution regenerator, successively by reservoir, filter, electric expansion valve, entered in second heat exchanger through the 4th check valve with gas-liquid two-phase after the electric expansion valve throttling step-down, in second heat exchanger, evaporate heat absorption, cold-producing medium evaporates the back fully and enters gas-liquid separator from second heat exchanger cross valve that comes out to flow through, sucked, compress by compressor once more at last, so circulation.Charging solution in the solution loop this moment, solution enters the solution reservoir by the 3rd magnetic valve after cooling tower comes out, again through entering variable frequency pump behind the 5th magnetic valve, solution enters the electric three passes control valve after the variable frequency pump pressurization, solution is divided into two parts, a part enters the solution regenerator, solution is transpiring moisture therein, concentration improves, solution mixes with another part solution through the regeneration back, enters second heat exchanger, carries out heat exchange with cold-producing medium, emit heat, self temperature reduces, and solution enters cooling tower after second heat exchanger comes out, and (solution temperature is lower than air themperature to the solution of high concentration low temperature, the partial pressure of water vapor of solution is smaller or equal to airborne partial pressure of water vapor) in cooling tower, carry out the wet exchange of heat with air, solution absorbs heat from air, water in air steam condenses in solution, and the temperature of solution raises, concentration decreases, and flows out from cooling tower then to participate in circulation once more.
