As shown in fig. 1.
An integrated water source multi-output refrigerating system comprises an outdoor unit and an indoor unit.

The refrigerant circulation loop in the outdoor unit comprises the following connections: the exhaust port of the compressor 1 is connected with the D port of the four-way valve 3 after passing through the oil separator 2, and the suction port of the compressor is connected with the outlet of the gas-liquid separator 4; an S port of the four-way valve 3 is connected with an inlet of the gas-liquid separator 4, a C port of the four-way valve is connected with a first refrigerant end of an outdoor heat exchanger I5, and an E port of the four-way valve is connected with a second refrigerant end of an outdoor heat exchanger II 7; a second refrigerant end of the outdoor heat exchanger I5 is connected with a first refrigerant end of the outdoor heat exchanger II 7; and an outdoor electronic expansion valve 6 is arranged at a first refrigerant end of the outdoor heat exchanger II 6.
The water path of the outdoor heat exchanger I5 is communicated with a cooling water source to form a cooling water circulation loop, so that the heat exchange requirement of the outdoor heat exchanger I5 is met. Simultaneously, the port in this water route is equipped with respectively and is equipped with stop valve I10 and stop valve II11, is convenient for control the break-make of cooling water, easy to assemble and maintenance.
The indoor unit comprises a fluorine-cooling indoor unit and a water-cooling indoor unit.
The fluorine cooling indoor unit comprises a plurality of indoor unit heat exchangers 17 which are connected in parallel with each other. The first end of the indoor unit heat exchanger 17 passes through the stop valve III12 and then is connected to the pipeline between the outdoor unit heat exchanger I5 and the outdoor unit heat exchanger II7, and the second end thereof is connected to the E end of the four-way valve 3, so that the fluorine system communication between the fluorine cooling indoor unit and the outdoor unit is realized. Meanwhile, the first end of each indoor unit heat exchanger is provided with an indoor unit electronic expansion valve 16, throttling operation or on-off control can be performed on the refrigerant, and different use requirements are met.
The connecting pipeline of the outdoor unit and the fluorine cooling indoor unit is respectively provided with a stop valve III12 and a stop valve VI15, so that the on-off of a refrigerant loop can be controlled, and the installation and the maintenance are convenient.
The water cooled indoor unit includes a plurality of fan coil heat exchangers 18 connected in parallel with each other. Two ends of the fan coil heat exchanger 18 are communicated with a water channel of the outdoor unit heat exchanger II7 to form a chilled water circulation loop, so that chilled water generated by the outdoor unit heat exchanger II7 is introduced into the fan coil heat exchanger, and the chilled water exchanges heat with indoor air under the action of a fan, thereby realizing refrigeration. The water channel ports of the outdoor unit heat exchanger II7 are respectively provided with a stop valve IV13 and a stop valve V14, so that the on-off of the water channel can be controlled, the installation and the maintenance are convenient, and different use requirements can be met.
And the cooling water circulation loop and the chilled water circulation loop are respectively provided with a water pump I8 and a water pump II9, so that water flow can be promoted, and the operation efficiency is improved.
The working process of the invention is as follows:
when the output source is the fluorine cooling indoor unit, the stop valve III and the stop valve VI are opened, the stop valve V and the stop valve VI are closed, and the electronic expansion valve of the outdoor unit is closed. At the moment, the refrigerant flowing out of the compressor flows into the fluorine-cooling indoor unit after being condensed by the outdoor unit heat exchanger I, is throttled by the indoor unit electronic expansion valve, evaporates and absorbs heat in the indoor unit heat exchanger to realize indoor refrigeration, and then flows back to the compressor to finish circulation.
When the output source is the water cooling indoor unit, stop valve III and stop valve VI are closed, stop valve V and stop valve VI are opened, water pump II is opened, and outdoor unit electronic expansion valve is opened to play the throttling role. At the moment, the refrigerant discharged by the compressor is condensed by the outdoor unit heat exchanger I to release heat, throttled by the outdoor unit electronic expansion valve, flows into the outdoor unit heat exchanger II to evaporate and absorb heat, and cools the chilled water. Then, the compressor is returned to the next cycle. And the cooled chilled water flows into the fan coil heat exchanger under the action of the water pump II and exchanges heat with indoor air under the action of the fan, so that indoor refrigeration is realized.
When the output source is the fluorine cooling indoor unit and the water cooling indoor unit, the stop valve III, the stop valve IV, the stop valve V and the stop valve VI are all opened, and the electronic expansion valve of the indoor unit is opened and plays a role in throttling. At the moment, the refrigerant discharged by the compressor flows through the outdoor heat exchanger I to be condensed and released heat, then the refrigerant is divided into two parts, one part of the refrigerant flows into the fluorine-cooling indoor unit, and after the refrigerant is throttled by the indoor unit electronic expansion valve, the refrigerant is evaporated and absorbed in the indoor unit heat exchanger, so that refrigeration is realized. And the other part of the refrigerant flows into an outdoor unit heat exchanger II after being throttled by an outdoor unit electronic expansion valve, is evaporated and absorbs heat, and cools chilled water. Then, after the two parts of refrigerants are merged, the refrigerants flow back to the compressor, and the circulation is completed. The cooled chilled water flows into a fan coil heat exchanger of the water-cooled indoor unit to exchange heat with indoor air, so that refrigeration is realized. Therefore, the fluorine cooling indoor unit and the water cooling indoor unit work simultaneously.
The invention can integrate two output source modes of fluorine cooling and water cooling into a set of system, and unify the input source of the refrigerating system as the water source, thereby not only facilitating the user to select different output sources according to the requirement, but also facilitating the maintenance or the reconstruction of the system and fully meeting the market requirement.
The parts not involved in the present invention are the same as or can be implemented using the prior art.
