Abstract
The utility model relates to a power-off and water-break anti-freezing protector of a lithium bromide absorbing cooling and heating water machine set, which belongs to the field of a central air conditioner machine set. The utility model comprises a condenser (1), an evaporator (3), an absorber (4) and a refrigerant water throttling device which is connected with the condenser (1) and the evaporator (3). The utility model is characterized in that the refrigerant water throttling device is connected with a valve, and the other end of the valve is connected with a water outlet pipe. The power-off and water-break anti-freezing protector of a lithium bromide absorbing cooling and heating water machine set of the utility model effectively avoids an accident of refrigerant water icing to freeze chilled water in a copper pipe of the evaporator to expand the copper pipe to damage the copper pipe.
Description
Technical field
The utility model belongs to the central air-conditioning unit, is specifically related to a kind of lithium bromide absorption cold/hot water unit.
Background technology
Lithium bromide absorption cold/when the hot water unit is cut off the water supply, system's chilled water does not flow, and the target type meter differential pressure controller on the refrigerant water pipe sends signal, and control system will be closed thermal source (burner/steam/heat water), cryogenic fluid pump is out of service, generating pump input dilution operation; During outage, when unit powering-off state occurs in running, control system will be closed thermal source (burner/steam/heat water) cryogenic fluid pump, and generating pump is out of service.When above two kinds of situations occurring, will be from water as refrigerant that lithium bromide absorption cold/hot water unit condenser produces by spray equipment spray at lithium bromide absorption cold/above the hot water unit evaporimeter copper pipe, continuation is freezed to immobilising chilled water limited in the evaporimeter copper pipe, very easily produce coolant-icing and the chilled water in the evaporimeter copper pipe is freezed, cause the major break down of the bad copper pipe that expands.
The utility model content
Technical problem to be solved in the utility model is in order to overcome above-mentioned defective, and chilled water freezes in a kind of device copper pipe that can avoid evaporating lithium bromide absorption cold/hot water unit anti-freeze protection device of cutting the supply of water and electricity is provided.
In order to solve the problems of the technologies described above; the technical scheme that the utility model adopted is: lithium bromide absorption cold/hot water unit anti-freeze protection device of cutting the supply of water and electricity; the water as refrigerant throttling arrangement that comprises condenser, evaporimeter, absorber, links to each other with evaporimeter with condenser; its water as refrigerant throttling arrangement connects valve, and the other end of valve connects outlet pipe.The water as refrigerant throttling arrangement is U type throttle pipe or restricting orifice.
Described lithium bromide absorption cold/hot water unit anti-freeze protection device of cutting the supply of water and electricity, its valve is a magnetic valve.
Described lithium bromide absorption cold/hot water unit anti-freeze protection device of cutting the supply of water and electricity, its valve is a stop valve.
Described lithium bromide absorption cold/hot water unit anti-freeze protection device of cutting the supply of water and electricity, its outlet pipe links to each other with evaporimeter.
Described lithium bromide absorption cold/hot water unit anti-freeze protection device of cutting the supply of water and electricity, its outlet pipe links to each other with absorber.
Compared with prior art the beneficial effect that the utility model had is: the utility model lithium bromide absorption cold/hot water unit chilled water anti-freeze protection device of cutting the supply of water and electricity is cut off the water supply, when cutting off the power supply water as refrigerant is directly fed absorber or evaporimeter at unexpected chilled water, avoided effectively coolant-icing and to the chilled water in the evaporimeter copper pipe freeze, the generation of the bad copper pipe accident that expands.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of another embodiment of the utility model.
The specific embodiment
No. 2 spray equipments of 1 condenser 3 evaporimeters 4 absorbers 5 cryogenic fluid pumps 6 generating pumps 7 outlet pipes 8 magnetic valve 9U type throttle pipes 10 restricting orifices
As shown in Figure 1: link to each other by U type throttle pipe 9 between condenser 1 and the evaporimeter 3, connect magnetic valve 8 between U type throttle pipe 9 and the absorber 4, when unexpected generation chilled water cut off the water supply, when cutting off the power supply, magnetic valve 8 is opened, the water as refrigerant that produces from condenser 1 enters absorber 4 through outlet pipe 7, no water as refrigerant spray above evaporimeter 3 copper pipes, thereby coolant-icing can not take place and to the bad copper pipe accident of freezing, expand of the cold water in evaporimeter 3 copper pipes.
As shown in Figure 2: link to each other by restricting orifice 10 between condenser 1 and the evaporimeter 3, connect magnetic valve 8 between restricting orifice 10 and the absorber 4, when unexpected generation chilled water cut off the water supply, when cutting off the power supply, magnetic valve 8 is opened, enter the water as refrigerant liquid capsule of evaporimeter 3 through outlet pipe 7 from the water as refrigerant of condenser 1 generation, no water as refrigerant spray above evaporimeter 3 copper pipes, thereby coolant-icing can not take place and to the bad copper pipe accident of freezing, expand of the cold water in evaporimeter 3 copper pipes.
