Description

Hot water fall connect direct combustion dual effect type lithium bromide absorption type heat pump unit
Technical field
It falls to connect direct combustion economic benefits and social benefits the utility model relates to a kind of suction-type lithium bromide thermal power plant unit more particularly to a kind of hot water Type lithium bromide absorption type heat pump unit.Belong to air conditioner technical field.
Background technique
A kind of previous direct combustion dual effect type lithium bromide absorption type heat pump unit as shown in Figure 1, the unit by evaporator 1, inhale Receive device 2, Direct Fired High Pressure Generator 7, low pressure generator 11, condenser 13, high-temperature heat exchanger 4, low temperature heat exchanger 3, molten Liquid pump 18, cryogenic fluid pump 19, control system(It is not shown in the figure)And pipeline, the valve of connecting components are constituted, when unit is run, with Matched 5 burning fuel of burner of Direct Fired High Pressure Generator 7(Combustion gas, fuel oil)The heat of generation as compensation thermal energy, recycle into The waste heat source the heat of hot water of evaporator 1 out externally provides technique use or heat supplication and consumption water that temperature is higher than waste heat source hot water temperature, It is mainly used in while having the place of low-temperature heat source and medium temperature heat demand.The hot water process of this unit uses positive tandem junction Structure, hot water enter back into condenser after being introduced into absorber heat absorption heating, finally go out unit from condenser.Due to the work of condenser Make pressure, operating temperature is limited to the service requirement of Direct Fired High Pressure Generator cannot be excessively high, cause the hot water of this unit to supply Coolant-temperature gage is lower(Generally less than 50 DEG C), it is only applicable to the lower place of heating water's temperature requirement(Such as floor heating heat supply), it is difficult to Meet to the higher heat demand of heating water's temperature requirement.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of hot water, series connection direct combustion dual effect type lithium bromide is inhaled Receipts formula heat pump unit meets so that hot water outlet temperature is increased to >=60 DEG C to the higher heat demand of heating water's temperature.
What the purpose of this utility model was realized in:A kind of hot water falls to connect direct combustion dual effect type lithium bromide absorption type heat pump Unit, including evaporator, absorber, Direct Fired High Pressure Generator, low pressure generator, condenser, high-temperature heat exchanger, Low Temperature Thermal Exchanger, solution pump and cryogenic fluid pump.Hot water cross over pipe is provided between condenser and absorber, hot water inlet pipe is connected to condensation On device, the hot water of condenser enters absorber by hot water communicating pipe out, and hot water outlet pipe is connected on absorber, and hot water process is Serial flow.
The utility model has the beneficial effects that:
The hot water process of the utility model unit is first from external system, the lower hot water of temperature using serial flow Into condenser, absorber is entered back into after the condensation heat heating of refrigerant vapour is absorbed in condenser.In waste heat water outlet temperature It is higher(Generally greater than 30 DEG C)Application conditions under, by improve evaporator and absorber operating pressure and operating temperature, make Increasing extent of temperature of the hot water in absorber improves, and hot water outlet temperature is increased to >=60 DEG C, with meet to heating water's temperature compared with High heat demand.
Detailed description of the invention
Fig. 1 is previous direct combustion dual effect type lithium bromide absorption type heat pump set structure schematic diagram.
Fig. 2 is the utility model hot water series connection direct combustion dual effect type lithium bromide absorption type heat pump set structure schematic diagram.
Appended drawing reference in figure:
Evaporator 1, absorber 2, low temperature heat exchanger 3, high-temperature heat exchanger 4, burner 5, high-incidence outlet tube 6, direct combustion Type high pressure generator 7, high-incidence inlet tube 8, smoke exhaust pipe 9, refrigerant vapour pipe 10, low pressure generator 11, high temperature water as refrigerant outlet pipe 12, condenser 13, hot water outlet pipe 14, hot water communicating pipe 15, waste heat water outlet pipe 16, remaining hot water inlet tube 17, solution pump 18, Cryogenic fluid pump 19, hot water inlet pipe 20.
Specific embodiment
It to facilitate a better understanding of the utility model, is illustrated by example, these examples belong to the utility model Protection scope, but do not limit the protection scope of the utility model.
Embodiment 1:
The utility model unit as shown in Figure 2, the unit be by evaporator 1, absorber 2, Direct Fired High Pressure Generator 7, Low pressure generator 11, condenser 13, high-temperature heat exchanger 4, low temperature heat exchanger 3, solution pump 18, cryogenic fluid pump 19, control system (It is not shown in the figure)And the hot water that is constituted of pipeline, the valve of connecting components falls to connect direct combustion dual effect type lithium bromide absorption type heat pump Unit is provided with refrigerant vapour pipe 10, high temperature water as refrigerant outlet pipe 12 between Direct Fired High Pressure Generator 7 and low pressure generator 11 Hot water communicating pipe 15 is provided between access condenser 13, condenser 13 and absorber 2.Hot water outlet pipe 14 is connected to absorber 2 On, hot water inlet pipe 20 is connected on condenser 13.
When unit is run, hot water enters condenser 13 through hot water inlet pipe 20, is come from low pressure in condenser 13 Go out condensation 13 after the refrigerant vapour of device 11 and the flash steam heat temperature raising of high temperature water as refrigerant, then enters through hot water communicating pipe 15 Absorber 2.Under the service condition of waste heat water outlet temperature >=30 DEG C, the evaporating temperature of evaporator 1 is at 28 DEG C or more, absorber Solution temperature outside 2 heat exchanger tubes is up to 65 DEG C or more, improves increasing extent of temperature of the hot water in absorber heat exchanging pipe, goes out through hot water The hot water temperature that mouth pipe 14 goes out unit is increased to >=60 DEG C, is able to satisfy the higher heat demand of hot water temperature.
The above content is it cannot be assumed that the utility model specific implementation is only limited to these instructions, for belonging to the utility model For the those of ordinary skill of technical field, in the case where not departing from the utility model concept thereof, it can also make and several simply push away It drills or replaces, all shall be regarded as belonging to the utility model scope of patent protection determined by the appended claims.
