Problems solved by technology
[0003] Due to the temperature limitation of waste hot water, the temperature of hot water produced by heat pumps generally cannot or is difficult to meet the actual needs of direct heating. Basically, it is necessary to configure a peak-shaving boiler to continue heating hot water
Installing both a heat pump and a peak-shaving boiler in a heating station will make the machine room occupy a large area and waste land resources
Moreover, the generator determined by the heat pump according to the nominal working conditions will make the maximum recoverable waste heat of the heat pump basically unchanged during the entire use process. The energy-saving effect can recover more waste heat, and the hot water can only be heated up through the peak-shaving boiler at the back
If the design of the heat pump considers increasing the generator, although more waste heat can be recovered when its working condition improves, it will increase the cost of the heat pump, increase the project investment, and cause investment waste

Embodiment Construction
[0015] figure 2 It is an application example diagram of the first type of lithium bromide heat pump unit with peak heating (hereinafter referred to as the unit) involved in the present invention. The unit consists of a condenser 1, a generator 2, a heat exchanger 3, an absorber 4, and a solution pump 5. Consists of refrigerant pump 6, evaporator 7, peak heater 8, hot water regulating valve 9, control system (not shown in the figure) and pipelines and valves connecting various components. The residual hot water flows through the evaporator 7, the hot water first flows through the absorber 4, and then flows through the condenser 1 and the peak heater 8 in parallel, and the hot water regulating valve 9 adjusts the amount of hot water flowing through the peak heater 8 to drive the heat The source flows through the high voltage generator 2. When the unit is running, the refrigerant water pumped out by the refrigerant pump 6 and sprayed from the top of the evaporator 7 absorbs the...

The invention relates to a first-kind lithium bromide heat pump unit with peak heating, and belongs to the technical field of air conditioner equipment. The first-kind lithium bromide heat pump unit with peak heating comprises a condenser (1), a generator (2), a heat exchanger (3), an absorber (4), a solution pump (5), a refrigerant pump (6), an evaporator (7), a peak heater (8) and a hot water adjusting valve (9). The hot water adjusting valve adjusts the volume of hot water entering the peak heater, and high-temperature refrigerant steam in the generator enters the condenser and the peak heater in parallel. According to the unit, a heat pump and a peak adjusting boiler are combined, the machine room area can be saved, waste heat water heat can be preferably recycled as much as possible,and energy is saved.
Description
technical field [0001] The invention relates to a first-type lithium bromide heat pump unit with peak heating. It belongs to the technical field of air conditioning equipment. Background technique [0002] The existing single-effect type I lithium bromide heat pump (hereinafter referred to as heat pump) such as figure 1 As shown, it consists of condenser 1, generator 2, heat exchanger 3, absorber 4, solution pump 5, refrigerant pump 6, evaporator 7, control system (not shown in the figure) and pipelines connecting various components , composed of valves. The residual hot water flows through the evaporator 7 to cool down; the hot water flows through the absorber 4 and the condenser 1 to raise the temperature; the heat source is driven to flow through the generator 2, releasing heat to heat and concentrate the lithium bromide solution. When the heat pump is running, the refrigerant water pumped out by the refrigerant pump 6 and sprayed from the top of the evaporator 7 absor...
