Described surface water heat exchanger is that enclosed is thrown cast surface water heat exchanger or band Intermediate Heat Exchanger surface water heat exchanger.
As many of the quantity of the described heat pump main frame of a kind of optimal way.
Beneficial effect:
1) the present invention links to each other the air-conditioning side water outlet of heat pump main frame at pipeline with the water inlet of water source side, control valve is set on the pipeline, utilize 40～45 ℃ of hot water of an air-conditioning side bypass part to enter the water source side, mix, improve the inflow temperature of heat pump main frame with the water outlet of surface water heat exchanger.Consider water balance, with pipeline the water inlet of the air-conditioning side of heat pump main frame is connected with water source side water outlet, a valve is set on the pipeline, valve has opens or closes two states.
Surface water source heat pump is in service in the winter time, leaving water temperature in the evaporimeter there is minimum requirements, this is because source pump utilizes the limited ability of water resource heat pump in the leaving water temperature of the main frame water source of heat supply mode side, for preventing to freeze in the evaporimeter in the heat pump main frame, general unit need guarantee that leaving water temperature is more than 4 ℃, and some good units can be reduced to this limit 2 ℃, utilize the temperature difference and certain error to guarantee by 3 degree, the main frame inflow temperature reaches more than 5.5 ℃, and water resource heat pump could normally be opened and stable operation.And in the Changjiang river with to the north of the Changjiang river area, in the winter portion of time, surface water water temperatures such as river, lake, river may be lower than the minimum inflow temperature that source pump requires.For guaranteeing unit normal unlatching and stable operation under kind of situation, system need take necessary assisted heating device.General data is to adopt the traditional heat source device directly to add the scheme that thermal water source's side is intake, and heat pump backheat heat patching device scheme is the reasonable utilization to source pump self energy, guarantees normal unlatching of heat pump and stable operation under unfavorable water temperature.Heat pump backheat heat patching device is rationally to adopt the energy of source pump self as auxiliary thermal source, is different from traditional direct heat protocol, and the energy utilization rate height of system has reduced primary energy or power consumption.
2) auxiliary thermal source only plays the purpose of opening unit in the technology of the present invention, after stable operation is opened by system, electrical heating can be closed, therefore be different from direct heat protocol, the present technique invention can effectively reduce the traditional heat source heating power, promptly reduces the capacity of electrical heating, combustion gas, apparatus for fuel heating.
3) system is simple and reliable, can guarantee unit normal unlatching and stable operation under the low operating mode of surface water temperature fully.
4) the comparable open type water source heat pump system of enclosed water source heat pump system is saved the board-like heat exchanger of a cover.
