Abstract
The utility model discloses a low-temperature water source hot pump units belonging to air conditioning apparatus, which comprises a water source hot pump and a segregating heat exchanger. An ethylene glycol solution circulation pipe with a low-temperature coldness-carrying agent circulating water pump is arranged between the water source hot pump and the segregating heat exchanger. One side of the segregating heat exchanger is connected with a water supply pipe and a return pipe, which are provided with a diving pump and are communicated with the low-temperature water source. The utility model separates the low-temperature water source and the water source hot pump via the ethylene glycol solution circulation system, thereby resolving the water source hot pump freezing problem because of the low-temperature water. The water source hot pump can be applicable to the low-temperature water source with a temperature of zero degrees centigrade or so, thereby extending the application area of the water source hot pump air conditioning apparatus greatly.
Description
The utility model relates to air-conditioning equipment, is a kind of low-temperature water source source pump specifically, is particularly suitable for cold district low-temperature water source environment and uses.
Water source heat pump air-conditioner equipment is more and more applied by people widely because of advantages such as its energy-saving and environmental protection.But present water source heat pump units can only be used for low-temperature water source more than 6 ℃ mostly because of its problem that freezes, and at some cold districts, winter, ground temperature had only 3 ℃-5 ℃, be positioned at ocean, the lake of this area, the deep layer water temperature in river has only about 0 ℃ winter, has greatly limited the popularization and application of water source heat pump air-conditioner unit.
The purpose of this utility model is at the problems referred to above, and a kind of water source heat pump units that can extract 0 ℃ of left and right sides low-temperature heat source is provided, so that water source heat pump units can be applied more at large.
The technical scheme that realizes above-mentioned purpose is: a kind of low-temperature water source source pump that includes water resource heat pump and isolate heat exchanger, between connecting the opposite side of side and the secondary water side of isolating heat exchanger, relative water source heat pump air-conditioner end-equipment is provided with the glycol water circulation line that disposes low temperature refrigerating medium water circulating pump, be connected with feed pipe and the return pipe that passes to low-temperature water source in a water side of isolating heat exchanger, the inlet end of its feed pipe is equipped with immersible pump.
The utility model is being isolated the configuration glycol water circulatory system between heat exchanger and the water resource heat pump, low-temperature water source is directly directly contacted with water resource heat pump, solved the water resource heat pump that causes because of the water at low temperature problem that freezes, make water resource heat pump can be applicable to low-temperature water source about 0 ℃, improved the range of application of water source heat pump air-conditioner equipment greatly.
Accompanying drawing is this low-temperature water source source pump configuration structure schematic diagram.
The utility model is described in further detail below in conjunction with drawings and Examples:
As accompanying drawing, this low-temperature water source source pump includes water resource heat pump 1 and isolates heat exchanger 3, between water resource heat pump 1 and isolation heat exchanger 3, be provided with the glycol water circulatory system pipeline 4 of configuration low temperature refrigerating medium water circulating pump 2, be connected with feed pipe 5 and the return pipe 6 that passes to low- temperature water source 8 and 9 in a water side of isolating heat exchanger 3, be equipped with immersible pump 7 in the inlet end of feed pipe 5.
The low-temperature water source 8 that the present embodiment accompanying drawing provides and 9 is underground wet well and back water well, and in the specific implementation, its low-temperature water source also can be water sources such as ocean, lake, river.
Employed refrigerating medium ethylene glycol has the advantage of not corroding the unit metallic conduit in this low-temperature water source source pump.Its freeze-coagulating point temperature reduces with the increase of glycol concentration.The relation of glycol water concentration and freezing point such as following table:
| Glycol concentration (volume ratio %) | 0 | 10 | 20 | 30 | 40 |
| Freezing point temperature (℃) | 0 | -3.7 | -8.9 | -16.0 | -25.5 |
When this unit uses in reality, should adjust the flow of water pump 7, make return pipe 6 not occur freezing to be as the criterion, increase supply backwater temperature difference as far as possible, to save the power consumption of water pump 7.Glycol concentration in the ethylene glycol pipeline 4 should be by the lower slightly 10 ℃ of left and right sides proportionings of actual motion water temperature, in case freezing accident takes place.
