Abstract
The utility model relates to a two-stage compressed air heat-pump heater, mainly comprising a low pressure compressor (1), a high pressure compressor (2), an inter-cooler (3), a plate type condenser (4), an outdoor finned evaporator (5), thermal expansion valves (6), (7), a liquid storage tank (8), a drying filter (9), electromagnetic valves (10), (11), (12), (13), (14), a pump (15), a water tank (16) and a connecting pipe. The low pressure compressor and the high pressure compressor can share upper compression ratio under the low temperature, thereby improving compression operating condition and enhancing coefficient of capacity. The inter-cooler flow can increase the refrigerant flow of high pressure condensing end, so heating capacity and heating coefficient are higher than that of common single-stage compressed air heat-pump heater. The two-stage compressed air heat-pump heater is set to be a heat-pump system which can automatically transfer two operating models; that is, under the low temperature, two-stage compressed air heat-pump cycle heating; under the high temperature, common single-stage compressed air heat-pump cycle heating.
Description
Technical field
The utility model relates to the heat-pump hot-water apparatus, specifically a kind of two stages of compression air source hot pump water heater.
Background technology
Ordinary single-stage air source heat pump hot-water heating system can be well used in the areas such as the middle and lower reach of Yangtze River, south China and southwest of China.But, at north cold area, or the bigger area of winter air humidity ratio, decline along with winter temperature, evaporating temperature descends thereupon, and water heater then must be produced the target hot water of higher temperature, the calorific requirement to support the family, this just causes problems, so that has influence on the runnability of Teat pump boiler.
Summary of the invention
The purpose of this utility model provides a kind of two stages of compression air source hot pump water heater, under outdoor low temperature environment, produce hot water by adopting the two stages of compression heat pump cycle mode of heating, it utilizes the high-low pressure two-stage compressor to share the required higher compression ratio of operation under the low temperature environment, thereby improved the compression operating mode, improved the gas transmission coefficient, and be aided with the refrigerant flow that the intercooler flow process increases the high pressure condensation end, make heating capacity and heating efficiency obtain bigger raising with respect to ordinary single-stage compressing hot pump water heater; And when outdoor environment temperature was higher, by the switching of magnetic valve, device can adopt single stage compress heat pump cycle mode to produce hot water.
The purpose of this utility model can reach by following measure:
A kind of two stages of compression air source hot pump water heater, by compressor, plate-type condenser, outdoor finned-tube evaporator, heating power expansion valve, magnetic valve, water tank, water pump is formed, and it is characterized in that: low-pressure stage compressor (1) air intake duct links to each other with outdoor finned-tube evaporator (5); Low-pressure stage compressor (1) blast pipe connects the two-way pipeline by threeway, and one the tunnel is connected with plate-type condenser (4) behind magnetic valve (14), and another road is connected with intercooler (3) with hiigh pressure stage compressor (2) air intake duct respectively behind magnetic valve (13); Hiigh pressure stage compressor (2) blast pipe is connected with plate-type condenser (4); Plate-type condenser (4) refrigerant outlet pipeline is divided into two-way behind reservoir (8) and device for drying and filtering (9), the magnetic valve (11) of leading up to is connected with intercooler (3) with heating power expansion valve (6) back, and another road directly is connected with heating power expansion valve (7) by magnetic valve (10); Intercooler (3) refrigerant liquid outlet conduit is connected with heating power expansion valve (7) behind magnetic valve (12); Heating power expansion valve (7) outlet links to each other with outdoor finned-tube evaporator (5); Plate-type condenser (4) is connected with water pump (15) with water tank (16) by water pipe.
By structure described above, this installs under outdoor low temperature environment, adopts the two stages of compression heat pump cycle mode of heating to produce hot water, and open magnetic valve (11), (12), (13) at this moment, and magnetic valve (10), (14) are closed.It utilizes the high-low pressure two-stage compressor to share the required higher compression ratio of operation under the low temperature environment, thereby improved the compression operating mode, improved the gas transmission coefficient, and be aided with the refrigerant flow that the intercooler flow process increases the high pressure condensation end, make heating capacity and heating efficiency obtain bigger raising with respect to ordinary single-stage compressing hot pump water heater.When outdoor environment temperature is higher because the efficient of two stages of compression Teat pump boiler can be lower than the single stage compress Teat pump boiler, so this moment magnetic valve (11), (12), (13) close, open magnetic valve (10), (14), and system switches to the operation of single stage compress endless form.
Cold-producing medium in the heat pump is by outdoor finned-tube evaporator (5) draw heat from outdoor air, pass through compressor work, rising pressure is laggard goes in the cooled plate formula condenser condensation and emits heat, water heats up in the plate-type condenser heat absorption, we can obtain the hot water that higher temperature is fit to bathing thus, Teat pump boiler has absorbed heat from environment, its efficient is higher than electric heater at double.
The beneficial effects of the utility model are: 1. this device is under outdoor low temperature environment, adopt the two stages of compression heat pump cycle mode of heating to produce hot water, utilize the high-low pressure two-stage compressor to share the required higher compression ratio of operation under the low temperature environment, thereby improved the compression operating mode, improved the gas transmission coefficient, and be aided with the refrigerant flow that the intercooler flow process increases the high pressure condensation end, make heating capacity and heating efficiency obtain bigger raising with respect to ordinary single-stage compressing hot pump water heater; 2. when outdoor environment temperature was higher, by the switching of magnetic valve, device can adopt single stage compress heat pump cycle mode to produce hot water, to obtain higher efficient.
