Problems solved by technology

As we all know, the existing heat pump water heaters are mainly divided into air energy heat pump water heaters and water / ground source heat pump water heaters. Widely used by users of small projects; while the former mainly heats water by absorbing air heat source, its installation is simple and low in cost, but it is not conducive to the use of waste heat and it is easy to frost in winter, which greatly affects its energy saving and use effect. The scope of application is therefore greatly limited
Although the existing technology can alleviate the above-mentioned shortcomings of the heat pump water heater by increasing the power of the heat pump system, configuring an auxiliary electric heater, and increasing the volume of the water tank, etc., the initial investment of the user will be greatly increased accordingly, or water safety and The energy saving effect is not ideal, and the space occupied by the equipment must also be increased. Obviously, these solutions are not satisfactory

Embodiment 1

[0029] Embodiment 1: An evaporator of a heat pump water heater is mainly composed of a hood (1), an evaporative heat exchanger (2), and a fan (16). The hood (1) includes an outer circulation air duct (3), an inner circulation The air duct (5), the outer circulation air duct (3) and the inner circulation air duct (5) are all made of stainless steel plates. The hood (1) generally can also include an oil filter, an oil collecting cup, a fan, a lighting lamp, etc. In addition, for an automatic cleaning hood, it can also include a flushing pump, a washing cup, a sewage cup or a water inlet and sewage outlet, etc., and its style can include Chinese style, European style, side suction type, etc., which are not described in detail here; the inner circulation air duct (5) includes left air duct (6) and right air duct (7), The left air duct (6) is combined with the outer circulation air duct (3) through heat conduction. The evaporative heat exchanger (2) is a finned tube heat exchanger...

Embodiment 2

[0034] Embodiment 2: An evaporator of a heat pump water heater is similar to Embodiment 1, except that the inner circulation air duct (5) does not include the left air duct (6), the right air duct (7) and the damper (17) ; The evaporative heat exchanger (2) can be made of copper tubes, aluminum tubes, stainless steel tubes or titanium alloy tubes, the evaporative heat exchanger (2) is wound on the outer wall of the outer circulation air duct (3), and is connected with the outer circulation air duct (3) Placed in the inner circulation air duct (5), the air inlet of the inner circulation air duct (5) is on the upper part of the whole structure, and its air outlet communicates with the air inlet of the fan (16), and the fan (16) is fixed on the inner circulation air duct ( 5) On the front air duct wall, the air outlet is outwards and placed at the bottom of the whole structure. In order to enhance the heat exchange effect, some heat exchange fins can be arranged in the outer circ...

Embodiment 3

[0036] Embodiment 3: An evaporator of a heat pump water heater. This embodiment is similar to Embodiment 1, except for the following difference: the inner circulation air duct (5) does not include the left air duct (6) and the right air duct (7), and the outer The circulating air duct (3) and the internal circulating air duct (5) have a common air inlet (4), and both have a common section of the air duct. The fan of the hood (1) can be set at the outer circulating air duct (3). In the air outlet channel that belongs to independently, like this, in different working conditions, the blower fan and fan (16) of hood (1) can work separately or cooperatively.

[0037] The evaporative heat exchanger (2) can be made of copper tubes, aluminum tubes, stainless steel tubes or titanium alloy tubes, or finned tube heat exchangers can be used, which are fixed in the outer circulation air duct (3) and the inner circulation After the common air inlet (4) of the air duct (5), in the common air...

Abstract

An evaporator of a heat pump water heater is characterized in that the evaporator (11) consists mainly of a suction fan (1) and an evaporative heat exchanger (2); the suction fan (1) comprises an outer circulating air channel (3); and the evaporative heat exchanger (2) can be fixed on the suction fan (1) and is in heat conductive combination with the outer circulating air channel (3). The heat pump water heater comprises a compressor (8), a water condenser (9), a throttle device (10) and the evaporator (11). The evaporator of the heat pump water heater provided by invention can absorb waste heat, has frosting resistance, stable performance and high comprehensive performance-price ratio, and is suitable for large-scale application.

Description

Technical field [0001] The invention relates to a heat pump water heater device, in particular to an evaporator of a heat pump water heater and a heat pump water heater, belonging to the technical field of heat pump applications. Background technique [0002] Existing heat pump water heaters are generally mainly composed of compressors, water condensers, throttling devices, evaporators and other components. They have many advantages such as safety, energy saving, low-carbon environmental protection, etc., and have been used by people in a modern society where energy is scarce and pollution is serious. Vigorously promote the application, and the new type of heat pump water heater that has gradually emerged recently can produce hot water and provide cooling and / or heating for air conditioning after being properly equipped with a condenser as an air-conditioning heat exchanger. It has powerful functions and more obvious advantages in energy saving. In the future Or will dominat...
