Abstract

The utility model discloses a quickly heating type hot air pump water heater comprising a compressor, a heat interchanger, a throttling gear, an evaporator and refrigerant pipes which are communicated among the previous components; wherein, the heat interchanger comprises a heat accumulating tank, a heat exchange device positioned in the heat accumulating tank and a heat storing carrier which is filled in the heat accumulating tank. The refrigerant pipes are communicated with the heat exchange device; and the heat exchange device is composed of one of the refrigerant pipes and a running water pipeline in a parallel manner or extension type. The utility model makes flowing running water undergo a converse heat exchange with the heat storing carrier in the heat accumulating tank and a hot air heating medium, thereby realizing a quick heat exchange and a high heat exchange efficiency, thus, the utility model may use hot water at the same time of heating once a proper hot air pump set is adopted. The utility model, in case of a constant heat supplying volume, may ensure a smaller volume of the heat accumulating tank and simultaneously is unnecessary to bear pressure because the heat accumulating tank rather than the a water tank which is used for connecting with a running water pipeline for water supply is a container for the heat storing carrier, thereby cutting down the manufacturing cost of hot air pump products greatly.

Described heat-exchange device is the setting of spiraling in the heat storage box of heat exchanger, or is the formation setting.This dual mode can be determined according to designing requirement, no matter is any set-up mode, and when running water flowing water supply and heat pump heated work, cold-producing medium and running water were reverse flow in heat-exchange device.Tap water pipe line in the described heat-exchange device is a copper pipe or for stainless steel tube or for galvanized pipe.With copper pipe is good, its heat transfer efficiency height.

The import and export of described heat-exchange device and heat storage box are connected by refrigerant line, tap water pipe line between importing and exporting, and the refrigerant line, the tap water pipe line that are positioned at heat storage box are isometric, or tap water pipe line is longer than refrigerant line.In order to strengthen running water heat absorption intensification effect, in heat storage box, tap water pipe line advances before the heat-exchange device or after going out heat-exchange device can increase by one section heat exchange pipeline, carries out heat exchange with the heat accumulation carrier.

Beneficial effect:

Compare with conventional household heat pump water heater, the utlity model has following advantage:

One, dwindle the water tank volume: conventional domestic heat pump hot-water heating system adopts coil heat exchanger, and the water in the water tank is mobile poor, and the heat pump in the coil pipe heats having a narrow range of temperature of water in medium and the water tank in addition, so the heat transfer rate is slow; The utility model allows mobile running water heat accumulation carrier and heat pump direct and that heat storage box is interior heat the medium reverse heat-exchange, so the heat transfer rate is fast; So under equal heating load situation, the utility model can be saved heat storage box 1/3 or more (that is water tank, same down) volume, dwindles the occupation of land space of product, helps the marketing of product.

Two, the cancellation press-bearing water tank: in the utility model since heat storage box be the container of heat accumulation carrier, and the water storage box that disconnected water supply pipe is used for supplying water, therefore do not need pressure-bearing, thereby the cisten mechanism of household heat pump water heater can be become not pressure-bearing form by the pressure-bearing form, reduce the manufacturing cost of heat pump product greatly, help the marketing of product equally.

Three, improve the heat pump operating efficiency: a part of heat energy that heat pump work provides is used for heating the heat accumulation carrier in the heat storage box, more heat energy that heat pump work provides are two media directly exchanges in the reverse flow process, at this moment, heat pump moves under the lower state of condensation temperature, efficient is higher, so, heat pump efficiency height in giving the direct heating process of water at low temperature, energy-saving effect is also more outstanding.

Four, overcome the generation of incrustation scale: the heat accumulation carrier in the heat storage box can use less scaling demineralized water, wet goods, running water in the feed pipe is discharged by the hot water that the lower temperature in when inlet directly is heated into about 50 degree, also less scaling, therefore, fast-heat type hot pump heater can guarantee heat pump service behaviour long-term stability.
