Technical field:
The present invention relates to water heater, relate in particular to heat pump type water heater.
Background technology:
Hot water product in the market is divided into two big classes: immediately heating water heater and displacement type water heater.Positive displacement electric heater, solar vacuum-tube water heater and conventional household heat pump water heater all belong to the positive displacement hot water product; Gas heater, instant electric water heater belong to immediately heating water heater.The hot water product compares with positive displacement, and Instant heating type hot water product has the advantage convenient and swift, that volume is small and exquisite, and therefore gas heater also occupies certain water heater market share; But the instant electric water heater does not form main product, main because its having relatively high expectations to electric load, the instant electric water heater needs about 10 kilowatts power could satisfy normal bathing needs under the low situation of water temperature in winter, and this load can't bear with electric line normally in China family at present.So the electric heater product that occupies certain share on the market is mainly based on positive displacement.
The Teat pump boiler product is made hot water with the work of electric energy drive system by absorbing air-energy.The energy input output ratio of heat pump product can reach more than 1: 3, and energy-saving effect is obvious.But the Teat pump boiler service behaviour is subjected to the influence of air themperature, and heat capacity changed along with season, can't guarantee to be thermal effect, so heat-pump hot-water product in the market is based on positive displacement.By the unit continuous operation, low power heat-pump apparatus just can provide the hot water of big cubical content, has technical and economic performance preferably.The hot water product is the same with other positive displacements, for more hot water is provided, just need bigger water tank to come water storage, and the water tank that needs pressure-bearing type often, for some families and commercial user, floor space is than the water tank of big and pressure-bearing, and the congested of higher price of bringing and housing space usually allows them be difficult to accept, and therefore influenced the popularization and the use of Teat pump boiler.
Goal of the invention:
The technical problem to be solved in the present invention provides a kind of heat pump type water heater, does not need the heat storage box (being above-mentioned water tank) of larger volume and pressure-bearing, promptly can be heat energy efficiently is provided when the user uses hot water, uses the effect of hot water near instant heating.
The present invention is achieved through the following technical solutions:
A kind of fast-heat type hot pump heater, comprise compressor, heat exchanger, throttling arrangement, evaporimeter and be communicated in by said sequence between refrigerant line; Described heat exchanger comprises heat storage box, is arranged at the heat-exchange device in the heat storage box, and the heat accumulation carrier of filling in heat storage box; Described refrigerant line is communicated with heat-exchange device; Described heat-exchange device constitutes by refrigerant line is in parallel with tap water pipe line, or is bushing type by both and constitutes.
Described heat-exchange device constitutes by refrigerant line is in parallel with tap water pipe line, be meant refrigerant line with tap water pipe line radially tube wall fit in closely; Both can or be squeezed into parallel-connection structure by welding between the tube wall, form direct heat conduction contact-making surface, and contact-making surface is big more, heat transfer efficiency is high more; The cross section of heat-exchange device as described is for " order " font or for " day " font or for the sphere of movements for the elephants type or for " 8 " font or be the candied haws on a stick serial type or have point of contact or the porous form of face for other, wherein a part of hole is the passage of cold-producing medium, and another part hole is the passage of running water.
Described heat-exchange device is sleeve type structure, is to be placed in the tap water pipe line outer wall by refrigerant line to constitute, and the medium that flows in the pipe in the sleeve pipe is a water, and the medium that flows between pipe and the outer tube in the sleeve pipe is a cold-producing medium.
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 present invention 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 present invention 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 present invention can save 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: among the present invention 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.
