Compared with the prior art, the multi-temperature direct-thermal heat pump water heater adopts the plurality of heat exchangers to progressively heat the cold water, therefore, the low- temperature, middle- temperature, and high- temperature hot water can be supplied, and different requirements of water-temperature can be met, the utility model is consistent with the life use or the industrial use, the practicability and the economical efficiency of the product are improved.
Description
Technical field:
The utility model relates to the hot water machine technical field, refers in particular to a kind of heat pump water-heating machine.
Background technology:
Heat pump water-heating machine is a kind of refrigerant compression cycle of utilizing driven compressor, with the transfer of heat of low-temperature heat source in heated water, thereby produce the equipment of domestic hot-water or industrial hot water.Heat pump water-heating machine generally is made up of compressor, evaporimeter, gas-liquid separator, expansion valve, heat exchanger and other component.Common directly-heated type heat pump water-heating machine generally just adopts single heat exchanger to export a kind of hot water of temperature, and water temperature is lower, can not satisfy life or industrial demand, also causes thermal waste simultaneously.
Summary of the invention:
The purpose of this utility model is to provide a kind of directly-heated type heat pump water-heating machine that the hot water of various temperature can be provided simultaneously.
The utility model purpose again provides a kind of structure optimization, and cost is low, makes full use of the directly-heated type heat pump water-heating machine of heat energy.
For achieving the above object, the utility model adopts following technical scheme:
A plurality of heat exchangers are set in heat pump water-heating machine, and cold water each heat exchanger of flowing through successively forms heat temperature raising step by step, and offers the hot water supply opening at the output end of hot water of whole or local heat exchanger.
The hot water supply opening is provided with the pressure gate valve, and the pressure gate valve of the hot water supply opening of sophisticated heat exchanger is connected on the thermal source output pressure of low one-level.
Be compared with the prior art, the utility model adopts a plurality of heat exchangers to cold water heat temperature raising step by step, and the hot water of various temperature such as low temperature, middle temperature, high temperature can externally be provided thus, satisfies different water temperature requirements, meet life or industry utilization, promote the practicality and the economy of product.
The utility model advantage again is simple in structure, and cost of manufacture is low, through multistage heat exchange, can utilize heat energy better, reduces the condensation heat waste, energy savings.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:
See also shown in Figure 1, it is the structural representation of the preferred embodiment of the utility model, the utility model is relevant directly-heated type heat pump water-heating machine, comprise compressor 1, evaporimeter 2, gas-liquid separator 3, expansion valve 4 and a plurality of heat exchanger 5, cold water each heat exchanger of flowing through successively, form heat temperature raising step by step, and offer hot water supply opening 6 at the output end of hot water of whole or local heat exchanger.
In the present embodiment, in unit, establish three heat exchanger 5a, 5b, 5c, wherein, heat exchanger 5a is the output high-temperature water, heat exchanger 5b is warm water in the output, heat exchanger 5c is the output water at low temperature, the work that is water route part 7 is: cold water inserts heat exchanger 5c earlier, carries out the heat exchange first time, forms the water of lower temperature, export then through pipeline and insert among the heat exchanger 5b, carry out the heat exchange second time, warm water in the formation is exported through pipeline again and is inserted among the heat exchanger 5a, carry out heat exchange for the third time, form high-temperature water.Therebetween, offer hot water supply opening 6 respectively at heat exchanger 5a, 5b output end of hot water, warm water and high-temperature water in promptly externally providing, supply opening 6 water temperatures height can be transferred by corresponding control section and establish, in present embodiment, be provided with pressure gate valve 8 at the hot water supply opening, utilize the relation of temperature and pressure to transfer and establish, thereby obtain the water of ideal temperature, can make 40 ℃～50 ℃ hot water as middle temperature, high temperature can be made 80 ℃～90 ℃ hot water, and concrete water temperature is adjusted by actual needs.In the present embodiment, the pressure gate valve of the hot water supply opening of sophisticated heat exchanger is connected on the thermal source output pressure of low one-level, realizes promptly that also two stage pressures carry out monitor water temperature, promotes service behaviour and temperature adjustment accuracy.
Consult shown in Figure 1, the work of the utility model thermal source part (refrigerant) is: compressor 1 gets the gas that electric work is compressed into refrigerant high temperature, high pressure, output then, high-pressure switch 11 is opened, the gas of high temperature, high pressure is sent among heat exchanger 5a, 5b, the 5c successively, and it flows to opposite with the cold water flow direction just, and the gas of high temperature, high pressure carries out heat exchange with water in heat exchanger, the gas that is high temperature, high pressure is emitted heat, and water is realized heating up after should absorbing heat.The gas of high temperature, high pressure is from last heat exchanger 5c output and through becoming the gas-liquid two-phase body of low temperature, low pressure behind corresponding device for drying and filtering and the expansion valve 4, and then enter in the evaporimeter 2 vaporization and absorb heat energy in air, the low pressure refrigerant after the heat absorption is sucked by compressor 1 and enters next circulation.
In the present embodiment, between evaporimeter 2 and compressor 1, also be provided with gas-liquid separator 3 and low pressure switch 9, to promote the service behaviour of unit.Also be provided with one at high temperature, the high-voltage output end of compressor 1 and be close to logical 12 inputs of receiving evaporimeter 2, be close to logical 12 and be provided with magnetic valve 13, to realize defrost function.
More than diagram is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so every principle according to the utility model is done the equivalence variation or modified, and all should be covered by in the protection domain of the present utility model.
