Abstract
The invention discloses a vapor compression heat pump water heater device with two compressors, which comprises at least two compressors, a radiator, a water tank, a throttling element, an indirect heat exchanger and an evaporator, wherein the compressor is connected with a heat pump cycle in parallel, the outlet end of each compressor is connected with the radiator, and the inlet end of each compressor is connected with the evaporator; the radiator is arranged in the water tank and connected with the throttling element through a pipeline, and the throttling element is communicated with the evaporator through the pipeline. When the rapid hot water is not required, the heat pump cycle is operated by one of the compressors, namely the energy-saving purpose of higher energy efficiency ratio is realized; when the indoor air source is used in winter, the obvious change of distribution of the indoor air temperature field is not caused; when being used in summer, the indoor local temperature drop can be caused, which plays a role in cooling a room; the invention can control noises without bringing the overlarge noises when being used in the room.
Description
Technical field
The present invention relates to a kind of vapor compression heat pump hot-water heating system, particularly a kind of vapor compression heat pump system that uses two or multi-compressor, cold-producing medium evaporates and absorbs the heat in air source in evaporimeter, this system can be used in the household heat pump water heater device with outdoor or indoor air source as thermal source.
Background technology
In existing family expenses steam compression type air source hot pump water heater heat pump cycle (referring to Fig. 1), after cold-producing medium is compressed by compressor, be discharged in the radiator by compressor, to high temperature heat source (water) release heat and condensation, by throttling, refrigerant pressure and temperature all reduce when passing through restricting element (as capillary, expansion valve) again, enter evaporimeter then, absorb heat and evaporation from low-temperature heat source (air), reenter compressor at last and be compressed, finish a complete cycle.
In the prior art, the commercialization of steam compression type air source hot pump water heater.Its heat pump cycle adopts the single compressor structure, uses the outdoor air source.This type of Teat pump boiler, the evaporator with heat pump assembly is arranged in outdoor, and the water tank of heat pump radiator or built-in radiator can be arranged in outdoor or indoor.The Teat pump boiler of this structure, during its operation of heat pump, particularly compressor is that its heat pump heating capacity relatively is difficult to man's activity, control when deciding the compressor of rotating speed, noise also is difficult to control during its operation of heat pump.And, the air source hot pump water heater of this structure, the part of heat pump installment work is to carry out outdoor, particularly when high-rise building is installed, its installer has certain security risk, and off-premises station is installed insecure risk of falling in addition, and the water heater off-premises station also influences the attractive in appearance of place building and even whole macroscopic view zone.
Present existing air source hot pump water heater, its heat pump cycle are the single compressor circulation, do not have the related content of heat pump heat output control and noise control aspect, and the shortcoming research of these two aspects has also retrained operation of heat pump and can only utilize the outdoor air source.
Summary of the invention
The purpose of this invention is to provide a kind of domestic air source heat pump hot water apparatus that can carry out heat pump heating capacity output control, compressor noise control, its heat pump cycle adopts two or more compressors, can with open one of them or simultaneously a plurality of compressors come the operating heat pump circulation, come artificially to control heat pump heating capacity and noise by this way.When limiting, can adopt the operation of heat pump mode of only enabling one of them compressor to the hot water supply of Teat pump boiler is not free.At this moment, the heat pump of the more compressor operating of heating capacity of the heat pump of a compressor operating is little, but heat exchange area was bigger when the relative multi-compressor of its evaporator area moved, and operation of heat pump will obtain higher relatively Energy Efficiency Ratio, and general operation of heat pump is saved electric power more; Compare with the single compressor heat pump, under the power that adds up of the multi-compressor situation identical with single compressor power, when the unlatching multiple pressure contracts one of them compressor operating of heat pump, its compressor horsepower will be about the part of single compressor heat pump, at this moment, baby compressor operation noise will obviously be in less level; Also have, during the baby compressor operation of heat pump, its caloric receptivity to the air source also reduces relatively, if use indoor air source, the variation of indoor air temperature field are very little to the influence of the mankind and indoor environment with not obvious, at this moment, its evaporator assembly is indoor, indoorly installs and fixes simply relatively, avoided outdoor mounted and destroyed troubles such as building is attractive in appearance; When the heat pump high heating capacity is exported if desired, open a plurality of compressors simultaneously, maximum heating load can be provided, satisfy the domestic hot water and supply needs.
In order to realize above-mentioned task, the technical solution that the present invention takes is as follows:
A kind of vapor compression heat pump hot water apparatus that adopts double-compressor, comprise compressor, radiator, water tank, restricting element, indirect heat exchanger, evaporimeter, it is characterized in that, described compressor is for being at least two, compressor parallel is connected in the heat pump cycle, the port of export of each compressor connects radiator, and the arrival end of each compressor connects evaporimeter; Radiator is built in the water tank, and connects restricting element by pipeline, and restricting element is communicated with evaporimeter by pipeline.
The present invention realizes heating capacity output control and noise control by controlling one of them compressor operating or plural compressor moves simultaneously, and purpose of energy saving.
The present invention compared with prior art has the following advantages and the high-lighting effect: when not needing rapid hot water, use one of them compressor to come the operating heat pump circulation, promptly realized the more energy-conservation purpose of high energy efficiency ratio; When using indoor air source, can when using winter, can not cause tangible change again to the indoor air temperature field distribution, when using summer, can cause indoor local temperature to descend, the refrigerant effect in room is arranged; Can control noise again, indoor use not brought excessive noise, only, very convenient simultaneously in indoor installation, avoided outdoor mounted to use all drawbacks of bringing.
