Description

A kind of low temperature air injection enthalpy-increasing Teat pump boiler
Technical field
The utility model relates to a kind of low temperature air injection enthalpy-increasing Teat pump boiler.
Background technology
The Teat pump boiler kind is a lot of in the market, mainly contains solar energy boosting type, the three kinds of series in water source and air source.Solar energy assisted heat pump is a kind of heat pump techniques that heat pump is used in combination with heliotechnics; Water resource heat pump is that the water source (more than 20 ℃) that utilizes uniform temperature is media with the cold-producing medium as thermal source, with the heat absorption in the water source after compressor compresses heat, to reach heating and to produce the purpose of hot water, water resource heat pump must have the water source of uniform temperature and flow by heat exchanger and cold water heat-shift; Air source heat pump obtains heat with the water resource heat pump similar approach from air and adds hot water.
Air source heat pump is one of state-of-the-art using energy source product in the world today.Along with the live raising of grade of rapid economy development and people, life has become people's daily necessities with hot water, yet traditional water heater (electric heater, fuel oil, gas water heater) has shortcomings such as energy consumption is big, expense is high, seriously polluted; And the operation of energy saving and environment friendly solar water heater is subjected to the restriction of meteorological condition.The heat supply principle of air source heat pump and traditional solar water heater are completely different, air source heat pump is a low-temperature heat source with air, water, solar energy etc., air source heat pump is that power heats domestic water from the low temperature side draw heat with the electric energy, and hot water is directly sent into the user as the hot water supply or utilize fan coil to carry out small size heating by the circulatory system.Air source heat pump is the best solution of the large, medium and small hot water centralizedly supply system in places such as present school dormitory, hotel, bath center.
The existing market like product does not have magnetic valve, sprays electric expansion valve and main electric expansion valve dispatch control system, generally all be the low temperature refrigerant directly to be sent to compressor carry out secondary heating, the temperature of compressor is changed often, and compressor operating efficient is low, and energy-saving effect is not good enough.
The utility model content
The purpose of this utility model provides a kind of low temperature air injection enthalpy-increasing Teat pump boiler, makes compressor operating efficient higher, and energy-saving effect is better.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of low temperature air injection enthalpy-increasing Teat pump boiler, comprise compressor, condenser and evaporimeter, described compressor one side connects gas-liquid separator by pipeline, the compressor opposite side connects plate type heat exchanger by pipeline, compressor top is connected with cross valve by pipeline, cross valve connects condenser by pipeline respectively, gas-liquid separator and evaporimeter, the upper and lower of condenser one side is respectively equipped with hot water outlet and cold water inlet, evaporimeter one side is provided with air inlet, be provided with left side runner and right side runner in the described plate type heat exchanger, the upper end of left side runner connects condenser by pipeline, the upper end of right side runner connects compressor by pipeline, pipeline between left side runner and the evaporimeter is provided with main electric expansion valve, and the pipeline between the bottom of right side runner and the condenser device is provided with magnetic valve and sprays electric expansion valve.
The beneficial effects of the utility model are: high efficiency, good energy-conserving effect.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of low temperature air injection enthalpy-increasing Teat pump boiler of the utility model embodiment.
Among the figure:
1, compressor; 2, cross valve; 3, evaporimeter; 4, gas-liquid separator; 5, plate type heat exchanger; 6, condenser; 7, spray electric expansion valve; 8, magnetic valve; 9, main electric expansion valve; 10, air inlet; 11, hot water outlet; 12, cold water inlet.
The specific embodiment
As shown in Figure 1, the described a kind of low temperature air injection enthalpy-increasing Teat pump boiler of the utility model embodiment, comprise compressor 1, condenser 6 and evaporimeter 3, described compressor 1 one sides connect gas-liquid separator 4 by pipeline, compressor 1 opposite side connects plate type heat exchanger 5 by pipeline, compressor 1 top is connected with cross valve 2 by pipeline, cross valve 2 connects condenser 6 by pipeline respectively, gas-liquid separator 4 and evaporimeter 3, the upper and lower of condenser 6 one sides is respectively equipped with hot water outlet 11 and cold water inlet 12, evaporimeter 3 one sides are provided with air inlet 10, be provided with left side runner and right side runner in the described plate type heat exchanger 5, the upper end of left side runner connects condenser 6 by pipeline, the upper end of right side runner connects compressor 1 by pipeline, pipeline between left side runner and the evaporimeter 3 is provided with main electric expansion valve 9, and the pipeline between the bottom of right side runner and the condenser 6 is provided with magnetic valve 8 and sprays electric expansion valve 7.
During concrete the use, 1 pair of refrigerant of compressor compresses heats, the back high temperature refrigerant of heating flows to cross valve 2, enter the cold water of condenser 6 with heat transferred cold water inlet 12, make temperature of cold water rises form high-temperature-hot-water and discharge hot water outlet 11, high temperature refrigerant flows out the low temperature refrigerant after condenser 6 carries out heat exchange, at this moment the low temperature refrigerant of the magnetic valve 8 of front end and 7 pairs of outflows of injection electric expansion valve is monitored flow, control low temperature refrigerant flows into compressor 1 and carries out secondary heating, thereby play the effect of environmental protection and energy saving, and a large amount of hot gas of the outside generation of water heater at this moment, the air inlet 10 of evaporimeter 3 just sucks thermal current to cross valve 2, enters gas-liquid separator 4 gas is separated with liquid, carries out secondary heating after gas being sent into compressor 1 then, play the effect of environmental protection and energy saving, continue circulation according to aforesaid way subsequently and supply with.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but on its shape or structure, do any variation; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
