The utility model content
The purpose of this utility model provides a kind of directly-heated type air source heat pump, to overcome conventional water heaters and solar water heater above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of directly-heated type air source heat pump comprises hot-water heating system and heat pump, and described hot-water heating system comprises magnetic valve, check valve, pressure gate valve and the hot water heat exchanger that connects successively by water pipe; Described heat pump comprises hot water heat exchanger, electric expansion valve and the evaporimeter that connects successively by pipeline, and described evaporimeter is connected with cross valve, and described cross valve also is connected with gas-liquid separator, compressor and hot water heat exchanger respectively; Flow media in the described hot-water heating system is water, and the circulatory mediator in the described heat pump is refrigerant.
Further, described pressure gate valve is by the pipeline between high pressure refrigerant capillary connection hot water heat exchanger and the cross valve.
The beneficial effects of the utility model are: a kind of directly-heated type air source heat pump that the utility model provides, the thermal efficiency is higher than combustion gas and fuel-oil water heater far away, be higher than electric heater and solar water heater, and operating cost is lower than above-mentioned water heater, and there is not the discharging of waste water, waste gas and used heat, Environmental Safety efficient height.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the system construction drawing of the described directly-heated type air source heat pump of the utility model embodiment.
Among the figure:

The specific embodiment
As shown in Figure 1, the described a kind of directly-heated type air source heat pump of the utility model embodiment comprises hot-water heating system and heat pump, and described hot-water heating system comprises magnetic valve 2, check valve 3, pressure gate valve 4 and the hot water heat exchanger 5 that connects successively by water pipe 1; Described heat pump comprises hot water heat exchanger 5, electric expansion valve 7 and the evaporimeter 8 that connects successively by pipeline 6, and described evaporimeter 8 is connected with cross valve 9, and described cross valve 9 also is connected with gas-liquid separator 11, compressor 12 and hot water heat exchanger 5 respectively; Flow media in the described hot-water heating system is water, and the circulatory mediator in the described heat pump is refrigerant.The pipeline 6 that described pressure gate valve 4 connects between hot water heat exchanger 5 and the cross valve 9 by high pressure refrigerant capillary 10.
On the operation principle of basic principle based on refrigeration system of the described directly-heated type air source heat pump of the utility model embodiment.Refrigeration system (compression-type refrigeration) generally is made up of four parts: compressor, condenser, choke valve, evaporimeter.Its course of work is: the liquid refrigerant of low-temp low-pressure (refrigerant), at first absorb heat and be gasificated into low-pressure steam from low-temperature heat source (for example chilled water) in evaporimeter.Refrigerant gas is compressed into the steam of HTHP in compressor then, and this high temperature and high pressure gas is condensed into highly pressurised liquid by low-temperature heat source (for example cooling water) cooling in condenser.Become the low-temp low-pressure liquid refrigerant through restricting element (capillary, heating power expansion valve, electric expansion valve etc.) throttling again.So just finish a kind of refrigeration cycle.
The basic principle of the directly-heated type air source heat pump that provides specific to the utility model: it mainly is made up of compressor 12, gas-liquid separator 11, hot water heat exchanger 5, electric expansion valve 7 and evaporimeter 8 etc.After connecting power supply, the aerofoil fan entry into service of evaporimeter 8, outdoor air carries out heat exchange by evaporimeter 8, air after temperature reduces is discharged system by fan, simultaneously, the refrigerant medium heat absorption vaporization of evaporimeter 8 inside is inhaled into compressor 12, compressor 12 is compressed into high temperature with this low pressure refrigerant Working medium gas, gases at high pressure are sent into hot water heat exchanger 5, the water that is forced in the hot-water heating system circulate is also by hot water heat exchanger 5, send to for the user after being heated by refrigerant medium and use, and refrigerant medium is cooled into liquid, inflow evaporator 8, the periodic duty so repeatedly again after electric expansion valve 7 throttlings cooling of this liquid, heat energy in air is delivered in the water by continuous " pump ", the water temperature of 5 li of hot water heat exchangers is raise gradually, reach at last about 55 ℃, just in time be fit to people's bathing.
