Description

A kind of heat exchange coil device of air-source water heater

Technical field

The utility model relates to a kind of device of air-source water heater, relates in particular to a kind of heat exchange coil device of air-source water heater.

Background technology

The heating for water at present generally has following mode, liquid, solid fuel, electricity and solar energy or the like, and the fuel heating exists problems such as contaminated environment and fuel store, and electricity then has the cost height or receives the big particular problem of weather effect with solar energy heating.

Because the birth of water heater, the mode of heating of above-mentioned water extends in the field of water heater, electric heater, gas heater and solar water heater or the like have occurred.Wherein, electric heater is a cost with the electric power that consumes a large amount of costlinesses, is unfavorable for the reasonable utilization of the energy; In use then there is serious potential safety hazard in gas heater, and report is arranged during the annual poisoning that causes because of the use of gas heater; Conventional solar water heater can not be produced hot water overcast and rainy; The deficiency that can only rely on electrical heating to replenish solar energy; Thereby the wasting phenomenon that also has the energy particularly uses this water heater very uneconomical at some overcast and rainy many southern areas.So; A kind of novel water heater based on the heat pump cycle principle begins on water heater market, to show up prominently; It is to utilize evaporimeter from surrounding environment, to absorb heat energy (solar energy, air or water etc.), and through condenser heat energy is discharged into and goes in the water, thereby realizes the production of hot water.That Teat pump boiler has is energy-efficient, environmental protection, advantage such as safe and reliable, can round-the-clockly use.Energy crisis is just more and more seriously restricting the fast development of Chinese national economy; The seriousness of just can let us recognizing this problem from " severe power shortage " of outburst in all parts of the country in nearly this year fully aware ofly; Therefore; The development energy-conserving product is that country supports, the act of common people's benefit, has wide development and application prospect.

But the product structure of the air-source water heater that generally occurs on the market is complicated; Fault rate is high; Inefficiency adopts at present the efficient of Teat pump boiler heat conversion when operation work of contrary Carnot cycle relatively poor, and great amount of heat is not transmitted all and to be wasted in the water tank and can not to be used.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provide a kind of simple in structure, easy for installation, capacity usage ratio is high and the heat exchange coil device of heat exchange obvious results air-source water heater.

The utility model solves the technical scheme that its technical problem adopted:

A kind of heat exchange coil device of air-source water heater; Comprise heat exchange coil; Heat exchange coil is connected with the first throttle device; The other end of first throttle device is connected with orifice union, and wherein aforementioned orifice union comprises first check valve, second check valve and second throttling arrangement, the parallelly connected first throttle device that leads to the inlet of second check valve of the inlet of first check valve.

As further design: the parallelly connected outdoor heat exchanger that leads to of second check valve outlet with second throttling arrangement to the aforementioned techniques scheme; The parallelly connected indoor heat exchanger that leads to second throttling arrangement of first check valve outlet, orifice union is between first throttle device and outdoor heat exchanger.

Or: the parallelly connected indoor heat exchanger that leads to of second check valve outlet with second throttling arrangement, the parallelly connected outdoor heat exchanger that leads to of first check valve outlet with second throttling arrangement, orifice union is between first throttle device and indoor heat exchanger.

As the further design to the aforementioned techniques scheme: the aforesaid first throttle device and second throttling arrangement are capillary or heating power expansion valve.

The beneficial effect of the utility model is: the utility model improves the heat exchange efficiency of air-source water heater through orifice union etc., has simple in structurely, easy for installation, and Energy Efficiency Ratio is high, energy savings, use economical, low cost and other advantages.

Description of drawings

Fig. 2 is the second syndeton sketch map of the utility model.

The specific embodiment

With reference to Fig. 1 ~ Fig. 4; The heat exchange coil device of a kind of air-source water heater of the utility model; Comprise heat exchange coil; Heat exchange coil 6 is connected with first throttle device 7, and the other end of first throttle device 7 is connected with orifice union 8, and said orifice union 8 comprises first check valve 81, second check valve 82 and second throttling arrangement 83; The parallelly connected first throttle device 7 that leads to of the inlet of first check valve 81 with the inlet of second check valve 82; 82 outlets of second check valve export and second throttling arrangement, the 83 parallelly connected indoor heat exchangers 2 that lead to second throttling arrangement, 83 parallelly connected outdoor heat exchanger 3, the first check valves 81 that lead to, and orifice union 8 is between first throttle device 7 and outdoor heat exchanger 3; Certainly; Orifice union 8 also can be between first throttle device 7 and indoor heat exchanger 2; At this moment; 82 outlets of second check valve export and second throttling arrangement, the 83 parallelly connected outdoor heat exchangers 3 that lead to second throttling arrangement, 83 parallelly connected indoor heat exchanger 2, the first check valves 81 that lead to, and orifice union 8 is between first throttle device 7 and indoor heat exchanger 2.

Preferably; The first throttle device 7 and second throttling arrangement 83 are selected capillary, heating power expansion valve for use or by two capillaries and the composite set that check valve is formed; Throttling such as capillary, heating power expansion valve device is with respect to electric expansion valve; Because the restriction of capillary or heating power expansion valve adjustable range, all just need shield with check valve.

The above, the just preferred embodiment of the utility model, the utility model is not limited to above-mentioned embodiment, as long as it reaches the technique effect of the utility model with same or analogous means, all should belong to the protection domain of the utility model.
