Description
Technical field
The utility model is related to a kind of novel air source heat pump defrost equipment, belongs to air conditioner technical field.
Background technology
Net for air-source heat pump units as air-conditioning system Cooling and Heat Source, because its is easy for installation, the features such as run simple to operate,
In recent years considerable progress has been obtained.But to winter due to environment temperature, the phenomenon of frosting occurs in surface cooler so that table is cold
Device heat exchange efficiency declines, and has a strong impact on the heating capacity of unit, reduces the Energy Efficiency Ratio of unit.
Current air-source in the market, most common defrost form has two kinds：
First, translative mode defrost, is exactly that unit has arrived defined condition, operational mode conversion in heating operation after frosting
Into refrigeration mode.This pattern is also most common one kind in current air-source market, because fairly simple easy to operate.But lack
Point is relatively more：
1. wasting the energy, because winter refrigeration is idle work, the electricity used during unit operation is wasted；
2. defrost pattern is carried out when unit is heated, that is, refrigeration mode, it can reduce original hot water temperature, influence
Heating effect；
3. when unit is converted to defrost pattern by heating mode, during which compressor needs stopping to restart, so frequent
Start-stop, the service life of compressor can be reduced.
2nd, hot gas defrosting, this method is a kind of emerging defrost pattern of air source heat pump recent years.It is in compressor
Exhaust bypass one arrives surface cooler air inlet, by controlling back pressure, to control to bypass break-make, hot gas is entered surface cooler,
Reach the purpose of defrost.The advantage of this method is exactly without changing the operational mode of unit with regard to that can reach the effect of defrost, phase
Than the mode with transformation mode defrost, the appearance of idle work is not resulted in, will not be damaged the life-span of compressor yet, but thisization
White pattern has the shortcomings that a kind of fatal.Precisely due to it is the break-make that bypass is controlled by pressure, so it cannot be complete
Full defrost, it is impossible to by white complete thawing, may result in the case that surface cooler is having frost always and exchanged heat, cause heat exchange
The waste of area, and due to surface cooler can not defrost completely, may result in refrigerant heat exchanger incomplete so that compressor has
The possibility of liquid hammer.So this heat exchange pattern never has popularization and come.
Utility model content
The purpose of this utility model is exactly in order in view of the above-mentioned problems, a kind of new defrost instrument of offer and pattern, are compared
In two kinds of above-mentioned defrost patterns, the utility model overcome fallen it is above-mentioned in flog a dead horse and the incomplete shortcoming of defrost, simultaneously
The advantage of evaporating temperature can be improved.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of novel air source heat pump defrost equipment,
Including surface cooler, condenser, wherein, the surface cooler includes U-shaped copper at least provided with water heating pipe at 1, further water heating pipe
Pipe；Electrical heating wire is provided with the U-shaped copper pipe, U-shaped copper pipe one end is provided with water inlet and delivery port；The condenser is through the first water
Pipe connects the water inlet of water heating pipe, wherein be connected with elevator pump on the first water pipe, and the delivery port of further water heating pipe is through the
Two water pipes connect condenser.
Preferably, the water heating pipe is distributed between surface cooler comb.
Preferably, the condenser is plate type heat exchanger, double pipe heat exchanger or finned heat exchanger.
Preferably, the elevator pump is horizontal single-stage single suction Piping Centrifugal Pumps.
Preferably, when the water heating pipe quantity is more than at 1, the water inlet of each water heating pipe is parallel to the first water jointly
Pipe.
Preferably, when the water heating pipe quantity is more than at 1, the delivery port of each water heating pipe is parallel to the second water jointly
Pipe.
The beneficial effects of the utility model are：Condenser forms a cyclic system by water pipe in the presence of elevator pump
System, whole equipment has the advantages that defrost without translative mode, without stopping compressor, not flogging a dead horse, improve evaporating temperature.

Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail.Elaborate many details in order to abundant in the following description
Understand the utility model.But the utility model can be implemented with being much different from other manner described here, this area
Technical staff can do similar improvement in the case of without prejudice to the utility model intension, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
It should be noted that when an element is considered as " connection " another element, it can be directly to separately
One element may be simultaneously present centering elements.Unless otherwise defined, all technologies used herein and section are academic
Language is identical with belonging to the implication that those skilled in the art of the present utility model are generally understood that.Herein of the present utility model
Term used in the description is intended merely to describe the purpose of specific embodiment, it is not intended that new in limiting this practicality
Type.Term as used herein "and/or" includes the arbitrary and all combination of one or more related Listed Items.
As shown in Figure 1 and Figure 2, a kind of novel air source heat pump defrost equipment, including surface cooler 1, condenser 2.Wherein, table
