Technical field
The utility model is related to a pair of powered air source heat source machines to be vented defrosting system, be mainly used for ammonium hydroxide air source heat pump
The defrost of heating system.
Background technology
Air source heat pump is a kind of to make the energy saver that heat flows to from low level heat energy air high-order heat source using high potential.
In air source heat pump heating system, air heat exchanger is responsible for the work that heat is absorbed from surrounding air, but in cold north
In use, if environment temperature is less than 0 DEG C, vapor will be precipitated from air and freeze the table for being attached to heat exchanger for side
Face had not only hindered heat transfer, but also has blocked the channel of air circulation, causes the decline of heat exchange efficiency and heat exchange amount, when serious, will cause
Heat exchange can not be carried out effectively.The prior art is to solve the problems, such as that air heat exchanger low temperature is easy frosting, usually increases four-way valve
Reversed defrosting device or electrical heating defrosting device, but the reversed defrosting device of four-way valve is at work, the compressor of air source heat pump
It must stop heat supply and reversely make refrigeration operation, therefore system heating load is significantly affected；Although and electrical heating defrosting device reality
Border defrost effect is ideal, but is needed using electric heating tube using electrical heating defrost, this makes the energy consumption of air source heat pump increase
Greatly, and then its energy-efficient advantage is made not existed, in addition, the service life of electric heating tube is limited, and caused in the presence of overheat on fire
Possibility, also have hidden danger in terms of safety.
Utility model content
The purpose of this utility model is：A kind of air source heat pump system defrosting device simple in structure, easy to use is provided.
The technical solution of the utility model is：A kind of air source heat pump system defrosting device, including be used to be attached to outdoor
The Defrost heater on air heat exchanger surface, the Defrost heater include heat exchange branch pipe and the fixation of several spaced and parallel settings
It is connected to the air inlet manifold and outlet air manifold at each heat exchange branch pipe both ends, interval is laid with heat exchange fin between each heat exchange branch pipe,
The both ends of the outlet air manifold are connected to ambient atmosphere, are equipped on the air inlet manifold for connecting ammonia generator exhaust emissions
The waste heat connecting tube of mouth.
The caliber of the heat exchange branch pipe is 12-16mm.
The quantity of the heat exchange branch pipe is 16-18.
Spacing between adjacent two heat exchange fin is 1.5-2.5mm.
The caliber of the outlet air manifold is more than the caliber of air inlet manifold.
The air source heat pump system defrosting device of the utility model is mounted on the air heat exchanger surface of heat pump system, remaining
It is thermally connected pipe and introduces the exhaust heat that ammonia generator generates, the temperature of defrosting device is made to be consistently higher than the frosting of air heat exchanger
Temperature, to make the air heat exchanger of heat pump system be in frost-free state always, heat pump unit works in the case of frostless,
The evaporation capacity and heat exchange amount for improving unit reduce the energy consumption that heat pump unit itself needs defrost, to greatly enhance
The air source heat pump system defrosting device of the heat absorption capacity of unit, the utility model is simple in structure, easy to install and use, not only may be used
To reduce device fabrication input cost, simplify device systems, operation is more smooth, while can also be by the ammonia in heat pump unit
The delivery temperature of gas generator bottoms out, and discharge is condensed water and a small amount of tail gas, improves the same of the utilization rate of energy
When also reduce discharge, reduce atmosphere pollution.
Description of the drawings
Fig. 1 is the structural schematic diagram that the double dynamical air-source heat source machine of the utility model is vented defrosting system.
Specific implementation mode
The concrete structure of the double dynamical air-source heat source machine exhaust defrosting system of the utility model is as shown in Figure 1 comprising
Defrost heater for being attached to outdoor air heat exchanger surface, the Defrost heater include changing for several spaced and parallel settings
The both ends of hot leg pipe 1 and the air inlet manifold 2 and outlet air manifold 3 for being fixedly connected on 1 both ends of each heat exchange branch pipe, outlet air manifold 3 connect
Logical ambient atmosphere is equipped with the waste heat connecting tube 5 for connecting ammonia generator exhaust port on air inlet manifold 2, is respectively changing
Interval is laid with heat exchange fin 4 between hot leg pipe 1.Wherein, respectively heat exchange branch pipe 1 is that metal pipe material is made, and caliber is 12-
16mm, quantity are 16-18, so that each heat exchange branch pipe 1 is formed smoothly hot-air channel and can heat effectively be passed to air
Heat exchanger；The caliber of outlet air manifold 3 is more than the caliber of air inlet manifold 2, and air draft can be made more smooth；Mounted on each heat exchange branch pipe
Heat exchange fin 4 on 1 is aluminum fin-stock, and a fin pitch of fins is 1.5-2.5mm, the air heat exchanger with the heat pump unit of actual use
On a fin pitch of fins it is suitable, the heat exchange fin 4 on Defrost heater is laid staggeredly with the fin on heat pump unit air heat exchanger,
Heat transfer efficiency can be increased.
Defrost heater in the utility model is mounted on the air heat exchanger surface of heat pump unit, and size can be with
Air heat exchanger is identical, and ventilation quantity is slightly larger than the ventilation quantity of air heat exchanger, and Defrost heater and the air heat exchanger are parallel
It uses, the waste heat discharge of ammonia generator can be guided into sky by connecting the waste heat connecting tube of ammonia generator exhaust port
On gas heat exchanger, to make the temperature of brethaid be in frosting temperature or more always, in practical application, on Defrost heater
Fin temperature be consistently higher than 3 to 5 times of frosting temperature or more, effectively avoid heat pump unit air heat exchanger surface knot
Frost achievees the purpose that unit is run without frosting, while can also effectively improve the utilization rate of energy, reduces discharge, reduces air
Pollution.
