Abstract
The present invention relates to defrost condenser of heat exchanger and its defrost control method. The condenser has copper pipes and heat radiating fins with wound heating carbon fiber belt and is connected to control instrument with external power source; and the control instrument is connected electrically to the temperature sensor of condenser, water tank, or indoor unit of air conditioner, as well as the compressor. The defrost control method under the control of the control instrument includes the following steps: 1. heating with the heating belt when the temperature t1 of the condenser is lower than 8 deg.c until reaching 15 deg.c; 2. stopping the compressor for 3 min before restarting when t1 is lower than 8 deg.c and heating for over 40 min; 3. maintaining heating when t1 is 8-15 deg.c; and 4. stopping the compressor and the heating belt when the temperature in the water tank reaches 55 deg.c until it lowers to 52 deg.c. The defrost condenser is suitable for heating air conditioner and has high heat efficiency and low power consumption.
Description
Technical field
The invention belongs to the accessory device in the liquid heater that thermal source is arranged, and is specifically related to the defrosting improvement technology of condenser in the heat exchanger outdoor machine.
Background technology
Heat exchanger comprises Teat pump boiler and heating air conditioner, all is provided with off-premises station, and wherein condenser and compressor are its critical piece.Condenser mainly is made up of radiating fin and copper pipe, dress heat transfer medium in the copper pipe, the compressor work that links to each other with copper pipe is compressed into high pressure high temperature vapor with medium, make with the water heater that links to each other in water storage box in the air heat of evaporimeter or cooling/heating air conditioner air conditioner indoor machine heat up.It is the heating equipment that family and hotel, restaurant extensively adopt.But when outdoor temperature was low to winter, particularly frosting easily on the radiating fin of condenser reduced the thermal efficiency, increases energy consumption.Generally to be four-way change-over valve defrost with the heat of medium existing Defrost technology, have in the other dress of condenser heating rod energising heating, these two kinds of Defrost technologies, energy consumption is still bigger, at the bottom of the efficient. just can not defrost below spending subzero 5, can't normally heat.
Summary of the invention
The invention purpose is the shortcoming that will overcome prior art, and the defroster that design and installation can be controlled automatically on condenser can fully guarantee to heat the needs of heating, can cut down the consumption of energy energy savings again.Can both defrost at subzero 15 degree, normally heat.
Take technical scheme for achieving the above object: a kind of heat exchanger comprises the condenser of water heater and heating air conditioner off-premises station, its design feature is to twine heating tape in the exposed part of condenser copper tube and radiating fin upper part, this heating tape is electrically connected with controller, the controller external power supply; On controller and the condenser, all temperature sensors of installing of in the water heater water storage box or cooling/heating air conditioner air conditioner indoor machine hot-air mouth place are electrically connected; Controller also is electrically connected with compressor; The copper pipe of the interior dress heat transfer medium on the condenser connects the heating element of compressor and interior hot vaporizer of water heater water storage box or cooling/heating air conditioner air conditioner indoor machine.
The Defrost method of the condenser of this heat exchanger is controlled automatically by the temperature parameter requirement, can follow these steps to carry out:
1, temperature t on condenser
1In the time of≤8 ℃, controller just starts the heating tape on (energising) condenser, and to condenser heat temperature raising defrosting, when condenser temperature 〉=15 ℃, controller cuts off the power supply to heating tape, stops heating;
2, as condenser temperature t
1In the time of≤8 ℃, and the heating tape continuous operation is after 40 minutes, and controller sends instructions and made compressor shutdown 3 minutes, then continues to start compressor and heats, and this moment, heating tape was cheated whole heating work;
3, when condenser temperature＞8 ℃ and＜15 ℃, heating tape is worked always;
4, as water heater water storage box water temperature (t
2) reach 55 ℃ or cooling/heating air conditioner indoor air temperature (t
2) when reaching 18 ℃, controller all quits work compressor and heating tape, when this temperature dropped to 52 ℃ (15 ℃), then the two started work again.
The outstanding advantage and the remarkable result of the invention:
1, this condenser defroster is simple in structure, can start automatically as required or turn-offs heating tape or compressor operating, and easy to use, energy-saving effect is obvious;
2, the heat of heating tape by the compressed machine acting of the heat transfer of medium in the copper pipe, plays the secondary heat utilization, significantly improves the thermal efficiency, energy savings.
Description of drawings
Accompanying drawing is the structure annexation schematic diagram of the invention.
The specific embodiment
Specify the embodiment of the invention with reference to accompanying drawing:
Twining high-temperature silica gel carbon fiber heating band 5 on the exposed copper pipe in condenser two ends in a kind of water heater off-premises station 1 and the radiating fin 3 is connected with controller 11 through electric wire 10; The temperature sensor of adorning on the condenser 8 is connected with controller 11, experiences condenser temperature t
1Reach controller; In the copper pipe of dress medium connect compressor 2 and be connected with hot vaporizer 7 in the water storage box 4; Temperature sensor is experienced the temperature t of hot water in the water storage box
2Be connected with controller through electric wire 6; Controller 11 links to each other with supply socket 12, and electric wire 9 connects compressor 2 and controller 11.Controller adopts the complete intelligent Automatic Detection and Control of single-chip microcomputer.
If be used for heating air conditioner structure annexation and above-mentioned water heater roughly the same; The water storage box that just indoor set of cooling/heating air conditioner is replaced water heater.
