Abstract
The invention relates to a method and a device for defrosting and heating of an air conditioner in winter. A refrigerant of an external unit (an evaporator ) end of an air conditioning heat pump circulation system is heated directly by combusting fuel during heating in winter; and high-temperature gas generated by the combustion of the fuel can be cooled below 10 DEG C by utilizing the low-temperature heat absorption effect of the refrigerant. Since water no longer serves as an intermediate medium, related mechanisms are reduced, and the method is more energy-saving compared with the existing condensation technology; since firing and extinguishment of the device are controlled by the air conditioner uniformly, the device can also be only used for defrosting the external unit of the air conditioner at the right time (such as in a heating transition period and/or a region without pipeline fuel supply); the performance of an air conditioning heat pump is fully exerted; the air conditioning heat pump is more energy-saving; in addition, the interior of a room can be supplied with hot air without stop during the defrosting; the starting-up and rapid heating of the air conditioner are fast; and the feeling of a human body is excellent.
Description
Technical field
The present invention relates to air-conditioning, relate in particular to the defrost of air-conditioning winter heating.
Background technology
The evaporimeter capillary can produce frosting when present heat pump air conditioner heated in the winter time, and air-conditioner defrosting can cause indoor temperature to descend; Air-conditioning intensification ability descends with outdoor environment temperature and progressively diminishes, if temperature almost can not satisfy the heat supply requirement in the time of-5 ℃, can only be aided with electrical heating or cooperate the heating of wall hanging stove to use, but electrical heating power is little, and is big to environment power supply pressure; (0-15 degree centigrade) can not free isolated operation when temperature is high for wall hanging stove and air-conditioner control system disunity, air-conditioning heat pump, causes energy waste; Wall hanging stove and air-conditioning will dispose water system respectively, add hot-water heating system with fuel combustion earlier, and water system heat exchange again causes material manually to reach the space waste; Existing condensation technology needs secondary heat exchange, and EGT is minimum at 40 degrees centigrade, also has the part heat to fail to utilize.
Summary of the invention
Problem at the prior art existence, the invention provides a kind of method and apparatus that is used for air-conditioning defrost in winter and heating with the combustion fuel mode, combustion fuel directly heats the refrigerant of outer machine (evaporimeter) end of the air-conditioning heat pump circulatory system when warming oneself in the winter time, utilize the low temperature heat absorption of refrigerant, can drop to the hot-gas temperature that produces after the fuel combustion below 10 degrees centigrade, cause no longer water is used as intermediate medium, reduced associated mechanisms, compare more energy-conservation with existing combustion gas condensation technology, switch fire by this device of the unified control of air-conditioning, in due course machine (as in the heating transitional period and/or do not have the area of pipeline fuel supply) can also only be used for the outdoor machine of air-conditioner defrost, give full play to the air-conditioning heat pump function, more energy-conservation, and indoor can not stopping by hot blast during defrost, speed was fast when the air-conditioning start heated fast, and human body sensory is splendid.
One of purpose of the present invention provides a kind of air-conditioning and heats method with defrost, reaches the effect of the quick defrost of outdoor machine of air-conditioner, can be used for simultaneously heating fast and/or heating for a long time, has also reduced the number of mechanism, has improved energy utilization rate.
The present invention is achieved through the following technical solutions:
A kind of air-conditioning heats defrosting method, by the combination of combustion fuel mode of heating and air conditioner heat pump system, provides heat with the mode of heating of combustion fuel for the refrigerant of evaporating state in the air conditioner heat pump system, and it is little to take up room, and power is big; Refrigerant with evaporating state in the air conditioner heat pump system absorbs heat from the high-temperature gas of combustion fuel, and the temperature difference is big, and heat exchange is thorough, has improved energy utilization rate.
The medium of heat exchanger heat exchange is the high-temperature gas of combustion fuel generation and the refrigerant that is just circulating in air conditioner heat pump system, because no longer adopting water as intermediate medium, has reduced the number of heat exchange mechanisms, saves cost, can accelerate the speed of heating.
Another object of the present invention provides a kind of air-conditioning and heats defrosting device, comprise heat exchanger, burner, smoke exhaust pipe, drainpipe, controller, heat exchanger is made of refrigerant chamber, air flue, refrigerant import, refrigerant exit, and heat exchanger is series in the air conditioner heat pump system, before the outdoor machine of air-conditioner.
Burner switch fire is by the unified control of air-conditioning, air-conditioning can be closed burner when not required, energy savings or fuel can be adjusted the firepower size according to the task needs, suitably reduce firepower when heating for a long time, only need satisfying does not freeze after water in the high-temperature flue gas and the refrigerant heat exchange cooling gets final product, reduce exhaust gas temperature, energy savings is heating or is suitably strengthening during defrost firepower fast, improve the refrigerant temperature of outdoor machine of air-conditioner, heat fast and melt ice on the outdoor machine of air-conditioner.
Adopting the beneficial effect of the technical program is to make the quick defrost of outdoor machine of air-conditioner, also can be used for heating fast and/or heating for a long time, has also reduced the number of mechanism simultaneously, has improved energy utilization rate.

The specific embodiment
The specific embodiment of the present invention is illustrated by reference to the accompanying drawings.
As shown in Figure 1: heat exchanger 1 of the present invention is double braid covering cartridge type enclosed construction, constituted by refrigerant chamber, air flue, refrigerant import, refrigerant exit, space between the inner/outer tube is refrigerant chamber 2, the space of inner core is air flue 3, refrigerant import 4 connects the compressor of air conditioner outlet, and refrigerant exit 5 connects the outdoor machine of air-conditioner import, heat exchanger 1 one termination smoke exhaust pipes 6, drainpipe 7, another termination burner 8, burner 8 connects controller 9 and is controlled by air-conditioner host.
The corresponding relation of described refrigerant chamber and air flue is a kind of preferred version, certainly, other scheme that the present invention can also adopt those skilled in the art to be familiar with, for example, as shown in Figure 3: adopt finned tube or with the outdoor machine of air-conditioner capillary as the refrigerant chamber, the refrigerant chamber places air flue.
As shown in Figure 1: use warming by air conditioner when winter, air-conditioner host is judged when needing (for example outdoor machine of air-conditioner frosting and/or the area of pipeline fuel supply is arranged), start burner 8 by controller 9, produce high-temperature gas, with the refrigerant direct heat transfer in the refrigerant chamber 2, gas temperature descends and discharges heat exchanger 1 by smoke exhaust pipe 6, the condensed water that gas temperature decline produces is discharged by drainpipe 7, the low temperature refrigerant is entered by refrigerant import 4, be heated the back and enter outdoor machine of air-conditioner from refrigerant exit 5, fall if having frost to be heated on the outdoor machine of air-conditioner to become water droplet, high temperature refrigerant continues in the inlet chamber, be used for air-conditioning internal machine to the room heat supply, when air-conditioner host judge when no longer needing (for example outdoor machine of air-conditioner defrost and/or do not have the area of pipeline fuel supply), close burner 8 by controller 9, air-conditioning recovers conventional state, only by heat pump to indoor heating.
