Abstract
The utility model relates to a defrosting device and heat control equipment. The defrosting device is used in the heat control equipment, arranged in the heat control equipment, and comprises an infrared emitter arranged on one side of an evaporator of the heat control equipment and an infrared receiver arranged on the other side of the evaporator, wherein the infrared emitter and the infrared receiver are oppositely arranged and connected through an infrared signal; and a relay is arranged on the infrared receiver and used for controlling a four-way valve in the heat control equipment. The heat control equipment can perform defrosting only when the evaporator has frost, so that the electric energy is saved, the energy efficiency of the hat control equipment is improved, and the service life of the heat control equipment is prolonged.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of defroster and the heat control equipment with this defroster.
Background technology
There is the defective of the not thorough and frequent defrost of defrost when at present, the heat control equipment such as air-conditioning and heat pump moves in the winter time.Take heat pump as example, when winter operation heats, the defrost mode of heat pump has following two kinds: a kind of is the time defrost, under this kind mode, after heat pump moved a setting-up time in the winter time, no matter the evaporator surface of this heat pump has or not frosting, cross valve just was automatically converted to the defrost pattern and carries out defrost, approximately 60 seconds time, automatically restore to after defrost finishes and heat mode of operation; Another kind is the temperature defrost, under this kind mode, arrange at evaporator surface a TEMP mouth is installed, temperature is adjustable from 0--10 ° of C defrost,-10 ° of C to be set as example, the evaporation oral thermometer surface temperature that detects evaporimeter when temperature sensor reaches 0.1 ° of C of-10 ° of positive and negative temperature difference of C() time, central processor CPU sends command signal and begins defrost, about 60 seconds defrost time, the complete automatic recovery of defrost heats mode of operation.
Under above-mentioned defrost mode; air-cooled unit or the equipment such as air source heat pump, air-conditioning operation when heating in winter often can appear; some evaporator surfaces have overworked a thick layer of frost; main frame also heats in operation, especially snow day or air humidity large in evaporator surface very easily hang frost, northeastward during subzero 30 ° of dry and cold weather of C; obviously frostless on evaporimeter; in defrost, waste electric energy in the time of can finding the main frame operation, greatly reduced efficiency.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of defroster and heat control equipment, improves the efficiency of heat control equipment.
For solving the problems of the technologies described above, the utility model proposes a kind of defroster, be used for heat control equipment, described defroster is arranged in heat control equipment, the RF transmitter and the infrared receiver that is arranged on described evaporimeter opposite side that comprise evaporimeter one side that is arranged in heat control equipment, described RF transmitter is oppositely arranged with infrared receiver and is connected by infrared signal, be provided with relay on described infrared receiver, described relay is used for controlling the cross valve of heat control equipment.
Further, above-mentioned defroster also can have following characteristics, and described RF transmitter and infrared receiver are fixed on support.
Further, above-mentioned defroster also can have following characteristics, and described heat control equipment is air source heat pump, air-conditioning, Teat pump boiler or air-cooled unit.
For solving the problems of the technologies described above, the utility model proposes a kind of heat control equipment, comprise the described defroster of above-mentioned any one.
Heat control equipment of the present utility model just carries out defrost when on evaporimeter, frost being arranged, do not carry out defrost when frostless on evaporimeter, thereby saved electric energy, has improved the efficiency of heat control equipment, and has extended the service life of heat control equipment.
Description of drawings
Fig. 1 is the position relationship schematic diagram between heat control equipment middle infrared (Mid-IR) transmitter, infrared receiver and evaporimeter in the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
In the utility model embodiment, heat control equipment comprises evaporimeter, cross valve, be arranged on the RF transmitter of evaporimeter one side and be arranged on the infrared receiver of evaporimeter opposite side, be provided with relay on infrared receiver, this relay is used for controlling cross valve.RF transmitter is oppositely arranged with infrared receiver and is connected by infrared signal.RF transmitter and infrared receiver have consisted of the defroster in the heat control equipment.Fig. 1 is the position relationship schematic diagram between heat control equipment middle infrared (Mid-IR) transmitter, infrared receiver and evaporimeter in the utility model embodiment.
Wherein, RF transmitter and infrared receiver can be fixed on support.
Infrared light beam only has the wing intermediate gap of Pervaporation device, just can complete the work that transmits and receives of infrared signal between RF transmitter and infrared receiver.The wing intermediate gap of evaporimeter is in 2 millimeter.The wing intermediate gap of evaporimeter is inside and outside penetrating when the heat control equipments such as heat pump or air-conditioning work, this moment, the infrared signal of RF transmitter emission can be received by infrared receiver, when the evaporator surface frosting, because the extension frost of evaporator fin is more and more thicker, finally cause the wing intermediate gap that infrared light beam can not the Pervaporation device, infrared receiver does not receive the infrared signal of RF transmitter emission.The conducting when infrared receiver receives infrared signal of relay on infrared receiver does not disconnect when receiving infrared signal.
The defrost operation principle of the utility model heat control equipment is: when on evaporimeter, frost being arranged, infrared receiver does not receive the infrared signal that RF transmitter sends, the very thick defrost condition that reaches of frosting of evaporator surface is described, the relay contact of infrared receiver disconnects, cross valve switches to heating mode, the cold-producing medium antikinesis makes the evaporimeter defrost; After defrost was complete, frostless on evaporimeter, infrared receiver can receive the infrared signal that RF transmitter sends, the contact conducting of the relay of infrared receiver, and cross valve switches to refrigeration mode, and cold-producing medium forward moves, and evaporimeter begins refrigeration.Wherein, forward operation refers to the operational mode of cold-producing medium when refrigeration, and antikinesis refers to the operational mode of cold-producing medium when heating.
Wherein, heat control equipment can be air source heat pump, air-conditioning, Teat pump boiler, air-cooled unit etc.
Heat control equipment of the present utility model just carries out defrost when on evaporimeter, frost being arranged, do not carry out defrost when frostless on evaporimeter, thereby saved electric energy, has improved the efficiency of heat control equipment, and has extended the service life of heat control equipment.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
