Description
Technical field
The utility model relates to a kind of air-conditioner, relates to the air-conditioner that a kind of heater is installed in the heat exchanger air inlet particularly.
Background technology
The air-conditioner of existing charged heater, the warm ability of its system comprise heating efficiency comprehensive of the warm ability of system of refrigerating circulation system of air-conditioning self and electric heater.Air-conditioner is when the warm startup of system, its with heater also start simultaneously, after the refrigerating circulation system system of air-conditioning self warms up the temperature that reaches required, the control device of air-conditioner starts fan warm braw is blown out, then, further heating through electric heater blows out from indoor set, thereby reaches the greenhouse effect.
Fig. 1 and Fig. 2 are respectively the schematic diagrames of the indoor machine of air-conditioner of prior art.Wherein, Fig. 1 is the indoor set schematic diagram of pipe machine in the prior art, and Fig. 2 is the indoor set schematic diagram of cabinet-type air conditioner in the prior art.As shown in Figure 1, the pipe machine indoor set comprises import A, fan 1, heat exchanger 2, electric heater 3 and outlet B.Wherein, electric heater 3 is positioned at the outlet side of heat exchanger 2, between heat exchanger 2 and outlet B.When the warm startup of air-conditioner system, the refrigerating circulation system system of air-conditioning self warms up and the electric heater heating is started working simultaneously, heat exchanger 2 heats up, wind enters indoor set from import A, carry out heat exchange with heat exchanger 2 earlier, in order to make cold wind not blow out one side to the user, when heat exchanger did not reach temperature required as yet, fan 1 can not turn round, and wind does not blow out from heat exchanger 2, though this moment, heater was started working, but fan does not turn round, and can not blow out from outlet B so heater adds hot-air, and the air of heater 3 heating can not be utilized by heat exchanger 2, must be after after a while, the temperature of heat exchanger 3 just can reach certain temperature.When heat exchanger 3 reached uniform temperature, fan 1 just started and will blow out from pad interchanger 2 through the hot blast after over-heat-exchanger 2 heat exchanges, and further heats through electric heater 3, thereby blows out warm braw.Heat exchanger 2 needs certain hour just can reach temperature required, and this moment, heater was started working, and had therefore caused the decline of energy utilization rate, and energy loss increases.
As shown in Figure 2, in the prior art, indoor machine of air-conditioner is a cabinet-type air conditioner, comprises that fan 1 is installed in the bottom of cabinet-type air conditioner, is followed successively by fan 1 from top to bottom, heat exchanger 2 and electric heater 3.When cabinet-type air conditioner started, the warm electric heater heating of the refrigerating circulation system system of air-conditioner started simultaneously, and wind carries out heat exchange from air inlet A inflow heat exchanger 2, and when the temperature of heat exchanger 2 did not reach the temperature of expection as yet, fan 1 did not turn round.When the temperature of heat exchanger reaches desired temperature, fan 1 running, thus will going out through the wind after the heat exchange of over-heat-exchanger 2, the further heating through electric heater 3 blows out warm braw.When heat exchanger 2 does not reach predetermined temperature as yet, although electric heater is started working,, warm braw can not be blown out, so energy utilization rate is low because fan is not worked, energy loss is big.
The heater of existing structure is installed in the air outlet of heat exchanger usually, and purpose is the warm braw that blows out from heat exchanger for further heating, thereby reaches the purpose of rapid greenhouse.But, the weak point of existing structure is, owing to adopt the heating means of heater postposition, though the air of producing by boasting can access rapid heating, but the work that adds hot-air originally because of air-conditioner is the greenhouse by its refrigerating circulation system turns round and carries out, and when the warm startup of system, the refrigerating circulation system of air-conditioner needs certain hour the cold-producing medium of self could to be heated, especially for specific heat bigger compressor and heat exchanger, under the not high situation of indoor heat converter temperature, for guaranteeing the comfortableness in room, control system will not allow cold wind is blown out, and this moment, fan can not move.According to this point, when refrigerating circulation system does not reach uniform temperature at heat exchanger temperature, though heater is started working, but because fan is failure to actuate, can not blow out the warm braw of heater heating, so just cause the energy utilization rate of whole system very low, energy loss is bigger.And the condensed water on the heat exchanger may be fallen on the heater, and causes the heater shortening in service life.
Therefore need a kind of air-conditioner, have heater, can overcome above-mentioned defective, improve efficiency (COP), shorten the thermal starting time of air-conditioner greenhouse operation, and effectively avoid condensed water to drop on the heater, thereby prolong the service life of heater.
