Description
Technical field
The utility model is a kind of air-conditioning heat pump ice system, especially a kind of air conditioner and heat pump unit chassis ice system.
Background technology
Air conditioner heat pump system includes evaporator, chassis, compressor and condenser, and in operation of air conditioner, often there is icing on chassis
The phenomenon that, in order to eliminate the heap ice on chassis, following several methods are usually used in the prior art：
Chassis heating tape is fixed on evaporator in the following, with chassis heating tape to chassis ice, due to chassis heating tape by one,
It is easily bent, the cooperation on itself and chassis is made gap occur, so heat transfer coefficient is small, change ice effect is poor, and energy consumption is higher.
The refrigerant of condensator outlet is flowed to base of evaporator by two, using refrigerant waste heat to base of evaporator progress ice,
Realize refrigerant supercooling function simultaneously.Although the technology can solve base of evaporator ice, chassis heap ice problem cannot be solved.
Condensator outlet refrigerant pipe is fixed on the outside of chassis by three, with refrigerant waste heat to chassis heatingization ice.Due to refrigerant
Pipe is contacted with generally line between chassis, so heat exchange area is small, heat-transfer effect is poor, limited to chassis ice ability.
Invention content
The purpose of this utility model is to overcome the defect of existing chassis ice system heat transfer coefficient smallization ice effect difference,
Invent a kind of air conditioner and heat pump unit chassis ice system heated to chassis using heater and improve heat exchange area and energy utilization rate
System.
The purpose of this utility model is realized as follows：The air conditioner and heat pump unit chassis ice system,
Including throttle part, evaporator, chassis, heater, condenser, compressor and four-way valve, heater is built-in with heat exchange coil, adds
Heat transfer plate is equipped at the top of hot device；Chassis is fixed below evaporator, and heater is fixed below chassis；Compressor connects with four-way valve
Mouth D connections, four-way valve interface C are connect with condenser, and condenser is connect with the heat exchange coil in heater, heat exchange coil and throttling
Component connects, and throttle part is connect with evaporator, and evaporator is connect with four-way valve interface E, and four-way valve interface S connects with compressor
It connects.
Coordinate for plane between the heater and chassis.
The good effect of the utility model is as follows：
（1）Raisingization ice effect：Plane is made in the heater upper end for heating chassis, improves contact of the heater with chassis
Area, to raising ice effect.
（2）Improve energy utilization rate：Refrigerant system condenser outlet refrigerant exhaust-heat absorption is recycled, to improve the energy
Utilization rate reduces system energy consumption.
（3）Improve refrigeration system heating capacity and Energy Efficiency Ratio：Refrigerant heat release twice in condenser and heater cools down, and improves
Refrigerant degree of supercooling, to improving the heating capacity and Energy Efficiency Ratio of refrigeration system.

7 interface C of valve is connect with condenser 5, and condenser 5 is connect with the heat exchange coil 8 in heater 4, heat exchange coil 8 and throttle part 1
Connection, throttle part 1 are connect with evaporator 2, and evaporator 2 is connect with 7 interface E of four-way valve, and 6 interface S of four-way valve connects with compressor 6
It connects.
Coordinate for plane between the heater 4 and chassis 3.
The operational process of the utility model is as follows：
At runtime, high temperature and pressure refrigerant flows to 7 interface D of four-way valve to the utility model by compressor 6, then by four-way valve
7 interface C flow to 5 heat release of condenser cooling, and the refrigerant after heat release cooling flows to the heat exchange coil 8 in heater 4 by condenser 5,
By heat exchange coil 8, heat release cools down refrigerant again, and the refrigerant after heat release cooling flows to throttle part 1, refrigerant warp by heat exchange coil 8
Throttle part 1 flows to evaporator 2 after throttling, refrigerant of the refrigerant after 2 interior suction thermal evaporation of evaporator, heat absorption evaporation is by evaporator 2
7 interface E of four-way valve is flowed to, compressor 6 is then flowed back to by 7 interface S of four-way valve.
Refrigerant exchanges heat by heat exchange coil 8 in heater 4, and heater 4 is made to heat up, and heater 4 is passed by top
The heat of heater is transmitted to chassis 3 by hot plate 9, to improve chassis temperature, prevents condensed water under low temperature environment from freezing on chassis
Or heap ice, it is ensured that unit normal operation.
It above are only the composition form for illustrating the utility model and partial function implemented, for those of ordinary skill in the art
For, without departing from the concept of the premise utility, various modifications and improvements can be made is every to press the utility model
Refrigerant waste heat is absorbed by heater come the methods to chassis ice, within the scope of protection of this application.
