Description

A kind of segmentation bypass defrost heat pump

Technical field

The utility model relates to a kind of segmentation bypass defrost heat pump.

Background technology

Heat pump is a kind of by the device of the heat energy transfer of low-temperature heat source to high temperature heat source, is also the new energy technology that the whole world receives much attention.Heat pump normally first obtains low grade heat energy from natural air, water or soil, through electric power acting, and then provides the high-grade that can be utilized heat energy to people.In prior art, the common Defrost method of heat pump is by reverse for the indoor and outdoor heat exchanger of unit switchover operation defrosting, then heat exchanger switches back work again, recover Heating State, such Defrost method principle is fairly simple, but energy consumption is large, job insecurity, affects the service life of compressor, there is potential safety hazard.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of segmentation bypass defrost heat pump, reasonable in design, and structure is simple, working stability, and energy-conserving and environment-protective are economic and practical.

For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of segmentation bypass defrost heat pump, comprise the compressor, condenser, evaporation coil, the evaporimeter that connect successively, described evaporation coil is provided with independently three sections of coil pipes: C1 coil pipe, C2 coil pipe and C3 coil pipe, and described C1 coil pipe is connected with compressor and condenser respectively by S1 first magnetic valve, V1 first throttle valve; Described C2 coil pipe is connected with compressor and condenser respectively by S2 second magnetic valve, V2 second throttle; Described C3 coil pipe is connected with compressor and condenser respectively by S3 the 3rd magnetic valve, V3 second throttle.

Beneficial effect:

The utility model adopts technique scheme to provide a kind of segmentation bypass defrost of a kind of segmentation bypass defrost heat pump heat pump, and reasonable in design, structure is simple, working stability, and energy-conserving and environment-protective are economic and practical.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, a kind of segmentation bypass defrost heat pump, comprise the compressor 1, condenser 2, evaporation coil 3, the evaporimeter 4 that connect successively, described evaporation coil 3 is provided with independently three sections of coil pipes: C1 coil pipe 31, C2 coil pipe 32 and C3 coil pipe 33, and described C1 coil pipe 31 is connected with compressor 1 and condenser 2 respectively by S1 first magnetic valve 5, V1 first throttle valve 8; Described C2 coil pipe 32 is connected with compressor 1 and condenser 2 respectively by S2 second magnetic valve 6, V2 second throttle 9; Described C3 coil pipe 33 is connected with compressor 1 and condenser 2 respectively by S3 the 3rd magnetic valve 7, V3 second throttle 10.

During real work,

1, a kind of segmentation bypass mode of this flow scheme design: in a dish situation, evaporation coil is designed to independently 33 3 sections, C1 coil pipe 31, C2 coil pipe 32 and C3 coil pipe, can some sections be designed to by system;

2, in the whole defrost process of system, temporally progress opens S1 respectively, S2, S3 magnetic valve;

3, this kind of segmentation bypass defrost mode can effectively be different from conventional bypass mode, main feature is: under the constant prerequisite of system tolerable bypass hot gas amount, the hot gas amount that circulates in the other pipe of unit are of segmentation Defrost mode increases, and defrosting temperature increases, and defrosting speed and effect increase.

4, this kind of segmentation bypass design can be used for air source heat pump system, air-cooled heat pump unit, trigeneration heat pump system.As schemed signal.

Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
