Example Embodiment

[0047] Example 1

[0048] In this embodiment, a fusion compressor drive-type scaling heat pipe is divided into a wet drying heat pump system, see figure 1 It mainly includes a compressor 1, a condenser 2, a condensation heating heating section 3, a throttle valve 4, an evaporator 5, an auxiliary throttle valve 6, an evaporation pre-cooling section 7, and a fan 8.

[0049] This embodiment employs a jet illin compressor 1 with an intermediate filling port, or two-stage compressed forms in series with two compressors.

[0050] The refrigerant flowing out of the condensed heating section 3 is two, wherein all the way is thrown into the lower saturation temperature of the throttle to enter the evaporator 5, and then enter the compression after absorbing from the air flowing through the air. Machine 1; additionally, the auxiliary throttle 6 is thrown to a higher saturation temperature, and then enter the evaporation pre-cooling section 7. After evaporation from the air flowing through t...

Example Embodiment

[0055] Example 2

[0056] In this embodiment, a fusion compressor drive-type scaling heat pipe is divided into a wet drying heat pump system, see image 3 The main difference from Example 1 is the arrangement of the refrigerant flow path.

[0057] The present embodiment is directly separated from the high-temperature high-pressure refrigerant exit of the compressor 1, wherein the condenser 2 is condensed into the air flowing through the air, and then the flow valve 4 is thrown to the low saturation temperature and enter the evaporator. 5. After the adhesion is evaporated from the end of the air flowing into the compressor 1; the other path enters the condensation and heat-free section 3, which is condensed to reheat the air flowing through the air, and then flows through the auxiliary throttle 6 to the higher saturation temperature after entering The pre-cooling section 7 is evaporated from evaporation from flowing through the air, and the intermediate filling port of the compresso...

Example Embodiment

[0060] Example 3

[0061] This example structure is shown Figure 5 The basic principle is consistent with Example 1. As compared with Example 1, the air flow path in this embodiment did not set the second air branch 11 for the bypass mixture, and thus the condensed heating segment 3 in Example 1 can be combined with the condenser 2, the refrigerant The condensation and overcooling are completed in condenser 2 (the end of the condenser 2 refrigerant passage is a clearance section). At this time, the pre-cooling section 7 and the refrigerant are separated from the condenser 2, which constitutes a rope heat pipe of the compressor driving type in the present invention, and the heat exchange effect of the air before and after the evaporator 5 is realized. This form is compact, high component integration, and is ideal for application scenarios for limited installation space.

Abstract

The invention relates to a dehumidifying and drying heat pump system fused with a compressor driving type quasi-loop heat pipe, which comprises a refrigerant circulating flow path and an air flow path, and the refrigerant circulating flow path comprises a compressor, a condenser, a condensation reheating section, a throttle valve and a refrigerant flow path of an evaporator which are connected in sequence; the dehumidifying and drying heat pump system integrating the compressor driving type quasi-loop heat pipe further comprises an evaporation pre-cooling section connected into the refrigerant circulating flow path. The air flow path comprises an evaporation pre-cooling section, an evaporator, a condensation reheating section and a first air branch of a condenser which are connected in sequence, the evaporation pre-cooling section is used for pre-cooling air return, and the condensation reheating section is used for reheating air return. Compared with the prior art, through the effect of the compressor driving type quasi-loop heat pipe, heat exchange of air fluid in front of and behind the evaporator is achieved, useless cooling effect sensible heat carried by air at an inlet of the evaporator is reduced, the proportion of latent heat corresponding to dehumidification in the total refrigerating capacity is increased, and therefore the dehumidification amount is increased, and the dehumidification energy efficiency is improved.

Description

technical field [0001] The invention relates to a vapor compression heat pump dehumidification and drying system, in particular to a dehumidification and drying heat pump system integrated with a compressor-driven quasi-loop heat pipe. Background technique [0002] The refrigeration heat pump cycle system can be used to replace the traditional electric heating system, greatly reduce power consumption, and promote energy saving and emission reduction and carbon neutral goals. [0003] Compared with solution dehumidification and solid adsorption dehumidification, when the refrigeration heat pump circulation system is used for dehumidification and drying, it has compact structure, stable operation and convenient maintenance. However, the cooling and dehumidification method adopted by the refrigeration heat pump circulation system needs to cool the air to a temperature lower than the dew point first, and then make the air condense to achieve dehumidification. This part of the s...
