Abstract
The utility model discloses an air conditioning device with quick-switchable heat recovery mode, which comprises a condensation and evaporation system, a refrigeration heat exchanger and a cooling heat exchanger, wherein the condensation and evaporation system comprises a compressor and a gas-liquid separator in ring connection through a pipeline in the middle. A four-way reversing valve is connected in series with a refrigerant medium pipeline under liquid state and one drain pipe of the four-way reversing valve is connected with a domestic hot water exchanger; and then the domestic hot water exchanger is connected to the liquid inlet of the four-way reversing valve. The four-way reversing valve is additionally arranged on a condensation tube, so that degradation in air-conditioning performance and damage on heat recovery device because heat recovery mode is not adopted in part of the heat recovery system of an air-conditioning system are avoided, and the heat recovery mode and non-heat recovery mode can be quickly switched over.
Description
Technical field
The utility model relates to aircondition, is specifically related to a kind of aircondition that can switch heat recovery mode fast.
Technical background
At present, the portion of hot recovery system of known air-conditioning system is by compressor, the air-conditioning system that condenser, evaporimeter, heat reclamation device are cascaded and form.When the user uses heat recovery mode, by flow through heat reclamation device and produce heat exchange with the heat reclamation device water system and reclaim heat for user's use of refrigerant in the air-conditioning system.But, when the user does not need to use heat recovery mode, refrigerant still needs the heat reclamation device of flowing through in the air-conditioning system, because at this moment the heat reclamation device water system is in and stops the water circulation state, long-term place of heat reclamation device and this dry-fire condition cause the refrigerant can't heat exchange in heat reclamation device, if can make the fouling of heat reclamation device internal water system system, influence air-conditioning system recuperation of heat amount, cause the air-conditioning system performance to descend and the heat reclamation device damage.
The utility model content
The novel technical problem that will solve of this experiment is to provide a kind of and can is using heat recovery mode and not use the aircondition that switches fast in the heat recovery mode.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of aircondition that can switch heat recovery mode fast, comprise the condensation evaporation system, freezing heat-exchanger and cooling heat exchanger, freezing heat-exchanger and cooling heat exchanger all are provided with the water inlet and the delivery port of distribute heat, the condensation evaporation system comprises compressor and gas-liquid separator, middle by the connection of pipeline annular, be filled with the refrigerant medium of gas-liquid state in the circulating line, refrigerant medium pipeline under the liquid condition is connected with cooling heat exchanger with freezing heat-exchanger, in each pipeline temperature sensor is installed, refrigerant medium pipeline place under liquid condition is serially connected with four-way change-over valve, a drain pipe of four-way change-over valve connects domestic hot-water's interchanger, domestic hot-water's interchanger connects the four-way change-over valve inlet again, and another root drain pipe of four-way change-over valve directly connects the four-way change-over valve inlet; Four-way change-over valve one liquid outlet connects cooling heat exchanger, and a liquid outlet connects the refrigerant medium pipeline, and an other liquid outlet connects freezing heat-exchanger, and domestic hot-water's interchanger is provided with water inlet and delivery port, and is provided with attemperating unit.
The utility model is added in condenser pipe after the above-mentioned four-way change-over valve, can control the condensed fluid domestic hot-water's interchanger of flowing through, and carry out heat exchange with extraneous water source, reach the recovery thermal source, provide life to act on easily, this control switched system both can avoid the portion of hot recovery system of air-conditioning system to cause the air-conditioning system performance to descend when not using heat recovery mode and heat reclamation device damages, and can use heat recovery mode and not use the purpose of quick running mode switching in the heat recovery mode.
