Air-conditioning heat pump device with five working modes

Abstract

An air-conditioning heat pump device with five working modes, including compressor, gas-liquid separator, oil separator, first four-way valve, second four-way valve, air-conditioning heat exchanger, outdoor heat exchanger and hot water heat exchange device, the first electronic expansion valve, the second electronic expansion valve and the solenoid valve; the exhaust end of the compressor is respectively connected in parallel with the intake end a of the first four-way valve and the intake end e of the second four-way valve; The air outlet b of the first four-way valve is sequentially connected in series with the air conditioner heat exchanger and the second electronic expansion valve, the air outlet f of the second four-way valve is sequentially connected in series with the outdoor heat exchanger and the first electronic expansion valve, and the second four-way valve is connected in series with the outdoor heat exchanger and the first electronic expansion valve. The gas outlet h of the through valve is connected in series with the hot water heat exchanger and the solenoid valve in sequence; the first electronic expansion valve and the solenoid valve are connected in parallel and then connected to the second electronic expansion valve; the gas outlet c of the first four-way valve is connected to the second The air outlet g of the four-way valve is connected in parallel and then connected in series with the gas-liquid separator and the suction end of the compressor in sequence; adopting the above-mentioned structure, it is possible to obtain a system with the functions of heating water, cooling air, heating, heating, and heating An air-conditioning heat pump device with five working modes of water and cooling air, hot water heating and heating.

Description

technical field [0001] The invention relates to an air conditioner heat pump device with five working modes. Background technique [0002] In the current prior art, air-conditioning heat pump water heaters generally have the following working modes: 1. Hot water only mode; 2. Air-conditioning only mode; 3. Heating only mode; 4. Air-conditioning and hot water mode. However, it is difficult to realize simultaneous hot water and heating modes. Therefore, further improvement is necessary. Contents of the invention [0003] The purpose of the present invention is to provide an air-conditioning heat pump device with five working modes of hot water, cooling, heating, heating, hot water and cooling, hot water and heating, so as to solve the current problems. There are deficiencies in the technology. [0004] An air-conditioning heat pump device with five working modes designed for this purpose, including a compressor, a gas-liquid separator, an oil separator, a first four-way v...
