Constant-temperature and constant-humidity ice-source heat pump unit

Abstract

The invention provides a constant-temperature and constant-humidity ice-source heat pump unit, which comprises a refrigerant outer unit and a constant-temperature and constant-humidity coil fan; the refrigerant outer unit comprises an outer unit housing, a filling chamber, a fan, an ice-source solution accumulating tank, a water-fluorine exchanger and a circulating water pump; a refrigerant port of the water-fluorine exchanger is connected with a refrigerant pipe inlet of the constant-temperature and constant-humidity coil fan through a valve bank; a refrigerant return port of the water-fluorine exchanger communicates with a reversing four-way valve; amongst the other three ports of the reversing four-way valve, one port communicates with an outlet of a compressor, while the other port communicates with an inlet of the compressor through a vapor-liquid separator and the rest one port communicates with a refrigerant return pipe of the constant-temperature and constant-humidity coil fan. The constant-temperature and constant-humidity coil fan has the advantages of compact structure and low cost; further, a refrigerating medium that may not be frozen at 30 DEG C below zero exchanges heat with air as a refrigerant or a heating agent, and the generated refrigerant is used for the constant-temperature and constant-humidity unit to refrigerate or heat; as a result, the energy consumption is remarkably reduced; moreover, the constant-temperature and constant-humidity ice-source heat pump unit is adaptive to cold weather environments.

Description

technical field [0001] The present invention belongs to the field of ice source technology, specifically a constant temperature and humidity unit. Background technique [0002] The existing constant temperature and humidity units all adopt the air-cooled structure of the outdoor unit, the refrigeration system uses a compressor, the heating system uses a finned electric heater, and the constant humidity system uses a humidifier imported from the indoor unit. This type of unit has the following problems: the electric heating system and the refrigeration system consume a lot of power, especially the electric heating system is more than twice that of the refrigeration system, and the side effect of dehumidification will also occur during cooling , the cost of the whole unit is high, the environmental requirements for the unit are also high, and the cooling and heating energy consumption is relatively large.
