Governing system for constant temperature and constant humidity and integral constant temperature and humidity machine

Abstract

The invention discloses a governing system for constant temperature and constant humidity, comprising a compressor, a first heat exchanger, a throttling device, a second heat exchanger, a third heat exchanger, an indoor air flue, an outdoor air flue, a wetting device, a four-way reversing valve, a first proportional valve and a second proportional valve, wherein the compressor, the first heat exchanger, the throttling device and the second heat exchanger are connected in series to form a circulation loop; the third heat exchanger is connected with the second heat exchanger in parallel; the indoor air flue is provided with an indoor fan, the first heat exchanger and the heat exchanger; the outdoor air flue is provided with an outdoor fan and the third heat exchanger; the wetting path of the wetting device is communicated with the indoor air flue; the first port of the four-way reversing valve is connected with the air suction port of the compressor, the second port is connected with the first heat exchanger, the third port is connected with the exhaust port of the compressor, and the four port is connected with the node of the second heat exchanger and the third heat exchanger; and the first proportional valve and the second proportional valve are respectively installed on a refrigerant pipeline on which the second heat exchanger and the third heat exchanger are arranged. The invention can enlarge the temperature adjusting range when a complete machine operates and avoid the temperature adjusting dead zone. The invention also provides an integral constant temperature and humidity machine.

Description

technical field [0001] The present invention relates to a compression machine, device or system with reversible cycle, specifically a constant temperature and humidity adjustment system and an integrated constant temperature and humidity machine. Background technique [0002] At present, most of the household integrated dehumidifiers sold on the market are ordinary heating types, and the indoor air supply temperature is higher than the operating environment temperature. In many dehumidification environments, especially in high temperature and high humidity conditions, excessively high air supply temperature It often brings discomfort to users; at the same time, ordinary integral dehumidifiers only have a dehumidification function, and blindly dehumidifying cannot effectively adjust the humidity of the environment and place. In order to meet the requirements of specific environment and place for specific temperature and humidity, and better meet the needs of human comfort, it...

Problems solved by technology

This control method, because the heat exchange air volume or water flow of the outdoor condenser has no obvious effect on the distribution of the condensation heat of the indoor condenser and the outdoor condenser, so the unit system cannot reach a certain temperature within the set temperature range under the temperature adjustment state. An interval temperature, this interval temperature is called the "temperature adjustment blind zone" of the system

If the set required temperature is just in the "temperature adjustment blind zone" of the system, it will inevitably cause frequent switching of unit operation, and the room temperature will also fluctuate greatly.
