Constant-temperature dehumidification heat pump air conditioning unit for indoor swimming pool

Abstract

The invention discloses a constant-temperature dehumidification heat pump air conditioning unit for an indoor swimming pool, and belongs to the technical field of air conditioning units. The heat pumpair conditioning unit comprises a steam compression type refrigeration circulation device, wherein the steam compression type refrigeration circulation device comprises indoor unit systems and outdoor unit systems; the indoor unit systems comprise compressors, an evaporator, an indoor condenser, a water-cooled condenser, liquid storage devices and filters, wherein the compressors are connected with the water-cooled condenser and the outdoor unit systems; the water-cooled condenser is sequentially connected with the liquid storage devices and the filters through one-way valves, and the filtersare connected with the evaporator through expansion valves; the evaporator is connected with the compressors through the expansion valves; and the compressors are connected with the indoor condenserthrough first four-way valves. According to heat pump air conditioning unit, in the use process, moisture in indoor air of the swimming pool is removed, meanwhile, the indoor air is sufficiently keptin a constant-temperature state, so that the functions of condensation heat recovery and exhaust heat recovery are achieved at the same time.

Description

technical field [0001] The invention belongs to the technical field of air conditioning components, and further relates to an indoor swimming pool constant temperature dehumidification heat pump air conditioning unit. Background technique [0002] Due to the evaporation of the water surface in the indoor swimming pool, it is easy to fill the room with humid and chlorine-containing air, especially when the relative humidity is high (greater than 65%), which has a great impact on human health, and even seriously endangers human health. When the air encounters a colder object, condensed water will condense. On the one hand, the condensed water will cause fog, affecting indoor swimmers to watch the outdoor environment; on the other hand, because the condensed water in the indoor swimming pool contains a lot of chlorine, it will corrode the building decoration. , In serious cases, it will cause dangers such as house decoration collapse.

Problems solved by technology

[0005] 1. With traditional ventilation and dehumidification, the indoor volume of the swimming pool is generally required to have an exhaust air volume of 3 times per hour. This will cause a large loss of heat in the swimming pool room in winter, and a large loss of cooling capacity in the swimming pool room in summer.

In order to supplement the energy lost by the swimming pool, in the traditional ventilation and dehumidification method, the swimming pool has to use boilers, central air conditioners, etc. to provide a large number of heat sources or cold sources to replenish energy in the swimming pool, which consumes a lot of energy costs

[0006] 2. The air-conditioning box controls the temperature through the cooling and heating cycle, but since there is no cold water source in spring, autumn and winter, it cannot control the indoor air humidity of the swimming pool, but can only control the air temperature

[0008] Problems of this method: (1), large investment; (2), not conducive to centralized control; (3), energy offset will occur, not energy-saving; (4), heat recovery function cannot be realized, and there is no fresh air ventilation function ; (5), poor airflow organization, mutual interference of dehumidification, air-conditioning air supply and return air systems; (6), no space saving; (7), no anti-corrosion measures; (8), comparison of equipment selection during the design process Complex; (9), heavy equipment maintenance workload; (10), relatively high requirements for operators

[0010] Problems with this method: (1), there will be energy offset, and no energy saving; (2), heat recovery function cannot be realized; (3), no anti-corrosion measures; (4), the selection of equipment during the design process is more complicated ; (5), heavy workload for equipment maintenance; (6), high investment cost; (7), poor indoor aesthetics; (8), high requirements for operators
